How To Take BloodPril
One capsule with 8 oz of water, up to two. The first instruction on this page is not the label's: if you take blood-pressure medicine, speak to whoever prescribes it before you buy.
Written by the BloodPril editorial team·Last updated October 12, 2026·How this page was checked
If you take prescription blood-pressure medicine, speak to whoever prescribes it before you buy. That comes before the label's own instruction because the clinical summary we opened for arginine says it may have additive hypotensive effects with antihypertensives, and tells patients that arginine supplements can also lower blood pressure so taking both at the same time may not be safe. Nothing on this bottle mentions it. Nothing on this page is a reason to change, reduce or stop a prescribed medicine. The directions, verbatim: as a dietary supplement, take one capsule daily with an 8 oz glass of water, and you may take up to two capsules daily. The bottle names no time of day; the sales FAQ adds that morning before a meal is preferred, and gives no reason. Nothing published explains when to take the second capsule, and the choice is not trivial: at one a day a bottle is 60 days and the six-pack about a year, while at two it is 30 days, the six-pack six months, and the cost per day doubles. Give it weeks rather than days.
How to take it, as the label describes
If you take blood-pressure medicine, ask the prescriber first
Ours, and it comes before the label's own words for a reason. The clinical summary we opened records that 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.” Nothing on this bottle mentions it. Speak to whoever prescribes your tablets before you buy, and keep taking them unless they tell you otherwise.
One capsule, with an 8 oz glass of water
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.
Up to two, and nothing tells you how to choose
The same sentence continues: May take up to two (2) capsules daily. No reason for the second capsule is published anywhere in the pack supplied to this desk.
Morning before a meal, if you follow the sales FAQ
The bottle names no time of day at all — only the water. 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.
Attach it to something you already do
Ours. Nine of the ten supplied reviews describe a cue rather than a result — before toast, when the bus app opens, after watering the plants. On a 60-day bottle, whether this becomes a habit is the whole question.
Give it weeks, not days
The brand's own summary says most people wait three to six weeks, and one of the ten reviews is specifically about expecting faster: wanted the home cuff to drop in ten days. It didn't.
Work out your own supply
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.
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
Before the first capsule: if you take tablets for this
This page puts the safety step first because the bottle does not. The caution statement on the label is complete and properly worded — individuals with a known medical condition should consult a physician before using this or any dietary supplement — and high blood pressure is a known medical condition. What it does not do is name the specific reason.
The reason is in the clinical summary for arginine, which occupies two of the three lines in this blend. On interactions with antihypertensives it records that arginine “may have additive hypotensive effects”. For patients it puts it plainly: “Arginine supplements can also lower blood pressure so taking both at the same time may not be safe.”
The same page carries a second warning. Under Warnings: “In patients who had an acute myocardial infarction, arginine supplementation may increase risk of mortality.” If you have had a heart attack, this is a conversation with a cardiologist rather than a purchase.
So the instruction is this. If you take any medicine that lowers blood pressure, speak to whoever prescribes it before you buy, and take the panel with you. 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 precisely that. Joyce F.: “I take blood-pressure tablets. Showed the bottle to the clinic first. They said keep the tablets.”
Pregnant and nursing mothers, and anyone under 18. That is the bottle's own caution statement, and on this it is right.
One capsule or two, and what it does to the bottle
The label permits either in a single sentence and gives no basis for choosing. Take one (1) capsule daily with an 8 oz. glass of water. May take up to two (2) capsules daily. That is the whole of it. This is the oddest gap on an otherwise careful label, because the choice changes more than anything else a buyer decides.
At one capsule a day, 60 capsules is 60 days, which matches the 60-day refund window exactly. Two bottles is 120 days, three is six months, six is about a year. The per-day figures are $1.32, $0.98 and $0.82.
At two capsules a day, every one of those halves and every price doubles. A bottle is 30 days. Two bottles is two months, three is three, six is six. The per-day figures become $2.63, $1.97 and $1.63. Nothing in the pack explains when the second capsule is appropriate, so the cost of this product is a range the buyer sets without guidance.
