L-Arginine is a semi-essential amino acid synthesized by
the body from ornithine. It supports protein synthesis because
it is involved in the transport and storage of nitrogen.
L-Arginine is important for proper physical performance
because it is used by the body to produce creatine. L-Arginine
1000 is from free base arginine, which is 17% more potent
than arginine HCI (hydrochloride).
