L-Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production. It is an important precursor of Nitric Oxide (NO) and thus plays a role in the dilation of blood vessels.

This product has twice the L-Arginine (1,000 mg per tablet) as in our regular strength product (500 mg per capsule).

The L-Arginine used in this product is Pharmaceutical Grade.

Natural color variation may occur in this product.
