BloodPril is a capsule labeled Blood Pressure Support: one a day with 8 oz of water, up to two, and 60 capsules a bottle. Each holds a 500 mg blend of L-citrulline and two forms of L-arginine. It is not a blood pressure medicine or an ACE inhibitor. Ask your doctor first if you take blood pressure medicine or have had a heart attack.

Three amino acid forms in every capsule, listed by weight as the label prints them
BloodPril is a 60-capsule supplement sold for blood-pressure support, taken one capsule a day with 8 oz of water, up to two. Start with the credit, because this desk does not often get to give it. This is the best label we have read. There is a real Supplement Facts panel with a serving size and a servings-per-container count. The † Daily Value Not Established footnote is correct, because no Daily Value exists for either amino acid in the blend. There is a full other-ingredients list, which tells a vegetarian buyer the capsule shell is hydroxypropyl methylcellulose rather than gelatin. There is a complete caution statement, a storage line, a safety-seal line, a named distributor with a postcode and a telephone number, a country-of-origin claim in its correctly qualified form — Made in the USA with globally sourced ingredients — and the FDA disclaimer properly asterisked to the single front-panel claim. And then the panel declares one line. Proprietary Blend 500 mg †, with three ingredients underneath and no weight against any of them. Two of those three are the same amino acid in different salts, so the formula is really two substances presented as three. The order is an order of predominance, which gives each a ceiling: at most 500 mg, 250 mg and 167 mg. And the research is in grams. Eight trials of L-citrulline at 3 to 9 g a day, pooling to a systolic reduction of 4.10 mmHg. Eleven trials of L-arginine across 387 participants at 4 to 24 g a day, pooling to 5.39 mmHg. The whole blend is 0.5 g, and 1 g at the label's maximum. Two last things. The brand name ends in −pril, the suffix that marks a class of prescription blood-pressure drugs. And the clinical summary for arginine carries two warnings that appear nowhere on this bottle: an additive effect with blood-pressure medicines, and a mortality signal after heart attack.
Four steps. The first is to give this label the credit it has earned, because the rest of this page is harder on the product than the printing deserves. The fourth is the step that decides everything.
A Supplement Facts panel with a serving size and a servings count. A correct † Daily Value Not Established footnote. A full other-ingredients list. A complete caution statement, storage, a safety-seal line, a named distributor with a town, a postcode and a telephone number, and the FDA disclaimer asterisked to the front claim.
That is more than most packs this desk reads supply, and it is the first thing to say about this product.
The dietary half of that good panel is a single row: Proprietary Blend 500 mg, with L-Citrulline dl-Malate, L-Arginine (Alpha-Ketoglutarate dihydrate) and L-Arginine HCL beneath it and no weight against any of them.
Two of the three are the same amino acid in different salts. So a three-ingredient blend is really two active substances.
A blend is not a blank. Ingredients are listed in descending order of predominance, so the first can be at most the whole 500 mg, the second at most half, the third at most a third.
Those are ceilings, not amounts, and every one is generous to the product. All three ingredients are salts, so part of each weight is malate, ketoglutarate or hydrochloride rather than amino acid.
Both amino acids have real pooled human evidence for blood pressure, which is more than most supplement ingredients can say. Citrulline: eight trials at 3 to 9 g a day, systolic −4.10 mmHg. Arginine: eleven trials, 387 participants, 4 to 24 g a day, systolic −5.39 mmHg.
The whole blend is 0.5 g. At the label's maximum of two capsules it is 1 g, against a 3 g floor.
Every figure in those four steps is printed on this label or computed from the order the label prints the blend in. The trial doses are quoted from the two meta-analyses this desk opened.
Scroll. Each bar is one ingredient's ceiling drawn as a fraction of the lowest dose used in that ingredient's own pooled analysis. Every bar is generous: the real amounts are lower than the ceilings.
No bar here is a printed amount, because none is printed. Each is the most that ingredient can be.
A proprietary blend withholds the individual weights and discloses two things: the total and the order. The order is an order of predominance, so each ingredient has a ceiling. Those ceilings are the only figures this panel permits, and they are the figures drawn here.
The eight pooled trials used 3 to 9 g a day. Three grams is 3,000 mg. Even if the blend were nothing but citrulline, that is one sixth of the lowest dose any of those trials used — and it is not, because two arginines share the same 500 mg.
Second in the order, so at most 250 mg against a 4,000 mg floor across eleven trials and 387 participants. That is about one sixteenth. The third line, the same amino acid as a hydrochloride, is capped at 167 mg.
Two capsules is 1 g of blend against a 3 g floor, spread across three lines, two of which are one substance. It also halves the bottle from 60 days to 30 and doubles the cost per day.

One line on this label decides everything else on this page: a 500 mg proprietary blend of three ingredients, with no weight against any of them. The order they are printed in is the only clue to proportions, and it is the clue this site works from.
Tap a name. The bar is the ceiling that ingredient's position permits, drawn against the lowest dose used in its own pooled analysis — so every bar is already generous to the product.
What our sources record8 trials; doses 3 to 9 g a day
First in the blend, so the largest share of the 500 mg — at most all of it. The meta-analysis we opened pooled eight trials and records that “dosage of L-citrulline supplementation varied from 3 to 9 g/day”. It found a systolic reduction of 4.10 mmHg, and a diastolic result that was not statistically significant overall — reaching significance only in the subgroup taking 6 g a day or more.
Three grams is 3,000 mg. The whole blend is 500 mg. Even if the blend were nothing but citrulline, this is one sixth of the lowest dose any of those trials used. It is not. And dl-malate is a salt: part of that weight is malic acid rather than citrulline.
What our sources record11 trials, 387 participants; doses 4 to 24 g a day
Second in the blend, so at most half of the 500 mg. The meta-analysis we opened included “11 randomized, double-blind, placebo-controlled trials involving 387 participants” at doses “ranging from 4 to 24 g/d”, and found oral L-arginine “lowered systolic BP by 5.39 mm Hg” and “diastolic BP by 2.66 mm Hg”.
Four grams is 4,000 mg. The ceiling here is 250 mg — about one sixteenth of the lowest dose in that analysis. And alpha-ketoglutarate dihydrate is a complex: only part of that weight is arginine at all.
What our sources recordthe same 11 trials, 4 to 24 g a day
Third and last in the blend, so at most a third of the 500 mg — and in practice less, because the first two come before it. Against the same 4 g floor that is about one twenty-fourth.
It is worth saying what this line is: the second arginine on the same panel. Arginine appears twice, as two different salts, which makes the ingredient list look longer than the formula is. Hydrochloride is also roughly 17% hydrochloric acid by weight, so the arginine itself is less again.
Positions are the order the panel prints them in, which is an order of predominance. Every amount here reads “at most”, because the panel declares one 500 mg total for all three and no individual weight. So the first can be at most the whole blend, the second at most half, the third at most a third, and every bar is drawn to that ceiling rather than to a printed figure. The real amounts are lower, and lower again once the malate, the ketoglutarate and the hydrochloride are taken out of the weight.
