What is L-Glutamine?
L-Glutamine Powder is the most abundant Amino Acid (building block of protein) in the body.It participates in the biosynthesis of glucosamine, a component of mucin of the digestive tract mucosa, which promotes the repair of mucosal epithelial tissue and contributes to the elimination of ulcer lesions.The body can make enough glutamine for its regular needs, but extreme stress (the kind you would experience after very heavy exercise or an injury), your body may need more glutamine than it can make. Most glutamine is stored in muscles followed by the lungs, where much of the glutamine is made.

L-Glutamine Benefits
1. Faster Recovery - L-Glutamine helps repair muscle mass. When the body is under severe physical stress, more Glutamine is consumed as an automated response to speed the healing process than is available from muscle stores. Therefore supplementing with an L-Glutamine powder is vital for recovery in order to restore your body's optimal levels of Glutamine.
2. Increased Strength - High-intensity training programs require the body to utilize amino acids that help build muscle tissue. A positive balance in essential amino acids will help promote protein synthesis, for anabolic muscle growth.
3. Boosts Athletic Performance - Faster recovery times between training sessions will help increase training volume and endurance.
4. Gut & Digestive Health - L-Glutamine assists in rebuilding and repairing the intestinal tract and lining of your gut.
