The BloodPril™ label lists three active ingredients as one 500 mg blend: L-Citrulline DL-Malate, L-Arginine (Alpha-Ketoglutarate) and L-Arginine HCL. Per-ingredient amounts are not published. Three other ingredients form the capsule and fillers: hydroxypropyl methylcellulose, microcrystalline cellulose and magnesium stearate.

- Three amino acid ingredients are listed together as a single 500 mg blend.
- Per-ingredient amounts are not published, so none are quoted here.
- The names look technical but each one describes a form of an amino acid.
- Three additional ingredients make up the capsule and its fillers.
Start with the structure of the panel
Supplement labels have a predictable layout. The supplement facts panel shows what is in a serving, and a separate line at the bottom lists the other ingredients. For this capsule, the panel presents one blend of 500 mg, and the three names inside it are written in the order they appear on the bottle.
The brand lists the blend as a total rather than splitting it into individual weights. That is a common labeling choice, and it means the honest way to describe the lineup is by name and type, not by guessed numbers.
Ingredient one: L-Citrulline DL-Malate
Citrulline is an amino acid, and the "L" tells you which of two mirror-image shapes the molecule takes; the L-form is the one used in nutrition and found in food. "DL-Malate" describes a pairing with malic acid, a compound that also turns up in fruit. In plain terms, the name tells you the amino acid has been matched with a partner molecule, a style of ingredient chemistry that makes it easier to blend and handle in a capsule.
If you want to see how this ingredient is presented across the rest of the brand's material, the BloodPril formula page lists it alongside the others.

Arginine is another amino acid and, like citrulline, is found in everyday protein foods. The words in parentheses describe its partner: alpha-ketoglutarate is a compound the body makes naturally as part of ordinary cell chemistry. Seeing a partner molecule in brackets is simply how labels signal that the arginine has been paired with something else in this particular form.
The key takeaway for a shopper is that two of the three ingredients are both arginine, written in two different forms.
Ingredient three: L-Arginine HCL
The third ingredient is arginine again, this time paired with hydrochloric acid, which is what "HCL" stands for. This pairing is a familiar format in the supplement world because it produces a stable, easily handled powder. It is the same amino acid base as ingredient two, offered in a different form.
Reading the three names together, you can see the lineup is really a small family: one citrulline form and two arginine forms. That is a tidy, focused formula, and it explains why the brand describes the product simply as an amino acid capsule.
The other ingredients, briefly
Beneath the blend, the label lists hydroxypropyl methylcellulose, which is the plant-based material of the capsule shell, plus microcrystalline cellulose and magnesium stearate, which are common supporting ingredients used in capsule making. The brand also states the product is non-GMO, stimulant-free, and made in the USA in an FDA-registered facility following GMP standards.
For a deeper dive into those fillers, the shell and the other supporting ingredients each have their own explainer on this blog, and the what is it page gives the wider overview.
How to use this when you shop
A label is easier to read when you know the pattern, and a quick habit helps: read the panel once when the bottle arrives, then keep a photo of it on your phone. That way you can answer any question about the formula in seconds, and you can compare it with any other label you come across, using the same three checks each time. Look for the total blend weight, check the order of the names, and read the other ingredients line for the capsule materials. The Office of Dietary Supplements publishes friendly guides to reading supplement facts panels if you want to build the skill further.
