An amino acid the body converts toward nitric oxide production, relevant to blood flow and vascular tone.
L-Citrulline is a naturally occurring amino acid that the body converts into L-arginine and then nitric oxide, a molecule that helps relax and widen blood vessels.
Research on L-Citrulline for circulation and blood pressure support has generally used doses in the range of several grams daily. Because Vasoryn's entire 570 mg blend is shared across six ingredients, the actual citrulline content here is almost certainly well below doses studied for this specific effect.
Research on this ingredient alone has generally used up to 3,000 mg, for context — but Vasoryn's label does not disclose how much of the 570 mg blend this ingredient makes up.
This describes general research on L-Citrulline itself, not the finished Vasoryn product, which hasn't been the subject of its own clinical trial. See the full label breakdown for more.