Six bars. Three are the ceilings the order of predominance permits, one is the label's two-capsule maximum, one is the dose at which the diastolic result became significant, and one is the entire blend against the gentler of the two reference doses.
On most products this desk reads, this chart compares each printed amount with the dose its own research used. This panel prints one amount for three ingredients, so there is no individual figure to draw for any of them.
What is drawn instead is what the panel does permit. A blend discloses a total and an order of predominance, so each ingredient has a ceiling: at most 500 mg, 250 mg and 167 mg. Every bar here is a ceiling rather than an amount, and every one is generous to the product.
The shape of it is the finding. Not one ceiling reaches the lowest dose used in the trials behind that ingredient, and the two closest bars are drawn at the maximum the label permits rather than the serving it recommends.
A ceiling that reaches the dose the trials usedA ceiling that falls short of itThe full scale, 6,000 mgone shared linear scale in milligrams — the upright mark on every row is that row’s reference dose
The only weight on this panel. It covers L-citrulline dl-malate, L-arginine alpha-ketoglutarate and L-arginine HCl together, and no individual figure is printed for any of them.
Six times the entire blend. The pooled analysis found a systolic reduction of 4.10 mmHg at doses from 3 to 9 g a day, with the diastolic result significant only at 6 g and above.
Eight times the whole blend, and sixteen times the ceiling for the larger of the two arginine lines. Those trials covered 387 participants at 4 to 24 g a day.
At the label's single-capsule serving this matches the 60-day refund window exactly. The label also permits two a day, which halves it, and gives no reason to choose.
The lowest per-day figure here, and it assumes one capsule a day for a year. At the label's maximum of two it is $1.63 and the same pack is six months.
No Daily Value exists for either amino acid, so the dagger and the footnote are both right. Small, and worth saying: most labels this desk reads get this wrong.

Tap a numbered marker on the label to read what that line says, and what it leaves out.
| As printed on the panel | Printed amount | % Daily Value |
|---|---|---|
| Proprietary Blend | 500 mg | † |
| L-Citrulline dl-Malate | not published | † |
| L-Arginine (Alpha-Ketoglutarate dihydrate) | not published | † |
| L-Arginine HCL | not published | † |
The blend total is printed and the three parts are not. Be exact about what that means, because the sentence is easy to soften in either direction. It does not mean the amounts are hidden entirely: a blend discloses a total and an order, and the order is an order of predominance. So the first line can be at most the whole 500 mg, the second at most 250 mg, the third at most 167 mg. Those are ceilings, not amounts, and every one of them is generous to the product. What it does mean is that nobody outside the company knows the three real figures, and that includes this desk.
Two of the three names are the same amino acid in different salts, so a three-ingredient blend is really two active substances sharing one 500 mg total. And all three are salts: dl-malate is part malic acid, alpha-ketoglutarate dihydrate is part ketoglutarate and water, and HCL is roughly 17% hydrochloric acid by weight, so the free amino acid sits below each ceiling again.
The footnote† Daily Value Not Established — correct, because no Daily Value exists for either amino acid in this blend
This is the small thing most labels this desk reads get wrong, and this one gets right. A dagger rather than a percentage is the correct mark when no Daily Value has been set, and none has been set for either amino acid.
Other ingredientsHydroxypropyl Methylcellulose (capsule), Microcrystalline Cellulose, Magnesium Stearate
Three, all ordinary, and the first is useful: hypromellose means the capsule shell is cellulose rather than gelatin, so a vegetarian buyer does not have to guess. That is also the one seal on this product the panel actually supports; non-GMO, gluten free and dairy free are claims about the same short list with no certifying body named anywhere.
The percentages, recomputedThere are none to recompute, and that is correct here. A printed percentage is the one number on a panel a reader can check without leaving the label. This panel prints a dagger instead, because no Daily Value exists for L-citrulline or L-arginine. Nothing on this page has been recomputed, because the panel gives a reader nothing to recheck.
One further detail is worth having beside the blend line. The pooled human trials behind both amino acids used grams. Eight trials of L-citrulline at 3 to 9 g a day; eleven trials of L-arginine across 387 participants at 4 to 24 g a day. The whole blend is 0.5 g, and 1 g at the two capsules the label permits. So on this product the amounts are bounded rather than missing, and every bound falls well short of the doses the research used.
A printed percentage is the one number on a panel a reader can check without leaving the label. This panel prints a dagger instead, and the dagger is the right mark.
| Nutrient | Declared | % DV printed | Daily Value | Our figure | Verdict |
|---|---|---|---|---|---|
| Proprietary Blend, 500 mg | † Daily Value Not Established | correct | † | No Daily Value has been established for L-citrulline or L-arginine, so a dagger is the right mark and the footnote is the right footnote. This line is correct and most labels this desk reads get it wrong. | correct |
| The three ingredients inside it | no amount printed | nothing to recheck | — | A proprietary blend discloses a total and an order, and withholds the individual weights. That is legal. It also means the three figures a reader most needs cannot be checked — only bounded. | blend |
A percentage on a panel is the one number a reader can check without leaving the label, and almost nobody does. We recompute every one we find. On this product there were none to recompute, and that is the correct result: no Daily Value has been established for L-citrulline or L-arginine, so a dagger and the footnote beneath it are exactly right.
Credit where it is dueThis is a small thing and most of the labels this desk reads get it wrong, either by inventing a percentage or by leaving the column blank with no footnote to explain it. This panel does it properly, and the other-ingredients list, the caution statement and the asterisked disclaimer on the same wrap are done properly too.
And what still cannot be checkedThe second row. A proprietary blend discloses a total and an order and withholds the individual weights, which is legal and which leaves a reader with no self-service check at all on the three figures that matter most. What can be done is bounding them: at most 500 mg, 250 mg and 167 mg from the order of predominance. That is not the same as knowing them, and nobody outside the company does.
This label gives a reader more than most, and then stops at the one place it matters most.
There is a Supplement Facts panel, with a serving size, a servings count, a correct Daily Value footnote and a full other-ingredients list. And the dietary portion of it is a single line: Proprietary Blend, 500 mg, with L-citrulline dl-malate, L-arginine alpha-ketoglutarate and L-arginine HCl listed underneath and no weight against any of them.
So the three numbers a buyer most needs cannot be read. They can only be bounded, using the order they are printed in.
Ingredients in a blend are listed in descending order of predominance. That single rule is what makes this product reviewable at all.
The first ingredient can be at most the whole blend: 500 mg. The second can be at most half, because otherwise it would outweigh the first: 250 mg. The third at most a third: 167 mg.
Every one of those is generous to the product. The real figures are lower, and both salts dilute further: dl-malate is part malic acid, alpha-ketoglutarate dihydrate is part ketoglutarate and water, and HCl is about 17% hydrochloric acid by weight.
