Glutathione is a potent anti-oxidant and regulator of a number of biochemical processes. It is abundant in human tissues, but subject to decline with aging. Research shows that glutathione can help to reduce neurodegenerative disease, promote cartilage health, ward off age-related changes in the eye, improve immune function, and maintain more youthful skin. Overall, there is robust evidence that glutathione is a potent anti-aging compound with extensive immune and health benefits.
