L-Glutamine a product no stranger to the fitness / bodybuilding community is glutamine - a conditionally essential amino acid. Glutamine is just one of 20 amino acids and becomes essential at times of metabolic stress. The body can make glutamine but under those times of metabolic stress (such as with exercise or serious training) when plasma glutamine levels may decrease, supplemental glutamine may be needed. Glutamine is a crucial component of muscle cells and the most abundant and highly concentrated free amino acid in blood and skeletal muscle. This amazing ingredient is involved in more metabolic processes than any other amino acid and can also serve as an energy precursor.*
Away from the benefits during training, this amazing amino acid also serves other purpose. The addition of glutamine to your supplement regimen may play an important role in supporting the proper function of the gastrointestinal.
Glutamine is a prominent contributor to the functional integrity of the intestines and serves as an energy source for these high activity cells. In the cells of the immune system, glutamine is pivotal in their response to “foreign” challanges, by serving both as metabolic fuel and as precursor to RNA and DNA. Glutamine is the dominant amino acid in cerebrospinal fluid and redily enters brain where it can serve as a precursor to neurotransmitters.
