L-Glutamine, scientifically known as L-2-aminopentanoic acid, is an amino acid with the molecular formula C5H10N2O3 and a molecular weight of approximately 146.15. It is usually a white crystalline powder or crystal, sometimes appearing as needle-like crystals. It is odorless, has a savory and slightly sweet taste. It is stable in neutral solutions but unstable in acidic, alkaline, or hot water solutions, where it decomposes into glutamic acid or undergoes lactone formation to pyrrolic acid. In vivo, it is converted into hexosamine, becoming a precursor for the synthesis of mucins.nd hydroxytyrosol in vivo, L-tyrosine is increasingly developing towards platform-type compounds.

Maintaining the intestinal barrier and repairing the mucosa: L-glutamine is a major energy source for intestinal epithelial cells, promoting the synthesis of tight junction proteins and enhancing the intestinal mucosal barrier function. It can alleviate intestinal damage caused by inflammatory bowel disease, irritable bowel syndrome, etc., and accelerate ulcer repair.
Supporting immune cell function: As an essential nutrient for the proliferation of lymphocytes and macrophages, L-glutamine enhances antibody production and phagocytic activity, maintaining the normal functioning of the immune system. Its demand increases significantly under stress conditions such as infection, trauma, or surgery.
Regulating ammonia balance and acid-base homeostasis: As a carrier of ammonia, L-glutamine assists in transporting ammonia from peripheral tissues to the liver and kidneys for detoxification. It participates in the regulation of renal acid-base balance, helping to excrete excess hydrogen ions by generating ammonium ions.
Promoting protein synthesis and preventing muscle breakdown: By inhibiting muscle protein degradation pathways, it reduces muscle loss caused by high-intensity exercise, trauma, or disease. As a nitrogen source, it supports protein regeneration in the liver and other tissues.
Gut Health and Digestive Support: Used as a dietary supplement to improve symptoms of leaky gut syndrome, inflammatory bowel disease, and diarrhea, and to repair the intestinal mucosal barrier. Used for enteral nutritional support after chemotherapy or radiotherapy, or in critically ill patients, to prevent intestinal atrophy and infection.
Sports Nutrition and Muscle Recovery:Added to post-exercise recovery supplements to reduce muscle soreness and breakdown, and promote glycogen resynthesis. Suitable for high-intensity trainees, athletes, or those at risk of muscle loss (such as the elderly).
Immune Enhancement and Post-operative Rehabilitation:Used in individuals with weakened immunity, recurrent infections, or chronic fatigue to help enhance immune cell activity. Used as a nutritional support component after surgery, burns, and other traumas to accelerate tissue repair and infection control.
Special Medical Uses and Metabolic Support:Used to improve negative nitrogen balance and metabolic disorders in wasting diseases such as cancer cachexia and AIDS. Used as an adjunct treatment for hepatic encephalopathy to help lower blood ammonia levels.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