Both of these amino acids have been tested in humans for blood pressure, which is genuinely more than most supplement ingredients can claim. The results are real and modest, and the doses are the point.
L-citrulline: eight trials, “dosage… varied from 3 to 9 g/day”, pooled systolic effect −4.10 mmHg; the diastolic result was not significant except at 6 g a day and above.
L-arginine: “11 randomized, double-blind, placebo-controlled trials involving 387 participants” at “4 to 24 g/d”, systolic −5.39 mmHg, diastolic −2.66 mmHg.
The whole blend here is 0.5 g.
The clinical reference we opened states it directly: ACE inhibitors “most commonly end with the suffix ‘-pril.’ Examples include lisinopril, ramipril, and captopril.”
BloodPril is a dietary supplement. It is not an ACE inhibitor, it contains nothing like one, and its own label says it is not intended to diagnose, treat, cure or prevent any disease.
We make no claim about why it is named this way. We print the fact because the people most likely to recognise that ending are the people this product is sold to.
The single most useful sentence on this site, and it is not on the bottle.
The clinical summary we opened says arginine “may have additive hypotensive effects” with antihypertensives, and tells patients: “Arginine supplements can also lower blood pressure so taking both at the same time may not be safe.”
The same page also carries a warning this desk will not bury: “In patients who had an acute myocardial infarction, arginine supplementation may increase risk of mortality.”
The bottle's caution statement tells people with a known medical condition to consult a physician. It does not mention either of these.
A one-bottle render exists in the artwork supplied with this product. No one-bottle price is sold. The smallest pack is two bottles at $79 each.
At one capsule a day that is 120 days of product bought against a 60-day refund window — even though a single bottle would have matched that window exactly.
Scroll or use the arrows. Six cards, and the first one gives the label the credit the other five spend.
1 line, 3 ingredients
Start with credit where it is due, because this label earns some. There is a real Supplement Facts panel with a serving size, a servings-per-container count, an other-ingredients list, a correct † Daily Value Not Established footnote, a full caution statement, storage instructions, and a named distributor with a postcode and a telephone number. That is more than either of the last two products this desk read supplied.
And then the panel declares one line: Proprietary Blend 500 mg, with three ingredients listed underneath and no weight against any of them.
order = predominance
A blend is not a blank. Two things are disclosed and both are useful.
The total. 500 mg, for everything in the blend together.
The order. Ingredients are listed in descending order of predominance, so the first is the largest. That gives every ingredient a ceiling: the first can be at most the whole 500 mg, the second at most half of it, the third at most a third. Those ceilings are what this site puts beside the research, and they are deliberately generous — the real figures are lower.
6× to 24× short
Both amino acids here have been tested for blood pressure in humans, which is more than most supplement ingredients can say. The trials used grams.
L-citrulline: 3 to 9 g a day across eight trials. L-arginine: 4 to 24 g a day across eleven trials and 387 participants.
The entire blend is 0.5 g. Against the lowest citrulline dose that is one sixth, assuming the blend were pure citrulline. Against the lowest arginine dose the ceiling for the larger of the two arginines is one sixteenth. Even taking the label's maximum of two capsules, the whole blend is 1 g against a 3 g floor.
2 of 3 lines
L-Arginine (Alpha-Ketoglutarate dihydrate) and L-Arginine HCL are both arginine, supplied as two different salts. A three-ingredient blend is therefore really two active substances: citrulline and arginine.
That matters for how the formula reads at a glance — a list of three sounds fuller than a list of two — and it matters for the ceilings, because splitting one substance across two lines pushes each line further down the order of predominance.
−pril
This is the finding this desk would want a reader to carry away before any other. −pril is the suffix that marks a class of prescription blood-pressure drugs: the ACE inhibitors. The clinical reference we opened says it plainly — “These medications most commonly end with the suffix ‘-pril.’ Examples include lisinopril, ramipril, and captopril.”
This is a dietary supplement, sold for blood pressure, named BloodPril. We are not alleging that anyone intended a reader to confuse it with a prescription medicine. We are saying that a person managing their blood pressure, who recognises that ending from the box in their cupboard, is being handed a reason to make exactly that mistake.
60 capsules, 60 days
At the label's one-a-day serving, 60 capsules is 60 days, and the refund window is 60 days from purchase. Those line up precisely, which is unusually tidy and worth noticing.
Two things complicate it. The smallest pack sold is two bottles, so the minimum purchase is 120 days of product against that 60-day window. And the label permits up to two capsules daily, at which a bottle is 30 days — so the same purchase is either four months or two, depending on a choice the label leaves entirely to you.
Published in full, as supplied. Read the second one for what it does not say: three ingredients named, and no milligram figure anywhere in either image.
This is the most useful thing on this site, and it is the one thing the label does not tell you. The clinical summary we opened for arginine — the ingredient that occupies two of the three lines in this blend — carries two warnings. Neither is printed on the bottle, mentioned on the listing, or referenced anywhere in the pack supplied to this desk.
The first is an interaction with blood-pressure medicines. The professional section records that arginine “may have additive hypotensive effects” with antihypertensives. The patient-facing section says it in plainer words: “Arginine supplements can also lower blood pressure so taking both at the same time may not be safe.” This is a supplement sold for blood pressure. Many of the people it is sold to already take tablets for it.
The second is about use after a heart attack. Under Warnings: “In patients who had an acute myocardial infarction, arginine supplementation may increase risk of mortality.” The same summary records that oral supplementation after a heart attack “did not improve ejection fraction or vascular stiffness, and may be associated with higher mortality.”
Be fair to the label about what it does say. The caution statement is complete and properly worded: Pregnant or nursing mothers, children under the age of 18 and individuals with a known medical condition should consult a physician before using this or any dietary supplement. High blood pressure is a known medical condition, so that clause is doing real work here. What it does not do is name either of the two specific things above, and a reader who has already consulted a physician about their tablets will not know to go back and ask about these.
So the instruction is simple and it comes before any purchase. If you take prescription blood-pressure medicine, or any other medicine that lowers blood pressure, speak to whoever prescribes it before you buy — not after. Take the panel with you: three ingredient names and a 500 mg total is enough for that conversation. Nothing on this page is a reason to change, reduce or stop anything you have been prescribed.
One of the ten reviews supplied with this product did exactly that. Joyce F., 69, Las Vegas: “I take blood-pressure tablets. Showed the bottle to the clinic first. They said keep the tablets.” That is the most reassuring sentence in the set, and it describes a reader who was better served by her clinic than by the bottle.
Because it is the most practical thing we have to tell you, and because we earn a commission when you buy through this site. A reader who takes the panel to their prescriber before the first capsule has been better served by us than by a sale.
The ring is a 24-hour clock. The bottle itself gives no time of day — only one capsule with an 8 oz glass of water. The shaded band is the morning window the sales FAQ prefers, which is a different document from the label.
