If you undertake power sports, or endurance sports (e.g. running, cycling) the benefits of supplementing your diet with L-Glutamine are many. Research has demonstrated that high levels of stress to the body (for example during intense or endurance exercise, sports and athletics) can massively deplete this vital amino acid. By supplementing your diet with L-Glutamine you can rebalance your levels of this amino acid and help gain lean muscle, reduce muscle damage and aid faster recovery. Increasing GH in the body will aid muscle growth and metabolise body fat. Recent studies show that taking just 2 grams of L-Glutamine daily can increase GH levels by 400%.
