Product education

L-Glutamine

Supports muscle & immune health*

Glutamine is a conditionally essential amino acid that plays a key role in protein synthesis, immune support, and energy production—making it vital for active lifestyles and those under physical stress.*

Gluten free Non-GMO

Overview

What Is L-Glutamine?
While often associated with athletic performance, L-glutamine is an essential nutrient for anyone seeking to maintain muscle mass, support immune defenses, and promote gut health. It’s the most abundant free amino acid in the body, found in high concentrations in skeletal muscles and the bloodstream.*

L-Glutamine Benefits*

  • Supports healthy muscle mass and recovery*
  • Helps sustain energy levels during physical and emotional stress*
  • Promotes gut integrity and optimal immune function*

Product Details

Muscle and metabolic support
L-glutamine is used by the body during intense exercise, trauma, and stress. It fuels the synthesis of glycogen, the body’s stored form of energy in muscles and the liver. Supplementation supports quicker recovery, preserves lean mass, and enhances muscular energy reserves.*

Immune and gut health
Glutamine serves as a primary energy source for immune cells and the cells lining the gut. It supports healthy immune responses and helps maintain intestinal barrier function. This makes it especially beneficial for athletes, those under stress, or individuals with increased metabolic demand.*

Brain and antioxidant benefits
As a precursor to the neurotransmitter glutamate, L-glutamine also supports brain health. It contributes to a healthy inflammatory response and supports the body’s antioxidant defenses, which are essential for whole-body wellness under physiological stress.*

L-Glutamine is ideal for individuals aiming to support muscle health, immune resilience, and overall vitality. This non-GMO formula is easy to take once or twice daily on an empty stomach for best absorption.*