One claim sits on the front of this bottle and it is correctly asterisked. Blood Pressure Support*, and the asterisk resolves to the FDA disclaimer printed on the same wrap. The word doing the work is support: lowers blood pressure would be a drug claim and it is not here. Beside it is Premium Formula, which has no definition and claims nothing. Give the front panel its due — this is claim discipline, and most packs this desk reads do not manage it.
Look at the same artwork again and notice the four tiles around the bottle. They read SUPPLEMENT FACTS, 60 CAPSULES, BOTTLE LABEL and FOLLOW LABEL DIRECTIONS, and the strip along the foot repeats three of them. Every one is a pointer back to the packaging. There is nothing wrong with any of it, and there is nothing in any of it either: an artwork headed how it works that names no ingredient, no amount and no mechanism is telling a reader to go and read the bottle, which this page would recommend anyway.
The rest of what is claimed for this product lives somewhere else: on the sales page, in the listing artwork, or on one of twelve seals, none of which names a certifying body, a number or a laboratory. Each claim is taken separately below, with whatever it rests on.
A structure-function claim, properly asterisked. Support is the word keeping it legal — lowers blood pressure would be a drug claim and is not printed. What it rests on is the problem rather than the wording: both amino acids have real human trials behind them, at 3–9 g and 4–24 g a day. The blend is 0.5 g.
Marketing, and worth naming as marketing. Premium has no definition, no standard and no certifying body. It makes no claim, so there is nothing for it to rest on.
Accurate wording for a limited fact, and this desk will say so plainly because the wrong version of this sentence is everywhere. Registration means the facility is on a list the FDA keeps. It is not an inspection, not an endorsement and not approval. No dietary supplement is FDA approved.
The correctly qualified form. It claims assembly in the United States and does not pretend the raw materials were grown or synthesised there. An unqualified Made in USA would be the wrong claim on this product; this is the right one.
A listing seal. No doctor is named anywhere in the pack as the formulator. A physician's name was supplied to this desk, but for a different role — as reviewer of these pages, which he has not read — and we have not printed it there either. An unnamed doctor is a word, not a credential.
Good Manufacturing Practice describes how a facility runs, not what is in this bottle and not whether this batch was tested. No certifying body and no certificate number is named.
Four composition claims on listing seals, none naming a certifying body. The vegetarian one is at least checkable from the panel: hypromellose means the capsule shell is cellulose rather than gelatin, which is the usual reason a capsule fails that test.
Pure names no standard and no contaminant tested for. Natural has no regulatory definition, and is a strange word for two amino acids supplied as manufactured salts. Support guaranteed appears to promise an outcome; the only guarantee described anywhere in the pack is a refund window.
The one seal with a policy behind it. 60 days from purchase, with the sales side also asking for at least 30 days of use. Return shipping is the buyer's cost. Not stated: whether an opened bottle qualifies, whether a multi-pack can be partly returned, or whether a restocking fee applies.
Tap a card to read the quotation and where it came from. Every source was opened by this desk and every quotation is verbatim.
No ingredient photography was supplied with this product, and there is nothing obvious to photograph — the formula is two amino acids as manufactured salts. What was supplied is better: the printed panel and the full wrap.
Two things on this panel are simply correct and worth saying so: the † Daily Value Not Established footnote, because none exists for either amino acid, and the other-ingredients list, which names the capsule shell as hypromellose — cellulose, not gelatin.
This is the most complete label this desk has read. What it does not do is print an amount for any of the three ingredients in the blend.
This is the most complete label this desk has read. Serving size, servings per container, other ingredients, a correct Daily Value footnote, a full caution statement, storage, and a distributor with a town, a postcode and a telephone number. You can take it apart yourself, and most of this site is the result of doing so.
If you are already buying these and are content with a blend, this is a convenient single capsule. Go in knowing the total is 500 mg and compare it with whatever you are taking now — the trials behind both ingredients used grams.
Nine of the ten supplied reviews describe the capsule as the small part of a routine that already contains a walk, a clinic visit or a cuff log. At $0.82 a day on the six-bottle pack, taken that way, it is an inexpensive addition to something else.
Because this product publishes a total and an order, every ingredient can be given a ceiling and every ceiling can be set beside a published trial dose. That is the whole of this site, and it is the kind of decision this label makes possible.
Start here, and speak to whoever prescribes it before you buy. The clinical summary we opened says arginine “may have additive hypotensive effects” with antihypertensives and tells patients that “taking both at the same time may not be safe.” One of the ten supplied reviews is from somebody who showed the bottle to their clinic and was told to keep taking the tablets.
The same summary carries a warning in terms: “In patients who had an acute myocardial infarction, arginine supplementation may increase risk of mortality.” Nothing on this bottle mentions it. If this applies to you, this is a conversation with a cardiologist, not a purchase.
Then this is not a source of it. The blend is 500 mg in total against trials that used 3 to 9 grams of citrulline and 4 to 24 grams of arginine. Even at the label's maximum of two capsules you are at a third of the lower floor, spread across three ingredients.
A proprietary blend will not tell you. You get a total and an order, which is enough for a ceiling and not enough for a figure. If that distinction matters to you — and on a product for blood pressure it reasonably might — this label stops one step short.
The brand's own summary says most people wait three to six weeks, and one of the ten supplied reviews is specifically about this: wanted the home cuff to drop in ten days. It didn't. The pooled trial effects are 4 to 5 mmHg systolic at many times this dose.
The label itself tells you to consult a physician first, and on this it is right.

No trial exists on this combination, so no side-effect profile exists for it either. What exists is a clinical summary for each of the two amino acids in it, and on a product sold for blood pressure one of those summaries matters more than anything else on this page.
Start with what the bottle does well. The caution statement is present, complete and properly worded: Do not exceed recommended dose. Pregnant or nursing mothers, children under the age of 18 and individuals with a known medical condition should consult a physician before using this or any dietary supplement. It is joined by keep out of the reach of children and do not use if safety seal is damaged or missing. That last clause about a known medical condition is doing a great deal of work here, because high blood pressure is one, and it is the thing this product is sold for.
Then the interaction, which is not on the bottle. The clinical summary we opened for arginine records that it “may have additive hypotensive effects” with antihypertensives, and tells patients directly: “Arginine supplements can also lower blood pressure so taking both at the same time may not be safe.” If you take prescription tablets, speak to whoever prescribes them before you buy. Nothing on this page is a reason to change, reduce or stop a prescribed medicine.
Then the warning about heart attack, which is not on the bottle either. Under Warnings, the same summary states: “In patients who had an acute myocardial infarction, arginine supplementation may increase risk of mortality.” It also records that oral supplementation after a heart attack “did not improve ejection fraction or vascular stiffness, and may be associated with higher mortality.” If that applies to you, this is a conversation with a cardiologist rather than a purchase.
And one finding about long-term use, because the six-bottle pack is about a year of it. The same summary notes that while “some studies support the use of arginine in coronary artery and peripheral artery diseases”, “long-term supplementation worsened PAD.” We print it rather than bury it.
