Main highlights

Supports Muscle Recovery: L-Glutamine is the most abundant amino acid in the body and plays a crucial role in muscle recovery post-exercise. Supplementing with L-Glutamine powder can help replenish depleted levels, reducing muscle soreness and accelerating recovery time, allowing you to train harder and more frequently.

Improves Gut Health: L-Glutamine is vital for maintaining the integrity of the intestinal lining, supporting gut health by preventing leaky gut syndrome and promoting overall digestive health. Supplementing with L-Glutamine powder can aid in maintaining a balanced environment in the gut, leading to improved nutrient absorption and a healthier balance of gut flora.

Enhances Immune Function: During periods of intense physical activity or stress, the body's demand for L-Glutamine increases. Supplementing with L-Glutamine powder provides the necessary support to maintain optimal immune function, helping to fend off infections and illnesses, especially during times of physical stress.
