N-ACETYL-L-GLUTAMINE (NAG) is a form of the amino acid L-glutamine that is more easily absorbed by the body. NAG acts as a precursor to glutathione, which is a natural antioxidant in the body. Glutathione can help protect cells from oxidative stress, as well as affect muscle and immune system recovery. NAG may also have potential benefits for the digestive system. Because it acts as a source of energy for intestinal cells, which can affect the regeneration of the intestinal mucosa and reduce inflammation. What’s more, NAG can also increase growth hormone production. Which can be beneficial for athletes who want to increase their muscle mass and strength.

Dosage: from 2 to 10 g per day.
