Bloodpril Get Reviewed: Premium Blood Pressure Capsule, Graded Ingredient by Ingredient
Three actives, three grades. Each scored on two separate questions: does the ingredient have human evidence for blood pressure specifically, and can a 500 mg shared blend deliver it?
One ingredient scores well on evidence. None scores well on delivery, because they share 500 mg.
L-Citrulline Malate — the best of the three
Evidence: good. Delivery: constrained. This is the ingredient that justifies the formula’s design. Its value is counter-intuitive and the seller explains it correctly: oral citrulline raises plasma arginine more effectively than oral arginine does, because it is not a substrate for the arginase enzymes that destroy arginine in the gut wall and liver. It converts to arginine in the kidneys instead.
Randomised trials have reported modest blood pressure reductions and improvements in arterial stiffness measures, generally over six to twelve weeks. Researched dose: 3,000–6,000 mg daily. Even if the entire 500 mg blend were pure citrulline, it would sit at roughly a sixth of the low end.
L-Arginine HCL — right substrate, wrong amount
Evidence: real but dose-dependent. Delivery: poor. This is the direct substrate that eNOS converts into nitric oxide, so the mechanism is as direct as it gets. The problem is bioavailability: most of an oral dose is degraded before reaching circulation, which is why the blood pressure literature clusters at 6,000–12,000 mg daily and why studies below roughly 4 g tend to show little.
There is also the safety context that no page selling arginine mentions: a randomised trial in patients recovering from myocardial infarction was halted early over a mortality signal. One trial, one population, never explained — and never overturned.

L-Arginine AKG — the weakest case
Evidence: thin for this purpose. Delivery: unknown. Arginine bonded to alpha-ketoglutarate, a Krebs cycle intermediate argued to improve cellular uptake. The chemistry is plausible and AKG contributes to energy metabolism in its own right.
But nearly all AAKG research sits in sports nutrition — exercise performance, blood flow during training, recovery — at 3–6 g daily, with mixed results. There is very little blood-pressure-specific human data on this form. Claiming it delivers superior arginine for cardiovascular purposes borrows from a different research context.
The grade overall: sensible ingredient selection, genuinely good reasoning behind the citrulline inclusion, and a total dose that puts all three below the level at which their own evidence base was generated.
Pricing that does not need correcting
Reviewing pricing in this category usually means dismantling a fictional reference price. Not here, and that deserves saying plainly.
Two bottles at $79 each is $158 plus $9.99 shipping. Three bottles at $69 each is $207 with free shipping. Six bottles at $49 each is $294 with free shipping. Every total multiplies correctly. There is no crossed-out anchor price, no invented “regular” figure nobody has paid, and no “you save $780” calculated from a number that does not exist.
There is also no countdown timer and no stock counter. Urgency devices exist specifically to stop you running the checks a careful buyer would otherwise run — including, for this product, the pharmacist conversation the nitrate interaction warrants.
Per day the packages work out at roughly $2.63 (plus shipping), $2.30 and $1.63. Those are the numbers to compare against what 500 mg of blend is worth.

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.
