The Active Ingredient Is: L-Glutamine (Free-Form Amino Acid)

L-Glutamine is a non-essential amino acid that serves as a major energy source for muscle and immune cells and supports protein synthesis. This product provides pure L-glutamine in its free-form form, the most abundant free amino acid in muscle tissue.

This form is supplied as a simple, hypoallergenic amino acid and is intended to support overall physiological function related to muscle repair and gut health.

What Does L-Glutamine Do?

L-Glutamine assists with fuel for muscle and immune cells and supports gut barrier integrity, helping to maintain healthy digestive function. It also acts as a precursor to neurotransmitters, which can contribute to cognitive function.

Dr. Legault of the University found that L-glutamine supplementation may reduce muscle soreness and speed recovery after strenuous exercise.
