Glutamine is a crucial and abundant amino acid in the human body, serving as a building block for proteins. It’s classified as a conditionally essential amino acid because under certain circumstances, such as intense stress or illness, the body cannot produce enough and needs to get it from dietary sources. Glutamine plays a key role in many physiological processes. It aids in maintaining the health and integrity of the intestinal lining, supports immune function, contributes to protein synthesis and wound healing, and serves as a source of energy for many cells, especially those in the gut and immune system. It also plays a vital role in removing excess ammonia, a waste product of protein metabolism, from the body