On citrulline the summary is quieter and the arithmetic is the point. The pooled analysis found a systolic reduction of 4.10 mmHg at 3 to 9 g a day, with the diastolic result not statistically significant overall. The ceiling here is 500 mg, so this product is nowhere near the amount at which either effect was observed — which cuts both ways, and is not a safety argument for taking it.
Photograph the panel and take it to whoever manages your prescriptions, along with the two sentences above about additive effects and about use after a heart attack. This label makes that conversation easy — three ingredient names, a 500 mg total and a named distributor with a telephone number. What it does not do is tell you to have it.
| Blend line | Ceiling from the order | The doses its trials used | Verdict |
|---|---|---|---|
| L-Citrulline dl-Malate | at most 500 mg | Eight trials; dosage varied from 3 to 9 g/day; systolic −4.10 mmHg; diastolic not significant except at 6 g and above | One sixth of the lowest trial dose, at best |
| L-Arginine (Alpha-Ketoglutarate dihydrate) | at most 250 mg | Eleven trials, 387 participants, 4 to 24 g/d; systolic −5.39 mmHg, diastolic −2.66 mmHg | About one sixteenth of the lowest dose |
| L-Arginine HCL | at most 167 mg | The same eleven trials, 4 to 24 g/d — and this is the second arginine on the same panel | About one twenty-fourth, and less after the HCl |
| The entire blend | 500 mg, or 1 g at two capsules | Against the gentler of the two floors, 3,000 mg a day | One sixth, and one third at the label's maximum |
Ours, and it comes before the label's own instruction for a reason. The clinical summary we opened says arginine “may have additive hypotensive effects” with antihypertensives and that taking both “may not be safe.” Speak to whoever prescribes your tablets before you buy, and keep taking them unless they tell you otherwise.
The label, verbatim: As a dietary supplement, take one (1) capsule daily with an 8 oz. glass of water. The glass of water is the only part of the instruction that is not a choice, and it is on the bottle.
The same sentence continues: May take up to two (2) capsules daily. No reason for the second capsule is published anywhere. It halves the bottle from 60 days to 30 and doubles the cost per day, and 1 g of blend is still a third of the citrulline floor.
The bottle names no time of day. The sales FAQ adds morning before a meal preferred, and gives no reason for it. If mornings do not suit you, the habit matters more than the hour.
Ours. A bottle is 60 days at one a day, so whether this becomes a habit is the whole question. Nine of the ten supplied reviews describe a cue rather than a result — before toast, when the bus app opens, after watering the plants.
The brand's own review summary says most people wait three to six weeks. One of the ten supplied reviews is specifically about expecting faster: wanted the home cuff to drop in ten days. It didn't. The pooled trial effects are 4 to 5 mmHg systolic, at six to twenty-four times this dose.
One capsule a day is the label's serving and 60 capsules is the bottle, so a bottle is 60 days — exactly the refund window. Pick a pack and see where it lands against that window.
Pack size — one bottle is drawn because the arithmetic is worth seeing, but no single bottle is sold; the smallest pack is two
Capsules a day — the label says one and permits up to two, so both are here
All three prices were published in the pack supplied to this desk. There is no single-bottle price, although a single bottle is photographed. The per-day figures assume one capsule a day; at the two the label permits, double them.
Two bottles is a hundred and twenty days at one a day, which is twice the window you have to decide in.
60-day money-back window · no subscription
A hundred and eighty days, about six months, and the pack six of the ten supplied reviews bought.
60-day money-back window · no subscription
Three hundred and sixty days — a year at one a day — bought under a window that closes after sixty.
60-day money-back window · no subscription
The struck-through figures are $358, $537 and $1,074 — which is $179 multiplied by two, three and six. A crossed-out price is a claim about what something used to sell for, and no date is given on which this product sold at $179 a bottle. We print the struck figures because they are on the offer, and this note beside them because they are arithmetic rather than history. · The money-back window runs from purchase, not from delivery · What that actually means
All three prices are published up front, which is worth saying first: $158 for two bottles at $79 each, $177 for three at $59 each, $294 for six at $49 each. Many products in this category publish nothing and defer to the checkout.
The bottle life is unusually tidy. Sixty capsules at the label's one-a-day serving is 60 days, and the refund window is 60 days from purchase. Those line up precisely. At one capsule a day the packs work out at $1.32, $0.98 and $0.82 a day, and $0.82 is a reasonable price for a daily habit.
Then the same sentence on the label cuts the other way. May take up to two (2) capsules daily. At two, every bottle is 30 days and every per-day figure doubles: $2.63, $1.97 and $1.63. Nothing anywhere explains when to take the second capsule, so the price of this product is a range the buyer sets.
And the smallest pack is two bottles. One bottle would have matched the refund window exactly, and one bottle is not sold — though a single-bottle render is supplied in the same artwork as the price list. The minimum purchase is 120 days of product against a 60-day window, and the six-bottle pack is about a year.
The struck-through figures are $358, $537 and $1,074. That is $179 multiplied by two, three and six. A crossed-out price is a claim about what something used to sell for, and no date is given on which this product sold at $179 a bottle. We print the struck figures because they are on the offer, and this sentence beside them because they are arithmetic rather than history.
Shipping. Cost, speed and whether it ships outside the United States are not published anywhere in the pack supplied to us, for any of the three packs. Read the total on the payment screen before you pay.
bloodprildaily.com is a U.S. retail partner for BloodPril, and we earn a commission on orders placed through it. That disclosure is in the footer of every page, and it is why the dose arithmetic is in the first screen of this one rather than the last.
The brief names mybloodpril.online as the sales page for this product. The buy buttons on this site go to the checkout we were given.
+1 (302) 200-3480, with [email protected] by email, handles tracking, changes and refunds on placed orders. This is not the number on the bottle. The bottle prints +1 (507) 448-8190 for the distributor in Lakeland, Florida.
Nothing supplied to this desk names Amazon or any other marketplace as an authorised channel. We have not found one and we accuse nobody of anything — we are telling you what the pack does and does not authorise.
A marketplace sets its own return window, which is not the 60 days described here. If the guarantee is part of why you are buying, buy where the guarantee is.
The individual amounts of the three blend ingredients, the certificate of analysis for lot BP-26/BL-4631, whether an opened bottle qualifies for the refund, and what Support guaranteed guarantees. Ask by email so you have the answers in writing.
The only mark here with a policy behind it. 60 days from purchase, with the sales side also asking for at least 30 days of use before a claim. Return shipping is the buyer's cost and tracking is advised; refunds are quoted at 3–5 business days to credit then 5–10 to reach the card. Not stated: whether an opened bottle qualifies, or whether a six-pack can be partly returned.
This one is worded correctly on the bottle, which this desk does not often get to write: manufactured in an FDA registered facility. Registration means the facility appears on a list the FDA keeps. It is not an inspection, an endorsement or approval, and no dietary supplement is FDA approved.
