Additional Information

As key players on the amino acid team, L-Arginine & L-Ornithine needs are elevated in times of intense physical stress. L-Arginine acts as an antioxidant to prevent free radicals from damaging cells, and is also a precursor to nitric oxide, promoting healthy dilation of blood vessels, blood flow, and blood lipid levels. L-Ornithine, a precursor to L-Arginine, may help promote lean body mass anabolism. Alpha lipoic acid is also an antioxidant, useful for fighting free radicals generated by intense physical activity, thus aiding muscle recovery and repair.
