Micronized Glutamine

Glutamine is a conditionally-essential amino acid (CEAA) and an important building-block of proteins. Prolonged bouts of intense exercise can deplete your body’s nutritional reserves and overcome its ability to fully recover.

Made entirely with pure l-glutamine, R1 Glutamine is a simple way to help keep your levels elevated.

How it helps

Glutamine is an important amino acid that has several beneficial effects on the body. Here are three simple dot points on how glutamine helps:

  • Supports immune function: Glutamine is essential for the optimal functioning of the immune system.
  • Aids in muscle recovery: Glutamine is a key nutrient for muscle recovery after exercise. It helps to repair and rebuild muscle tissue that has been damaged during intense workouts.
  • Supports gut health: Glutamine is the primary fuel source for the cells that line the intestinal tract.


Mix one (1) scoop with 6-8 oz. of your favorite cold beverage or protein powder and consume before, during, or after training. 

Alternate Suggested Use 
Unflavored R1 Glutamine mixes easily into most workout supplements, protein shakes, and fruit juices.
