Arginine

Optimal dose 100-200 mg/day

This key amino acid is a "double edged sword." It:

• May help raise growth hormone, which helps muscles and keeps people young.
• Can raise nitric oxide, which can help male sexual function (Viagra increases nitric oxide production).

The main concern with arginine is that it also promotes the growth of some viruses in the herpes family. Therefore only low levels should be used in supplements.
