Product Description

Product Packaging: Standard Packaging

Thorne provides L-glutamine in a convenient, cost-effective powder for ease of supplementation in large amounts.
L-glutamine is the most prevalent amino acid in the bloodstream. It is found in high concentration in skeletal muscle and lung, liver, brain, and gastrointestinal tissues. Skeletal muscle contains the greatest intracellular concentration of glutamine, comprising up to 60 percent of total body glutamine stores, and muscle is the primary storage depot and exporter of glutamine to other tissues. However, the gastrointestinal tract is the greatest user of glutamine in the body because glutamine provides the primary fuel for the nutrient-absorbing cells that line the walls of the small intestine.
Various stressors - such as trauma, infection, malnutrition, chemotherapy, and others - can impact the normal function of the enterocytes of the small intestine by adversely affecting how substances are absorbed. For example, when gut permeability is impaired it can allow large protein molecules to diffuse across the intestine - that would otherwise not - and enter the bloodstream. The body can identify these large protein molecules as foreign and mount an immune reaction against them, which can result in the development of food allergies. In numerous animal studies, in which hyperpermeability of the intestine is experimentally induced, the addition of glutamine improved permeability function as well as the gut's immune function.

I have recently completed chemotherapy and radiation treatments for Anal cancer. As you can only imagine, the "rear-end" is very burned from radiation, both inside and out. The chemo also destroys the lining of your G.I. tract. I was having trouble with bleeding issues and after taking L-Glutamine from Thorne Research twice a day, my bleeding stopped within a few days and my tissues are healing so much faster. I would highly recommend this. It is also excellent for healing the inside of the G.I. Tract too. This has been a lifesaver for me during this difficult time.

Had numerous stomach issues (was diagnosed with IBS). An alternative doctor recommended this to help heal my digestive system and another approved the supplement. It has helped, along with other supplements (e.g. probiotics) and diet changes (am off gluten and milk products).

I use this to help protect me from peripheral neuropathy. Though I still got the neuropathy, I believe it's not as bad as it would have been had I not taken this product. Mix it with juice so you can't taste it.

Flavorless nutritional supplement which is excellent for gut health. We add it to smoothies for a nutritional boost and it blends easily.
