60 Delayed Release vcaps | NPN: 80079293

Glutathione (GSH) may be the most important molecule needed to boost your immune system and prevent oxidative stress (a major cause of chronic illnesses and disorders).

Supplemental glutathione, even in its widely available 'reduced' form, is very poorly absorbed in the intestine because of its molecule size. Our research has shown the best solution to efficiently boost glutathione levels is to generate it endogenously (internally) by fermentation in the gut, while simultaneously supplying easy to absorb precursors to synthesize it in the liver.

Endothione™ contains a masterful molecular blend of ingredients that start a unique gut fermentation process to produce bio-compatible glutathione, easily recognized, absorbed and utilized by the body. We have also added Selenium as a catalyst for the breakdown of hydrogen peroxide and organic hydroperoxides, and Zinc, a well known immune function booster.

The ingredients are encapsulated in a delayed release (DR) vegetarian capsule that minimizes the impact of stomach acids and maximizes ingredient absorption.

Did you know

The human body synthesizes its own Glutathione, but as we grow older, our internal Glutathione levels drop due to genetics, disease, environment, and many other factors beyond our control.

Who can benefit?

All adults are recommended daily supplementation with Endothione™.

Recommended dose

Adults take 2 capsules one time per day.
