L-glutamine is an amino acid that supports a healthy intestinal lining and immune function, and assists in healing after injury or surgery and in muscle cell repair.

Thorne's L-Glutamine Powder is NSF Certified for Sport. Evidence suggests supplemental L-glutamine benefits gastrointestinal health, supports wound healing, maintains immune health, and helps restore plasma glutamine levels depleted after periods of physical stress, such as prolonged exhaustive exercise. L-glutamine is the most prevalent amino acid in the bloodstream. It is found in high concentration in the gastrointestinal tract, which is its greatest user. Various stress factors – such as trauma, infection, malnutrition, chemotherapy, injury, and high-level athletic training – can adversely affect absorption in the small intestine, leading to food allergies. In numerous animal studies, the addition of L-glutamine improved absorption, as well as the gut's immune function.

Skeletal muscles contain the greatest intracellular concentration of L-glutamine. But that concentration can be adversely affected by various insults, including injury, infection, chronic stress, malnutrition, and glucocorticoid use. Intense exercise lowers blood levels of glutamine, which can remain low if intense training is repeated without adequate recovery. Research indicates L-glutamine supplementation can offset these conditions.

Because an athlete needs to know that his or her supplements are trustworthy and compliant, every batch of an NSF Certified for Sport product is tested for compliance with label claims and to ensure the absence of more than 200 substances banned by many major athletic organizations, including stimulants, narcotics, steroids, diuretics, beta-2 agonists, and masking agents.

The NSF Certified for Sport certification program, verifies that:

• Testing products so they do not contain any of 290 substances banned by major athletic organizations
• The contents of the supplement actually match what is printed on the label
  • Toxicological review of ingredients and verification of the product