No doctor is named anywhere in the pack as the formulator of this product. A physician's name was supplied with the pack for a different purpose — to be printed as the medical reviewer of these pages, which he has not read. We have not printed it there either.
Good Manufacturing Practice is about how a facility operates, not about what is in this bottle and not a test of this batch. No certifying body and no certificate number is named.
An honest mark, and it matches the bottle: Made in the USA with globally sourced ingredients. It tells you the raw materials are not all American, which is the kind of thing most listings leave a reader to assume the other way.
No certifying body named. Of the four composition seals this is the hardest to check from the panel, since the amino acids are manufactured and the panel does not say by what route.
Naturally suggests the ingredients never contained gluten rather than that the finished capsule was tested. No threshold, no test and no certifying body is named. If you are coeliac, that distinction is the whole question.
Plausible from the panel — nothing in the three other ingredients is a dairy derivative — but no certifying body is named and no test is described.
This one the panel actually supports. The other-ingredients list names hydroxypropyl methylcellulose (capsule), which is cellulose rather than gelatin — the usual reason a capsule is not vegetarian.
Pure names no standard, no contaminant and no laboratory. The brief gives a certificate reference — BP-4631-26-BL against lot BP-26/BL-4631 — and no certificate was supplied to this desk, so we cannot say what it covers.
Natural has no regulatory definition, and it is a strange word for this formula in particular: the three blend ingredients are amino acids supplied as manufactured salts — a malate, an alpha-ketoglutarate dihydrate and a hydrochloride.
The one seal in this set this desk would ask the seller to withdraw. It reads as a promise about an outcome. The only guarantee described anywhere in the pack is a refund window, and the bottle's own disclaimer says the product is not intended to diagnose, treat, cure or prevent any disease.
Every figure and every word below was supplied to this desk in the same pack as the label artwork. We did not collect these reviews, cannot contact the people named, and cannot confirm that any portrait is a photograph of that person. They are published in full and unedited because hiding them would be the less honest choice, and labelled on every card because presenting them as independent would be the dishonest one.
I commute on the train. Mall walk in the morning. Capsule is extra, not a replacement for the walk. I keep it on the washer. I take it when the ferry horn goes.
I farm a little plot out back. Hotel week. Original bottle, not a baggie. Serving still happened. I keep it by the router. I take it before I walk the mall.
I volunteer at church on Sundays. I don't stack a second circulation bottle. One is enough to remember. I keep it on the piano. I take it before league night.
I bowl league night. That's my reminder. Page said nitric oxide. I don't measure that. I measure whether I took it. I keep it next to the leash. I take it when I unroll the sleeping bag.
I keep horses. Barn first, then the bottle. Spouse handles the cuff log. I handle the capsule. I keep it in the glove box. I take it after I lock the back door.
I do yard work for neighbors. Trash day reminder. Capsule already happened. I keep it on the fridge door. Didn't stack a second brand this time.
I pack lunches for a crew. One capsule before toast. Cuff at the clinic is still the score. I don't skip that visit. I keep it beside the stamp dish. I mark the paper calendar, not an app.
I sit at a sewing machine all day. Head felt heavy in the afternoon. Not gone. Walk plus the capsule. I keep it on the charging pad. I take it when the bus app opens.
I run a food truck window. Wanted the home cuff to drop in ten days. It didn't. Kept the routine. I keep it in the lunch tote. I take it before I open email.
I walk mall laps in the morning. I take blood-pressure tablets. Showed the bottle to the clinic first. They said keep the tablets. I keep it on the workbench. I take it after I water the plants.
All ten reviews, the 4.7 score, the star distribution, the order count and the recommend percentage were supplied to this desk in the same pack as the label artwork. We did not collect them, did not solicit them and have not edited a word of them.
We cannot contact any of the ten people named, cannot confirm that any portrait is a photograph of that person, and cannot confirm that any of them bought or took the product. We publish them because labelling them is more honest than hiding them, not because we can stand behind them.
The supplied distribution gives a weighted mean of 4.30, and the ten published reviews average 4.30 as well. The printed figure is 4.7. We show all three and the arithmetic.
This site publishes no Review and no AggregateRating structured data for these. Google's guidance is that ratings must be sourced directly from users; these were sourced from the seller. Emitting them would put a star rating into search results on the strength of figures we have just told you we cannot verify.
Reserved for reviews this desk collects itself, from buyers who ordered through this site. They are deliberately blank, and will be marked as independently collected when there are any.
With the supply each one actually represents at one capsule a day, which the artwork does not say. Halve every figure if you take the two the label permits.
60 days from purchase is the window. At least 30 days of use is what the sales side asks for before a claim. One bottle at one capsule a day is exactly 60 days, so a single bottle would have matched the window precisely — and the smallest pack sold is two.
It carries the order ID, which is the first thing the desk will ask for, and the date the sixty days run from.
Start the claim on the phone. Do not call the number on the bottle — +1 (507) 448-8190 is the distributor in Lakeland, Florida, not the order desk. Two numbers, two jobs.
Full name, the email address on the order and the order ID, written on a sheet inside the parcel.
To 275 Madison Avenue, Floor 14, New York, NY 10016. Return shipping is the buyer's cost and tracking is advised — an untracked parcel that does not arrive is your loss, and on a six-bottle box that is $294.
Three to five business days for the desk to credit it once the return is processed, then five to ten days for the money to reach the card.
Whether an opened bottle qualifies, whether a multi-pack can be partly returned, and whether a restocking fee applies. None is stated anywhere in the pack. Ask on the phone before you buy six.
