BloodPril®: daily amino acid support for healthy blood pressure
One capsule a day of L-arginine and L-citrulline, the building blocks of nitric oxide, which helps blood vessels relax.
Quick answer: BloodPril is a capsule supplement with a 500 mg blend of L-Citrulline DL-Malate, L-Arginine AKG and L-Arginine HCl. The label says 1 capsule daily, up to 2. It supports healthy circulation and blood pressure alongside medical care; it is not a replacement for blood pressure medicine. It costs $49 to $79 a bottle with a 60-day guarantee.
How BloodPril is made, in the brand's words
The label says BloodPril is made in the USA with globally sourced ingredients and manufactured in an FDA-registered facility. The brand also states GMP certification. We report these statements rather than verify them.
You will not see an "FDA approved" badge here. The FDA registers facilities; it does not approve supplements.

Amino acid formula
What is BloodPril?
BloodPril (printed as Blood Pril on the label) is a white bottle of 60 vegetarian capsules labelled "Blood Pressure Support, Premium Formula". It is a single-purpose formula: three forms of two amino acids, arginine and citrulline.
These amino acids feed the nitric oxide pathway. Nitric oxide tells the muscle in blood vessel walls to relax, which widens vessels and eases blood flow. That is the whole idea behind the product.
What the label does not show is how much of each amino acid is in the 500 mg blend. See the BloodPril ingredients page.
Read the full BloodPril explainerHow does BloodPril work?
It targets one pathway: nitric oxide and blood vessel relaxation.
Take one capsule
With an 8 oz glass of water, at the same time each day.
Arginine becomes nitric oxide
Cells lining blood vessels turn arginine into nitric oxide; citrulline is recycled into more arginine by the kidneys.
Vessels relax over weeks
Any effect builds with daily use. Track your readings at home and share them with your doctor.
Good to know: if you take blood pressure medicine, nitrates or ED drugs, talk to your doctor first, because these amino acids act on the same blood-vessel pathway. Never stop a prescribed medicine on your own. More on the how to use page.

What is inside BloodPril?
This is the Supplement Facts panel printed on the BloodPril label.
Supplement Facts
Honest note: the whole blend is 500 mg per capsule (up to 1,000 mg at 2 capsules). Blood pressure studies used several grams of arginine or citrulline a day. Treat the research links as background on each ingredient, not proof that BloodPril works the same way.
L-Arginine HCl
An amino acid the body uses to make nitric oxide, the signal that relaxes blood vessel walls. A meta-analysis of trials found modest blood pressure reductions, but at 4 to 24 grams a day.
L-arginine research on PubMedL-Arginine AKG
Arginine bound to alpha-ketoglutarate, popular in sports formulas. It adds to the arginine supply; there is little blood pressure research on this form specifically.
Arginine AKG research on PubMedL-Citrulline DL-Malate
The kidneys convert citrulline into arginine, and it raises blood arginine more reliably than arginine itself. Blood pressure studies usually used 3 to 6 grams a day.
L-citrulline research on PubMed
