L-Glutamine is the most abundant single amino acid which comprises 61% of the free intracellular amino acid pool (most abundant amino acid in muscle tissue).

Benefits of L-Glutamine:

L-Glutamine plays key roles in protein metabolism, cell volumizing, and anti-catabolism. Glutamine also increases your ability to secrete Human Growth Hormone, which helps metabolize body fat and support new muscle growth. Glutamine's anti-catabolism ability prevents the breakdown of your muscles. This is especially useful for people 'cutting down'. Especially during summer when you're trying to get rid of some body fat without losing any muscle.

L-Glutamine is needed throughout your body for optimal performance. Your small intestines requires the most Glutamine in your body, and your immune system also needs Glutamine Because Glutamine levels deplete during workouts, bodybuilders are more susceptible to illnesses - this is why L-Glutamine supplementation is so important, not necessarily to gain more muscle, but for the 'maintenance' effects of L-Glutamine.

L-Glutamine supplementation promotes a positive nitrogen balance and prevents the loss of muscle. Recent studies have shown that taking just 2 grams of L-Glutamine can increase growth hormone levels by 400%.

Bodybuilders should take 10 to 15 grams of L-Glutamine a day - supplementing it 2 to 3 times daily, with each serving at around 5 grams. You should also know that you may already be getting some L-Glutamine in your diet from other supplements you're taking. Many protein supplements already have some L-Glutamine mixed into it, so read the labels to know for sure. Best times to take L-Glutamine powder is in the morning, after a workout, and at night before bed time.
