Glutamine is the most abundant conditionally essential amino acid in the human body. Under normal circumstances, the body can synthesize sufficient amounts on its own.

It is not only the foundation for protein construction, but also a regulator and enhancer of various key physiological functions. Particularly, it plays a central role in three major areas: athletic performance, immune defense, and intestinal health.
