Thorne Glutathione-SR - 60 Capsules | Thorne A sustained-release form of one of the body's most important antioxidant and detoxification factors. Thorne's Glutathione is NSF Certified for Sport®. It occurs naturally in cells and is a cofactor in dozens of enzymatic reactions involved in detoxification. As an antioxidant, glutathione directly quenches several reactive oxygen species (free radicals). The body's benefits from maintaining a normal level of glutathione include support for liver function, pulmonary function, immune function, bowel health, carbohydrate metabolism, cardiovascular health, cognitive health, and eye health. Glutathione-SR is a breakthrough in glutathione supplementation because its sustained-release formula protects it from stomach acid and digestive enzymes, allowing for a slower release and a more steady level in the bloodstream of this essential nutrient.
