BloodPril ingredients: the label, and the dose question
Three amino acid compounds in one blend. Here is what each is for, what the research used, and why the total matters as much as the names.
BloodPril's label lists a single 500 mg proprietary blend of L-arginine HCl, L-arginine alpha-ketoglutarate and L-citrulline malate, plus gelatin, rice flour and magnesium stearate as the inactive ingredients. The amount of each amino acid inside the blend is not disclosed.

L-Arginine HCl
The body's direct raw material for nitric oxide, and the most-studied amino acid for circulation support. A significant share of oral arginine is broken down before it reaches circulation, which is why trials examining blood pressure have generally used several grams a day rather than modest amounts.
L-Arginine Alpha-Ketoglutarate
A second arginine form, usually shortened to AAKG. It comes from sports nutrition, where it has mostly been examined for blood flow during exercise rather than for resting blood pressure. Treat it as additional arginine rather than as a third mechanism.
L-Citrulline Malate
Citrulline converts into arginine in the kidneys, and some research suggests this indirect route raises arginine levels more reliably than arginine itself. Published work on systolic blood pressure has tended to use around six grams daily, with higher amounts also affecting diastolic readings.

See today's priceThe dose question, in plain terms
Three compounds. One 500 mg total. No individual amounts. Research doses measured in grams.
Put those four facts together and the conclusion is straightforward: this is a daily maintenance amount, not a research dose. Even if the entire 500 mg were citrulline — which it is not, since it is shared three ways — it would still be a twelfth of the amount used in the citrulline blood pressure work.
We are stating this clearly because the alternative is letting you assume otherwise. The ingredient selection here is genuinely better than most of the category; the amount is the part to be realistic about. Our guide to how proprietary blends work explains why labels are written this way.
The inactive ingredients
Gelatin, rice flour, magnesium stearate. Two things worth noting. The gelatin capsule means this is not vegetarian or vegan. And the short inactive list is a genuine positive — no colourings, no unnecessary fillers.
If you take medication, read this before ordering
Take the bottle to your pharmacist. Arginine and citrulline can add to the effect of blood pressure medication, and the combination with nitrates is a specific concern. People with kidney disease should also check first, since the kidneys do the citrulline conversion. This is a two-minute conversation over a counter and it is the single most useful thing you can do before starting.
