Naked Glutamine has only one ingredient: L-Glutamine naturally fermented from plant sources. Glutamine is the most abundant amino acid found in your muscles and blood, but it may be depleted during prolonged exercise. Supplementing with L-Glutamine can improve exercise endurance and help preserve muscle mass. 

Naked Glutamine is free of any artificial additives. Don’t let the supplement industry fool you; additives are for their bottom line, not your health. Independent third-party tested for heavy metals.
