L-Glutamine is a non-essential amino acid essential for various biochemical processes. In laboratory and biotechnology applications, it serves as a key nutrient in cell culture media, supporting the growth and proliferation of mammalian cells due to its role in nitrogen transport and energy production. It is commonly added to formulations for tissue engineering, vaccine production, and pharmaceutical research. As a specialty chemical, L-Glutamine is used as an intermediate in the synthesis of peptides, proteins, and pharmaceuticals. In the health and fitness industry, it acts as a dietary supplement to support muscle recovery, reduce soreness, and enhance immune function post-workout. Medically, it aids in gut health maintenance, intestinal repair for conditions like IBS or leaky gut, and prevents muscle wasting in critically ill patients. It also helps balance amino acid profiles in vegetarians or those with protein deficiencies.
