Glutamine is an amino acid that plays a crucial role in various biological processes in the body. It’s classified as a "conditionally essential" amino acid, meaning that while the body typically produces enough of it under normal circumstances, it may need additional glutamine during periods of stress, illness, or intense physical activity.

In terms of functions, glutamine is essential for maintaining the health and integrity of the digestive system. It is a primary fuel source for cells in the intestines and helps support gut function and the immune system. Additionally, it plays a key role in protein synthesis and muscle recovery, making it especially popular among athletes and bodybuilders. Glutamine helps repair muscle tissue after strenuous exercise, reduces muscle soreness, and supports the body’s overall recovery.

There are other benefits to glutamine as well. It helps with immune system support, particularly during times of physical or emotional stress, and it has been shown to aid in maintaining a healthy balance of nitrogen in the body, which is critical for muscle health and metabolic functions.
