L-glutamine is an amino acid that is classified as a conditionally essential amino acid, meaning that while the body usually produces enough of it, there may be times — like during illness, injury, or intense physical activity — when supplementation can be beneficial. It plays a crucial role in various physiological functions, including protein synthesis, immune system support, and maintaining gut health. Glutamine is particularly important for athletes and those engaging in heavy workouts, as it can help in muscle recovery and reduce muscle soreness after exercise.
In terms of dietary sources, L-glutamine is naturally found in high-protein foods such as beef, chicken, fish, eggs, dairy products, and certain plant-based foods like beans, lentils, and spinach. Many people choose to take L-glutamine supplements to bolster their intake, particularly when they are involved in rigorous training or are recovering from surgery or trauma. However, as with any supplement, it’s advisable to consult healthcare professionals before starting to ensure it aligns with your health needs and dietary goals.
