L-glutamine is an amino acid found in a proportionally high amount in the body compared to other amino acids. L-glutamine is the most abundant amino acid in blood plasma and a major transporter of nitrogen. It is an important precursor for protein synthesis, and it supports cellular functions of all types. L-glutamine is also a precursor of L-glutamate (an amino acid involved in energy metabolism).

L- Glutamine assists in the process of exercise recovery and helps maintain nitrogen/ammonia balance for better muscle metabolism and also helps maintain normal function of the entire gastrointestinal tract. The amino acid glutamine plays a key role in the metabolism, structure, and function of the entire gastro-intestinal (GI) tract and its extensive immune system.
