The Active Ingredient Is: Glutathione (L-Glutathione)

Glutathione is a master antioxidant found in cells throughout the body, supporting cellular protection against oxidative stress.

This form is Setria L-glutathione, a stable, reduced form used in capsules to supply the active nutrient. The product also contains excipients such as rice flour and gelatin in its formulation.

What Does Glutathione Do?

Glutathione assists with neutralising free radicals and supports detoxification processes, contributing to cellular defence and the recycling of other antioxidants.

Dr. Forman of the University of Edinburgh found that glutathione functions as a cellular guardian, helping to maintain redox balance and support antioxidant networks.
