L-Arginine
(Powder, Tablets and Capsules)
L-arginine is converted in the body into a chemical called nitric oxide.
Nitric oxide causes blood vessels to open wider for improved blood flow.
L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body.
It can be made in a lab and used in supplements.