What can be said about the dose itself. Two capsules is 1 g of blend, against a 3 g floor in the citrulline trials and a 4 g floor in the arginine trials. Doubling does not bring this product into the studied range. The label also says do not exceed recommended dose, and two is that maximum.
And a missed day. Nothing supplied addresses one. On a once-daily capsule the practical answer is to take it the next morning rather than double up.
Weeks not days, and what to keep measuring
Give this weeks rather than days. The brand's own review summary says most people wait three to six weeks, and 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 behind the two amino acids are 4 to 5 mmHg systolic, at six to twenty-four times the amount this blend can contain.
Note what that does to the refund window. The window is 60 days from purchase and the sales side asks for at least 30 days of use before a claim. At six weeks you are 42 days in with 18 days left to decide. One bottle at one capsule a day is exactly 60 days, so a single bottle would have matched the decision period precisely — and the smallest pack sold is two.
Keep whatever you were already measuring. Blood pressure is a number you cannot feel, which is the whole reason a cuff exists. Two of the ten supplied reviews mention one — a clinic visit kept as the score, and a log a spouse keeps. On a product at this dose, whether anyone is measuring matters more than the capsule does.
With other supplements? The thing to check is overlap. If you already take L-citrulline or L-arginine separately, this blend adds an unknown amount of both to whatever you are on, because no individual weight is printed — only the 500 mg total and the order. Take both labels to the same conversation.
Storage, which the bottle does cover. Keep away from heat, light, and humidity to preserve freshness. Store in a cool, dry place. No temperature range is given.

Why the serving size is the line everything hangs on
It looks like the least interesting line on a Supplement Facts panel, and it is the one that makes every other line usable.
An amount on a panel is an amount per serving, which is why the serving size is the first line of the box. This panel prints both halves of that — Serving Size: 1 capsule and Servings Per Container: 60 — and the directions agree with them: “take one (1) capsule daily with an 8 oz. glass of water. May take up to two (2) capsules daily.” What the panel has nothing to be per is an individual amount, because the dietary half of it is one blended row of 500 mg and not one of the three ingredients carries a weight.
It is also what turns a container into a supply, and here the label prints the servings count itself. 60 capsules at one a day is 60 days, exactly the length of the refund window; at two a day it is 30.
And it is what makes a price comparable. A cost per day is a price divided by days, and here the days are known exactly: $1.32, $0.98 and $0.82 a day at one capsule, and double at two. Write that figure down before you decide.
Everything downstream of the serving size is calculable. The one thing missing sits inside it: how the 500 mg is divided between three names, two of which are the same amino acid.
Look at it before you look at anything on this site. Whatever is printed on your bottle is the instruction, and if it differs from what we have published, the bottle wins. Two things are worth doing that we could not: ask the desk whether the certificate behind reference BP-4631-26-BL can be sent to you, and — if you take a blood-pressure medicine — show the panel to your prescriber first.

How To Take BloodPril: common questions
How do I take it?
The label: As a dietary supplement, take one (1) capsule daily with an 8 oz. glass of water. May take up to two (2) capsules daily. The sales FAQ adds morning before a meal preferred.
One capsule or two?
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>
When should I take it?
The sales FAQ says morning before a meal preferred. The bottle itself gives no time of day, only the 8 oz of water. No reason for the morning preference is published.
What if I miss a day?
Nothing supplied addresses a missed serving. On a once-daily capsule the practical answer is to take it the next morning and carry on. Nine of the ten supplied reviews describe tying it to something that already happens, which is the part that makes a two-month habit survive.
How long should I take it before deciding?
The brand asks for 30 days of use before a refund claim and says most people wait three to six weeks. The window is 60 days from purchase. At one capsule a day, one bottle is exactly 60 days — so a single bottle would have matched the decision period precisely. The smallest pack sold is two.
If you are going to try BloodPril, try it this way
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 nursing
