Glutamine is the most abundant amino acid found in the body. It is synthesised in certain tissues for use in others and is the dominant amino acid in serum and cerebra spinal fluid. Theoretically glutamine improves protein synthesis by improving nitrogen balance. It has an anti-catabolic effect, which helps you to build lean muscle tissue easier. It is also considered to be good when combined with creatine for removing ammonia and forming glutathione - an important anti-oxidant.
