Enhances other supplements for endurance
by Noah H.

I take this supplement on the recommendation of a coach at my gym. NAC is an amino acid that helps the body best use protein to feed the large muscles and provide better circulation to the cells so that athletes reach optimum performance levels and increase their total muscle weight and performance. He considered this an "enhancer" supplement to go hand in hand with other sports nutritional supplements, such as creatine, glutamine or ultra high or whey protein additions, which are difficult for the body to fully metabolize. Working together, these supplements, especially the antioxidants, build denser muscle mass and provide fuel maintenance for the muscles.
