99% L-Glutamine
Nanjing Gemsen
CAS 56-85-9
Our 99% L-Glutamine Powder (CAS 56-85-9) is a high-purity crystalline amino acid supplement from Nanjing Gemsen. With a molecular formula of C5H10N2O3 and molecular weight of 146.14, it meets USP37 standards, boasting a purity range of 98.5-101.5% (test result: 98.8%). This white crystalline powder is low in impurities, with heavy metals (Pb < 15 ppm, Fe < 30 ppm) and loss on drying (0.18%) well within limits. As a non-essential amino acid, it’s synthesized in the body but often supplemented to support various physiological functions.
L-Glutamine supports immune cell function and protein synthesis, strengthening the body’s defense against infections. It’s especially beneficial during periods of stress or illness when the body’s glutamine reserves are depleted.
As a precursor to mucin synthesis, it promotes ulcer healing and maintains gut lining integrity. It’s widely used to treat peptic ulcers and support overall digestive wellness.
The amino acid aids in brain function improvement, helping alleviate symptoms of mental disorders, alcoholism, and epileptic brain dysfunction. It also supports healthy mental development in children.

Conclusion: Passed test according to the Standard of USP37. | ||
Administer 5-10 grams daily (as directed by healthcare professionals) for treating peptic ulcers, alcohol poisoning, or brain function disorders.
Use in clinical settings to support patients recovering from surgery or illness.
Mix 2-5 grams of L-Glutamine powder into water, shakes, or yogurt daily. It’s a popular supplement for athletes, bodybuilders, and those seeking immune support.
Add to animal feed or bacterial culture media (dosage based on specific requirements) for biochemical research applications.
No. Unlike most amino acids, L-Glutamine is unstable in aqueous solutions. It’s recommended to prepare solutions fresh before use and store the powder in a cool, dry place to maintain potency.
Yes. Our L-Glutamine Powder is plant-derived and free from animal products, making it suitable for vegetarian, vegan, and plant-based diets.
L-Glutamine is the biologically active form used in human physiology, supporting protein synthesis and metabolic processes. D-Glutamine is the inactive isomer and not used in nutritional or medical applications. Our product is pure L-Glutamine, ensuring maximum bioavailability.
