L-Glutamine (CAS 56-85-9) is one of the most abundant free amino acids in the human body, naturally present in muscle tissue, blood, and other organs. As a conditionally essential amino acid, it plays an important role in protein metabolism, muscle maintenance, digestive balance, and overall wellness. It also serves as a key fuel source for certain cells and supports various physiological processes.
Natural Field offers high-purity bulk L-Glutamine Powder produced in strict quality control and third-party verification. Our ingredient provides excellent solubility, stable quality, and consistent particle size, making it suitable for capsules, tablets, powder blends, RTD beverages, sports nutrition, and functional wellness formulas.

To further enhance the efficacy of your formulations and cater to diverse wellness needs, we recommend pairing our L-Glutamine Bulk Powder with our premium complementary raw materials—all of which are core products of Natural Field and feature proven synergistic effects.
For sports performance enhancement, our bulk BCAA powder (Branched-Chain Amino Acids) and Beta-Alanine powder are optimal choices: BCAA collaborates with L-Glutamine to promote muscle protein synthesis and reduce post-exercise muscle breakdown, and both are listed side by side in our sports nutrition product line; Beta-Alanine increases carnosine levels to enhance muscle endurance, while L-Glutamine supports gut health and immunity, jointly improving athletic performance and recovery.
For immune reinforcement, our Vitamin C powder and Glutathione powder complement L-Glutamine perfectly: Vitamin C enhances antioxidant capacity to synergistically boost immune defense, with both products featuring compatible stability and available in high purity at Natural Field; as a sulfur-containing amino acid, L-Glutamine serves as a precursor for glutathione synthesis, and the two work together to strengthen antioxidant and immune functions, ideal for people exposed to environmental pollution and high pressure.

Some key functions of L-Glutamine include:
Muscle Growth and Repair: L-Glutamine helps provide the nitrogen source needed for muscle growth, promotes protein synthesis within muscle cells, and increases strength and endurance.
Immune System Support: As a primary energy source for immune system cells, L-Glutamine is essential for maintaining the health and function of immune cells.
Intestinal Health: L-Glutamine is a major energy source for intestinal cells and helps maintain the integrity and function of the intestinal mucosa, which is crucial for preventing leaky gut syndrome and promoting nutrient absorption.
Brain Function: L-Glutamine can cross the blood-brain barrier and has a positive impact on brain metabolism, which may help improve memory and learning capabilities.
Exercise Performance: After endurance exercise, supplementing with L-Glutamine may help reduce muscle soreness, speed up recovery time, and support immune function post-exercise.
Stress and Illness Recovery: When the body is under high stress or during illness, the demand for L-Glutamine may exceed the body's production capacity. In such cases, supplementing with L-Glutamine may aid in the recovery process.