| Conflict | What we did |
|---|---|
| The sales page and the panel list the ingredients in different orders | The sales page names L-Arginine first, then L-Citrulline dl-Malate, then L-Arginine HCL. The panel lists L-Citrulline dl-Malate first. On a proprietary blend the order is an order of predominance — it is the only information a reader has about proportions — so this is not a cosmetic difference. We follow the label, because the label wins, and we print both. |
| The sales page named a fourth ingredient the panel folds into a third | The brief records that the FAQ also names L-Arginine Alpha-Ketoglutarate and says to confirm against the label. The panel settles it: AKG is the form of the second arginine, not a separate fourth ingredient. Printed as resolved, with the resolution shown. |
| A one-bottle render exists; no one-bottle price does | The artwork supplied includes a single-bottle photograph. The price list starts at two bottles. We print the render and the absence together rather than quietly dropping the image. |
| The bottle's phone number is not the order desk's | The label prints +1 (507) 448-8190 for the distributor in Lakeland, Florida. Tracking and refunds on placed orders go to +1 (302) 200-3480. Both are published here with what each is for, because calling the wrong one wastes a day. |
| The rating printed is 4.7; the distribution gives 4.30 | 55% five, 28% four, 11% three, 4% two, 2% one works out to 4.30. The ten reviews published average 4.30 as well, which is consistent — it is the 4.7 that does not reconcile with either. We print the recomputation and show the arithmetic. |
| 91% recommend, against 83% who gave four or five stars | The supplied distribution puts four- and five-star reviews at 83% combined. The recommend figure printed beside it is 91%. They may measure different questions; nothing supplied says so. Both are printed, with the gap named. |
| The best-selling pack is not the one the reviewers bought | The supplied summary names six bottles as the top pack. Of the ten reviews in the same pack, six bought three bottles and only three bought six. Printed as the discrepancy it is. |
| Support guaranteed against a disclaimer that guarantees nothing | A listing seal appears to promise an outcome; the bottle says the product is not intended to diagnose, treat, cure or prevent any disease, and the only guarantee described anywhere is a refund. We print the seal and what it actually covers. |
| A dose range with no basis for choosing within it | One capsule daily. May take up to two. We print both and say plainly that nothing supplied explains when to take the second, and we show what each choice does to the bottle life and the price per day. |
| Natural ingredients on a formula of manufactured salts | A malate, an alpha-ketoglutarate dihydrate and a hydrochloride. Printed with what the panel actually says. |
| A review describes a mechanism the label never claims | Luis L.: “Page said nitric oxide. I don't measure that.” Nothing on the bottle supplied to this desk mentions nitric oxide, which means a buyer read it somewhere. Published unedited, and flagged. |
| Twelve seals, zero certificates | Every mark names a quality; none names an issuer, a number or a laboratory. Each seal is printed with what it actually establishes. |
| The brand name ends in a prescription drug suffix | Printed plainly, with the source. We allege no intent, and we do not leave the fact out on a product sold to people who may have an ACE inhibitor in the cupboard. |
2.3 out of 5 — and this is the most frustrating product this desk has reviewed, because it does so much right.<p>The label is the best we have read. A real Supplement Facts panel. A correct Daily Value Not Established footnote. A complete other-ingredients list that tells a vegetarian buyer the capsule is cellulose. A full caution statement. Storage. A named distributor in Lakeland, Florida, with a postcode and a telephone number. An FDA disclaimer correctly asterisked to the one front-panel claim, and a country-of-origin line in its properly qualified form. Those two rows score four and four and a half, and they are earned.</p><p>Then the panel declares one line. A 500 mg proprietary blend of three ingredients, two of which are the same amino acid in different salts. The order of predominance gives each a ceiling — 500, 250 and 167 mg — and those ceilings are what can be set against the research.</p><p>And the research is in grams. Eight trials of L-citrulline at 3 to 9 g a day, pooling to a systolic reduction of 4.10 mmHg. Eleven trials of L-arginine across 387 participants at 4 to 24 g a day, pooling to 5.39 mmHg. This blend is 0.5 g in total. At the label's maximum of two capsules it is 1 g, spread across three lines, against a 3 g floor.</p><p>Two things pull the score below what the label deserves. The product is named with the suffix that marks the ACE inhibitors, and it is sold for blood pressure. And nothing anywhere in the pack mentions that the clinical summary for its second ingredient warns of additive effects with blood-pressure medicines, or that it records a mortality signal after heart attack. One of the ten reviews supplied with this product is from somebody who takes prescription tablets and showed the bottle to their clinic first. That reader was better served by their clinic than by this label, and that is the sentence this score is really about.</p><p>We sell this product and earn when you buy it through this site. That is why this paragraph is at the top of the page rather than the bottom.</p>
The desk reads the label at native resolution, recomputes every figure on it, and opens every source it cites. On this product that was unusually productive, because this label gives a reader more to work with than most. It earns a commission on orders placed through this site, which is why the dose arithmetic is at the top of the page rather than the bottom.
These slots are vacant on purpose. A physician's name was supplied with the product pack and we were asked to print it as the medical reviewer of these pages. He has not read them — they were written after the pack arrived. On a product sold for blood pressure, to readers who may be taking prescription medicine for it, a borrowed medical endorsement is the most dangerous thing a page like this could carry.
Sources are listed in full on every page that makes a claim · Our method and who writes this · Report a correction
Every source above was opened and read. Studies that found nothing are included on purpose.
We ran this product and its category through live search and read what the result pages are made of. Almost every query is defensive — is it a scam, does it really work, is it FDA approved, can I take it with my tablets, why is it called that. Here are the fifteen most common, in the words people type, each answered in one paragraph and linked to the page that shows the working.
Ten were supplied to this desk in the same pack as the label artwork, with photographs. We publish all ten unedited and labelled. We also recomputed the summary: the supplied star distribution works out to 4.30, not the 4.7 printed beside it, and the ten reviews published average 4.30 as well. A second figure does not reconcile either — 91% recommend is printed against a distribution in which 83% gave four or five stars. This site emits no Review or AggregateRating structured data.
All ten, in fullOne line on the panel: a 500 mg proprietary blend of L-citrulline dl-malate, L-arginine alpha-ketoglutarate and L-arginine HCl. No individual amount is printed for any of the three. The order is an order of predominance, so each has a ceiling — at most 500, 250 and 167 mg. The trials behind both amino acids used grams: 3–9 g a day for citrulline, 4–24 g for arginine.
The ceilings, against the trialsNot a question we answer yes or no. This product has the most complete label this desk has read — real panel, full caution statement, storage, other-ingredients list, a named distributor with an address and a phone number, and the FDA disclaimer correctly asterisked. Against that: a proprietary blend that hides all three amounts, a total of 500 mg against trials run in grams, and a brand name that borrows the suffix of a prescription drug class.
Everything we could not verifyNo trial exists on this combination. What can be checked is each ingredient against the dose its own research used, and that check is the whole site. The pooled trials found real but modest effects — systolic down 4.10 mmHg for citrulline and 5.39 mmHg for arginine — at six to twenty-four times the amount this blend can contain.
The dose ladderThe bottle carries a proper caution statement, which many do not. The specific thing to know is an interaction: the clinical summary we opened says arginine “may have additive hypotensive effects” with blood-pressure medicines, and tells patients plainly that “arginine supplements can also lower blood pressure so taking both at the same time may not be safe.”
Interactions, in fullNo, and no supplement is. Supplements go on sale without any FDA approval step. The bottle's own wording is correct — manufactured in an FDA registered facility — and that is a statement about a factory being on a list, not about this product being tested, inspected or approved.
What the seals meanThis is a dietary supplement and it is not a blood-pressure medicine. The bottle says so itself, under the asterisk. If you take prescription tablets, the interaction above is the reason to speak to whoever prescribes them before adding this — not after. One of the ten supplied reviews is from somebody who did exactly that, and reports being told to keep taking the tablets.
Who this is not forBecause of how it is named, this question deserves a straight answer. −pril is the suffix that marks the ACE inhibitors, a class of prescription blood-pressure drugs — lisinopril, ramipril, captopril. This product is a supplement, not an ACE inhibitor, and nothing in it is related to one.
