ForjamuscularMicronization and solubility parameters
Pure L-glutamine synthesized through plant-based fermentation requires mechanical particle reduction to overcome its natural hydrophobicity. 200-mesh micronization reduces average particle diameter below 75 microns, facilitating cold water dispersion and accelerating release to enterocytes.
Third-party laboratory testing
Free-form amino acid purity is confirmed through standardized testing protocols that rule out synthesis impurities or bacterial by-products:
- High-performance liquid chromatography: Verifies an active fraction exceeding 99.3% with no dextrorotatory isomers.
- Heavy metal screening: Lead, mercury, and cadmium levels below 0.1 parts per million.
- Source traceability: Fermented from non-GMO plant glucose.
Functional relevance for endurance athletes
During sustained exercise lasting over ninety minutes, plasma glutamine concentrations drop significantly due to rapid uptake by immune cells and the intestinal mucosa. Using unflavored micronized powder replenishes metabolic reserves without impairing gastric emptying during demanding training blocks.
