Premier Glutamine by Premier Research Labs provides a practitioner-grade, free-form L-glutamine in powder form, offering greater flexibility for dosing and clinical use.
Glutamine is the body's most plentiful amino acid, crucial for protein production, muscle repair, and gut health.
This formula supplies L-glutamine derived from beneficial bacteria, delivering a pure, non-synthetic source that meets practitioner-grade purity standards.
Targeted Muscle & Recovery Support
During intense physical stress or high training volume, the body's need for glutamine increases significantly. Supplementing helps with muscle recovery, restores glycogen levels, and maintains lean muscle mass.
Supporting protein synthesis pathways, glutamine plays a fundamental role in recovery strategies, athletic performance, and overall metabolic resilience.
Gastrointestinal Integrity & Barrier Function
Glutamine acts as a main energy source for intestinal epithelial cells, aiding in preserving the lining's integrity and promoting mucosal health.
Maintaining healthy glutamine levels is essential for preserving the barrier between the gastrointestinal tract and systemic circulation, thereby supporting the body’s natural defenses against harmful compounds, and enhancing nutrient absorption.
Glutathione Production & Cellular Protection
Glutamine serves as an essential precursor for glutathione synthesis, one of the body’s most vital internal antioxidants.
Glutathione plays a crucial role in safeguarding cells from oxidative stress and is essential for proper liver function and detoxification processes.
Clean, Practitioner-Grade Powder Format
Free-form L-glutamine produced by beneficial bacteria without added synthetic ingredients.
