Glutamine is an amino acid that plays a crucial role in various bodily functions. It is classified as a non-essential amino acid, meaning the body can produce it, but it can also be obtained from dietary sources like meat, fish, eggs, dairy products, and certain plant-based foods. Glutamine is vital for protein synthesis, immune function, and gut health. In addition to its role in metabolism, glutamine is important for maintaining the health of cells, particularly during times of stress or illness. It serves as a fuel source for cells in the intestines and immune system, helping to support recovery and overall well-being.
