L-Glutamine is a non-essential amino acid that is naturally produced by the body and plays an important role in metabolic function.* It is used by the body to fuel the cells and is the most common amino acid found in the human body. L-Glutamine is most commonly used by athletes and bodybuilders as a part of a pre-workout regimen. Glutamine is also used as a pre workout supplement aid for exercise recovery and promotes athletic endurance. It plays a key role in maintaining a healthy intestinal lining and increases the rate of absorption of nutrients into your bloodstream. It also plays a role in the maintenance of muscle mass and immune function, especially when combined with whey protein powder or BCAAs (branched chain amino acids) powder. L-glutamine is considered conditionally essential because it can be synthesized by the body, but some conditions can cause glutamine levels to decrease, making supplementation necessary. Our L-Glutamine supplement is available in powder and capsule form. The powder does contain any fillers or additives. The capsules are in gelatin form and now available in 240 counts.
