Free radical damage affects how well we age. As the body's "master antioxidant," glutathione protects cells against free radical damage, thereby supporting the normal functioning of tissues and organs. Glutathione also plays a key role in detoxification and fortifies the immune system. Not surprisingly, over 80,000 published studies have shown that glutathione plays a central role in good health:

  • High glutathione levels appear to be associated with a long lifespan.1,2
  • Higher levels of glutathione and/or higher dietary intake of glutathione is associated with a healthier heart, eyes, colon, and more.3,4,5,6,7,8
  • Among older individuals, higher glutathione status appear to be associated with multiple measures of good health, including cholesterol, body mass index, blood pressure, blood sugar, and self-ratings of overall health.9

"A little over 50 years ago it was recognized that many chemicals we are exposed to are activated in the body to reactive chemicals. The most central way that the body gets rid of these is by reacting them with glutathione."

– Dr. Dean Jones PhD, Professor of biochemistry, Director of Nutritional Health Sciences, Emory University

Glutathione is at its lowest level in the morning and should be replenished daily through a healthy diet or supplementation such as Setria® Glutathione.
