Premier Glutamine by Premier Research Labs delivers a practitioner-grade source of free-form L-glutamine, now available in a powder format for enhanced dosing flexibility and clinical application.*
Glutamine is the most abundant amino acid in the body and plays a central role in protein synthesis, muscle recovery, and gastrointestinal health.*
This formula provides L-glutamine from beneficial bacteria, offering a clean, non-synthetic source that aligns with practitioner-grade purity standards.*
Targeted Muscle & Recovery Support
During periods of physical stress or high training volume, glutamine demand increases significantly. Supplementation supports muscle recovery, glycogen replenishment, and preservation of lean muscle mass.*
By supporting protein synthesis pathways, glutamine plays a foundational role in recovery protocols, athletic performance, and overall metabolic resilience.*
Gastrointestinal Integrity & Barrier Function
Glutamine serves as a primary fuel source for intestinal epithelial cells, helping maintain the integrity of the intestinal lining and supporting mucosal health.*
Healthy glutamine levels help sustain the barrier between the gastrointestinal tract and systemic circulation, supporting the body’s natural defense against unwanted compounds and promoting optimal nutrient absorption.*
Glutathione Production & Cellular Protection
Glutamine is a critical precursor in the production of glutathione, one of the body’s most important endogenous antioxidants.*
Glutathione supports cellular protection against oxidative stress and plays a key role in maintaining liver function and detoxification pathways.*
Clean, Practitioner-Grade Powder Format*
Free-form L-glutamine derived from beneficial bacteria with no unnecessary synthetic inputs.**
