L-Glutamine is the most abundant amino acid in all musculoskeletal tissue, representing more than 60% of the amino acid pool present in striated muscle. Its function is to preserve muscle tissue in situations of stress or high-intensity exercise. Glutamine deficiency leads to increased muscle catabolism, making it essential to maintain healthy intramuscular glutamine stores. L-Glutamine supplementation protects muscle mass, promotes ammonia elimination, and improves the efficiency of aerobic energy pathways, promoting the recovery of muscle and liver glycogen. L-GLUTAMINE LINE ZERO does not contain any additives or excipients (flavorings, colorings, sweeteners, emulsifiers, anti-caking agents, preservatives, etc.), nor any added vitamins or minerals. It is, therefore, a supplement with 100% pure and natural ingredients. INSTRUCTIONS FOR USE: It is recommended to take L-GLUTAMINE during periods where its decrease is possible due to the intensity and duration of the exercise practiced. Take 3 to 9 g daily during periods of intense muscle wear, divided into three doses: before and after training and before bed. JUST-AID only sells Amino Acids in free, pure and crystalline form.
