L-Glutamine, the free form amino acid, is the single most abundant amino acid present in skeletal muscle. L-Glutamine may support muscle tissue by limiting the degradation of protein through nitrogen retention, glycogen synthesis, and protein synthesis. L-Glutamin may also assist in the fueling and detoxifying of the brain. Thus, L-Glutamine has been dubbed the thinker's amino. L-Glutamine's muscle and brain tissue supporting qualities have made L-Glutamine an invaluable addition to an athlete's regimen.Supplement Facts: Serving Size: 1 Teaspoon Servings Per Container: 222 Amount Per Serving: L-Glutamine: 4500mg
