L-Glutamine is the most abundant amino acid in the body and plays an important role in muscle recovery and muscle protein development. During periods of intense exercise, L-Glutamine levels can be depleted which may limit protein synthesis. Each serving of Glutamine provides 5 grams of 100% micronized L-Glutamine, which may help support recovery post-exercise. Also, Glutamine is unflavored, so you can add to your post-workout protein shake or favorite beverage.
