What This Product Is

L-Glutamine is a free-form amino acid available in two delivery options: vegetarian capsules providing 850 mg per capsule and an unflavored powder providing 3 grams per three-quarter teaspoon serving. Glutamine is the body’s most abundant free-form amino acid, representing approximately 40% to 60% of the total amino acid pool. Often referred to as the multitasker of amino acids, glutamine is required to perform a variety of essential functions throughout the body.*

Glutamine supports normal blood glucose metabolism, helps build lean muscle, and promotes a normal immune response. In the gut, glutamine fuels mucosal cells to support intestinal wall integrity and normal repair. Glutamine distributes nitrogen freely to the cells that need it most, including immune cells, gut cells, and muscle cells. It also serves as fuel for brain cells, helping to maintain mental energy. Additionally, glutamine increases production of glutathione, the body’s master antioxidant, supporting healthy immune response and the body’s natural detoxification of harmful substances.*

Mechanism of Action

Gut Integrity and Mucosal Cell Support

Glutamine fuels the mucosal cells of the intestine, helping strengthen the integrity of the intestinal wall and supporting a healthy gastrointestinal tract. This makes glutamine particularly valuable for maintaining the gut barrier.*

Immune System and Antioxidant Support

Glutamine provides a major source of energy for immune cells and supports immune function. It also increases production of glutathione, the body’s master antioxidant, helping protect tissues from oxidative damage and supporting the body’s natural detoxification processes.*

Muscle Recovery and Brain Health

Glutamine supports muscle recovery during exercise and sporting events and may help reduce soreness. As a precursor to neurotransmitter substances in the brain, glutamine also supports brain wellness and mental energy.*

Applications

• Individuals seeking gut integrity and gastrointestinal support*

• Those looking for immune system support through amino acid supplementation*

• Athletes wanting muscle growth and recovery support*

• Individuals seeking to support glutathione production and antioxidant status*

• Those wanting brain health and mental energy support*
