Bloodpril Reviews: The Things This Seller Gets Right
It would be dishonest to leave this review at criticism. Bloodpril avoids more standard tactics than almost any product we have covered, and readers deserve to know which parts they can trust.
Published blend total, honest pricing, correct regulatory language, generous guarantee, accurate mechanism, and advice against its own revenue interest.
It publishes the number
Start here, because it is the rarest thing on the list. A proprietary blend legally needs to declare only its total weight, and many brands do not even do that.
Bloodpril prints 500 mg. That figure is the basis of every criticism on this site — which is a strange thing to credit a seller for, and entirely fair. A company that gives buyers the means to check its product has done something most of its competitors deliberately avoid.
The page avoids the standard tactics
No invented anchor price. No crossed-out “regular” figure, no manufactured savings. Every total multiplies correctly.
No countdown timer, no stock counter. Urgency devices exist to stop you running the checks a careful buyer would otherwise run — here, the pharmacist conversation the nitrate interaction warrants.
“FDA-registered” used correctly. The page says the facility is FDA-registered, which is accurate, rather than claiming the product is FDA-approved, which would be false. A great many competitors print the false version.
Nitrates named specifically in the FAQ rather than hidden behind generic boilerplate.
No subscription, stated plainly, in a category where unwanted rebills are the most common complaint.

And it argues against its own interest
Two things stand out here.
The mechanism is described accurately. The explanation of why oral citrulline outperforms oral arginine — arginase, first-pass metabolism, kidney conversion — is correct, non-obvious and better than most nutrition writing aimed at consumers. They could have written vague pseudo-science instead.
It tells you the cheapest package fits the guarantee. The page notes that the two-bottle option is a 60-day supply aligning exactly with the 60-day evaluation window. That is accurate, useful, and steers a buyer toward the smallest order.
None of which changes the conclusion: a well-presented product built on a real mechanism, supplying a few percent of the dose that mechanism was demonstrated at. But the criticism lands differently against a seller who has clearly tried to get things right, and we would rather ask this brand to raise its dose than write off the category.
The trial that was stopped early
This is the single most important piece of context on this site for anyone with established heart disease, and it appears on no page selling L-arginine.
A randomised controlled trial investigated L-arginine supplementation in patients recovering from myocardial infarction. It was terminated early because more deaths occurred in the arginine group than in the placebo group.
The finding has been debated in the years since and has never been fully explained. Proposed mechanisms include effects on nitric oxide handling in already-damaged vasculature. It is one trial, in a specific population, and it should not be over-generalised to healthy adults.
But it has also never been overturned, and it concerns exactly the population most likely to be buying a cardiovascular supplement. If you have had a heart attack, this makes an arginine product a cardiologist conversation rather than a personal choice.
Independent background reading, none of it selling anything: the American Heart Association on high blood pressure, NHLBI on high blood pressure and PubMed. For the applied version of this on our own pages, see how the formula is meant to work or the Bloodpril official website reference.
What we would do
Take the ingredient list to a pharmacist before ordering if you take anything cardiovascular, and to a cardiologist if you have had a heart attack. Buy a validated upper-arm monitor and record twice-daily readings for a fortnight before your first capsule so you have a baseline rather than an impression. Choose the two-bottle package, since 60 days of product against a 60-day guarantee is the only combination that keeps your whole spend inside the refund window. Diarise day 50 on the day you order.
Frequently asked
A 500 mg proprietary amino acid blend of L-Arginine HCL, L-Arginine Alpha-Ketoglutarate and L-Citrulline Malate, plus gelatin, rice flour and magnesium stearate as non-actives. Two capsules daily, 60 per bottle.
The blend total is — 500 mg per serving, which is more than most competitors publish. The split between the three amino acids is not.
L-arginine blood pressure trials used 6,000–12,000 mg daily and L-citrulline trials used 3,000–6,000 mg. A 500 mg blend is roughly 3–6% of that combined range.
Two bottles $158 ($79 each) plus $9.99 shipping, three bottles $207 ($69 each) with free US shipping and six bonus guides, or six bottles $294 ($49 each) with the same extras.
Disclaimer. This formula acts on the nitric oxide pathway — the same pathway as nitrate medicines such as nitroglycerin and isosorbide, and as PDE5 inhibitors such as sildenafil. Take the ingredient list to a pharmacist before ordering if you take any cardiovascular medication, and to a cardiologist if you have had a heart attack.
