L-arginine is an amino acid that helps the body build protein.

L-arginine is involved in areas of human biochemistry, including ammonia detoxification, hormone secretion, and immune modulation.

It is a key building block for maintaining healthy tissue and bones. In addition to that, L-arginine serves as a precursor to nitric oxide, which is needed to help the arterial system retain youthful elasticity.

Since it can improve blood flow and supports blood vessel size and health, L-arginine might be beneficial for your cardiovascular health. The Mayo Clinic says that it might help relieve occasional discomfort.

For those who have already-healthy blood pressure, an L-arginine supplement can help to maintain it and continue to promote healthy endothelial function and vascular tone. Preclinical studies suggest that arginine supplementation can help especially if you're sensitive to salt. This is why L-arginine is a common supplement for supporting already-healthy blood pressure.

Testosterone is a key hormone for men, and levels tend to dip with older men: Affecting everything from muscle strength to sexual response. To support healthy testosterone levels, L-arginine supplementation might help "stay in the game." Animal studies reveal that arginine can help promote healthy testosterone levels. More specifically, it can promote secretion of luteinizing hormone (LH), which the testes use to produce testosterone.
