Antioxidants -- the most well known of which are vitamins C and E -- are important for good health because they neutralize free radicals, which can build up in cells and cause damage. Because glutathione exists within the cells, it is in a prime position to neutralize free radicals. It also has potentially widespread health benefits because it can be found in all types of cells, including the cells of the immune system, whose job is to fight disease.
Glutathione occurs naturally in many foods, and people who eat well probably have enough in their diets, says Dean Jones, PhD, professor of biochemistry and director of nutritional health sciences at Emory University in Atlanta. Those with diets high in fresh fruits and vegetables and freshly prepared meats are most likely just fine. On the other hand, those with poor diets may get too little. The strong antioxidant effect of glutathione helps keep cells running smoothly. Bounous and another glutathione expert, Jeremy Appleton, ND, say it also helps the liver remove chemicals that are foreign to the body, such as drugs and pollutants.
Glutathione has been extensively studied for its ability to slow aging, reduce the chance of degenerative disease, improve mental performance and more. It helps the body produce and recycle antioxidants, which is vital for maintaining cellular health. When glutathione is depleted, this process is inhibited and free radicals can build up in the body. Additionally, glutathione powder binds with harmful chemicals, heavy metals and other toxins in the body and carries them into the bile and the stool so they are excreted. L-glutathione powder has been used for helping those with immune disorders, autism, digestive disorders like colitis, cardiovascular diseases and other problems.
