Klean Glutamine 

Klean Glutamine by Klean Athlete and Douglas Laboratories provides free-form L-glutamine, an amino acid that supports muscle recovery, immune health and gastrointestinal health.

Glutamine (l-glutamine) is the most abundant amino acid in the body, serving as a source of cellular energy in muscle, gut and immune cells. Oral ingestion of this amino acid helps to replenish and restore glutamine levels, that decline during a single session of prolonged exercise. Low glutamine levels in the bloodstream are also associated with overtraining.


  • Immune health
  • Gastrointestinal health
  • Exercise recovery


Glutamine supports muscle recovery, by helping to moderate minor muscle damage associated with eccentric exercise and facilitating the storage of glycogen in muscles. Glutamine also supports muscle function and plasma antioxidant capacity in physically active elderly individuals.

Glutamine is highly utilized by immune cells, supporting white blood cell proliferation, macrophage activity and neutrophil function. Glutamine supplementation may help to moderate the effects of intense exercise on immune function. Glutamine also plays a key nutritional role in maintaining gut health, helping to maintain the integrity of the intestinal lining.
