The Active Ingredient Is: L-glutamine (Free Form)

L-glutamine is the most plentiful unbound amino acid in human muscle, backing typical muscle metabolism and recovery processes.

This form is clean free-form L-glutamine, often made through fermentation to top purity and selected to support vegan sugar-free products.

What Does L-glutamine Do?

L-glutamine helps in muscle recovery and immune support, aiding to maintain energy availability for rapidly dividing immune and intestinal cells. It also assists with cellular hydration and pH balance during strenuous activity.

Dr. Castell at University of California found that glutamine supplementation could help contribute to faster muscle recovery after exercise and support immune function during intense physical stress.
