L-Glutamine

Thorne L-Glutamine delivers the most prevalent amino acid in the bloodstream, concentrated where the body needs it most — the gastrointestinal tract. Formulated for athletes, those recovering from physical stress, and anyone seeking to support gut barrier function and immune health as part of a consistent wellness routine.

L-glutamine, the most prevalent amino acid in the bloodstream, is found in high concentration in the gastrointestinal tract, which is the greatest user of glutamine. Many factors can play a part in the depletion of glutamine, such as food allergies, and various bodily insults like injury, infection, chronic stress, and being malnourished. Intense exercise can also adversely lower the blood level of glutamine and, if intense training is repeated without adequate recovery, then the level can remain low.

What causes glutamine depletion: 

• Prolonged exhaustive exercise
• Extended periods of physical stress
• Trauma or infection
• Being malnourished
• Chemotherapy