The name, in full$158 for two bottles ($79 each), $177 for three ($59 each) and $294 for six ($49 each). No single bottle is sold, though a one-bottle render appears in the artwork. At one capsule a day those work out at $1.32, $0.98 and $0.82 a day; at the label's maximum of two, double it.
All three packs60 days from purchase, with the sales side also asking for at least 30 days of use first. One bottle at one capsule a day is exactly 60 days, so the window and a bottle match precisely — but the smallest pack is two bottles, which is 120 days.
The window, worked throughBoth have real human evidence, which is unusual on this shelf, and both are modest. Pooled across trials, citrulline lowered systolic pressure by 4.10 mmHg and arginine by 5.39 mmHg. The doses were 3–9 g and 4–24 g a day. This blend is 0.5 g in total.
Both, with the figures60 days at one capsule a day, 30 at two. The label permits either, and says so in the same sentence, so the same bottle is two months or one depending on a choice it leaves to you. No reason to take the second capsule is given anywhere.
How to take itOne blend, 500 mg, three ingredients, no individual weights. It is legal and it is not nothing — the total and the order of predominance are both disclosed, which gives every ingredient a ceiling. It is also the reason nobody outside the company can tell you how much citrulline is in a capsule.
What a blend does and does not hideA Doctor formulated seal appears on the listing. No doctor is named anywhere in the pack as the formulator. A physician's name was supplied to us for a different purpose — to print as the medical reviewer of these pages — and we have not printed that either, because he has not read them.
Why the reviewer line is blank+1 (302) 200-3480 is the order desk, for tracking, changes and refunds, with [email protected] by email. The bottle prints a different number — +1 (507) 448-8190, for the distributor in Lakeland, Florida. For this website rather than an order, write to [email protected].
All contact detailsThese are the questions this product is actually searched with, taken from live search results rather than guessed at. Several of them have answers the brand would rather we did not print.
A dietary supplement in capsule form, sold for blood-pressure support. One bottle holds 60 capsules and the label's suggested use is one capsule daily with an 8 oz glass of water, up to two daily, so a bottle is 60 days or 30. The Supplement Facts panel declares a single line: a 500 mg proprietary blend of L-citrulline dl-malate, L-arginine alpha-ketoglutarate and L-arginine HCl, with no individual amount printed for any of the three.
No. It is a dietary supplement, and its own label says so: the front-panel claim carries an asterisk resolving to not intended to diagnose, treat, cure, or prevent any disease. It is not an ACE inhibitor and contains nothing like one, despite a brand name ending in the suffix that marks that drug class.
We do not know, and we will not guess at an intention. What we can tell you is what the ending means in medicine. The clinical reference we opened states it plainly: ACE inhibitors “most commonly end with the suffix ‘-pril.’ Examples include lisinopril, ramipril, and captopril.” Those are prescription drugs for high blood pressure.<p>This is a dietary supplement sold for blood pressure. It is not one of them. We print the fact because the readers most likely to recognise that ending are the readers this product is aimed at.</p>
A blend gives you a total and an order and withholds the individual weights. Here the total is 500 mg and the order is L-citrulline dl-malate, L-arginine alpha-ketoglutarate, L-arginine HCl.<p>It is not nothing. Ingredients are listed in descending order of predominance, so each has a ceiling: at most 500 mg, 250 mg and 167 mg. It is also not a figure — nobody outside the company can tell you how much citrulline is in a capsule.</p>
From the ordering rule. The first ingredient cannot be more than the whole blend, so its ceiling is 500 mg. The second cannot exceed the first, so it can be at most half the blend: 250 mg. The third at most a third: 167 mg.<p>Every one of those is generous to the product — the real figures are lower, and all three are salts, so part of each weight is malate, ketoglutarate or hydrochloride rather than the amino acid.</p>
Not published. Only the 500 mg blend total is printed. Each ingredient can be bounded from the order — at most 500, 250 and 167 mg — and no further. On a product for blood pressure these are the three numbers a reader most needs, and they are the three the label withholds.
No trial exists on this combination. What can be checked is each ingredient against the dose its own research used, and the answer is the same for all three: the research is in grams and this is in milligrams. Citrulline trials ran at 3–9 g a day, arginine trials at 4–24 g. The whole blend is 0.5 g, and 1 g if you take the two capsules the label permits.
Ask whoever prescribes them before you buy, not after. The clinical summary we opened says arginine “may have additive hypotensive effects” with antihypertensives, and tells patients directly: “Arginine supplements can also lower blood pressure so taking both at the same time may not be safe.”<p>Nothing on this bottle mentions that. One of the ten reviews supplied with this product is from somebody who takes prescription tablets, showed the bottle to her clinic first, and reports being told to keep taking them.</p>
Yes, and specifically. The same clinical summary carries this under Warnings: “In patients who had an acute myocardial infarction, arginine supplementation may increase risk of mortality.” It also records that oral supplementation after a heart attack “did not improve ejection fraction or vascular stiffness, and may be associated with higher mortality.”<p>Nothing anywhere in this product's pack mentions it. If this applies to you, this is a conversation with a cardiologist rather than a purchase.</p>
Nothing supplied to this desk tells you how to choose, which is the oddest gap on an otherwise careful label. The choice is not trivial: at one a day a bottle is 60 days and the six-pack is about a year; at two it is 30 days and six months, and the cost per day doubles.<p>What can be said is that even two capsules is 1 g of blend against a 3 g floor in the citrulline trials, so doubling does not bring this into the studied range.</p>
$158 for two bottles ($79 each), $177 for three ($59 each) and $294 for six ($49 each), against struck figures of $358, $537 and $1,074. No single bottle is sold. Confirm at the live checkout.
At one capsule a day: $1.32, $0.98 and $0.82 for the two-, three- and six-bottle packs. At the two capsules the label permits, double each: $2.63, $1.97 and $1.63.

Yes, and a lot of it. This is the most complete label this desk has read: a real panel, a correct Daily Value footnote, a full other-ingredients list, a proper caution statement, storage, a named distributor with an address and a phone number, and the FDA disclaimer correctly asterisked to the front-panel claim. The country-of-origin wording is the properly qualified form. Two of the ten score rows are four and above because of it.
Nobody, and the slot is left visibly empty rather than filled. See above for why.
One bottle is 60 capsules, which at one a day is 60 days — exactly the length of the refund window. No single bottle is sold, so the smallest commitment is two bottles: $158, $1.32 a day, and 120 days of a product whose three individual amounts are not printed.
The struck-through figures are $358, $537 and $1,074 — which is $179 multiplied by two, three and six. A crossed-out price is a claim about what something used to sell for, and no date is given on which this product sold at $179 a bottle. We print the struck figures because they are on the offer, and this note beside them because they are arithmetic rather than history. · window runs from purchase · no subscription · not for under 18, pregnancy or nursingWritten and fact-checked by The Bloodprildaily Editorial Desk, last updated October 12, 2026.
