THE SCIENCE BEHIND SETRIA® GLUTATHIONE

Setria® Glutathione is a manufactured and purified form of Glutathione, a natural compound made from the amino acids glycine, cysteine, and glutamic acid. It is found in nearly every cell of the human body and is critical for protecting cells against oxidative stress and for tissue building and repair.

Chart showing the effect of Setria Glutathione supplement over 6 months

1: Setria® can help increase the body’s stores of glutathione*

Taking 1,000mg/day of Setria® showed a 30% increase in whole blood, 35% increase in red blood cells and 260% increase in buccal cells glutathione levels.

NK Cell activity when taking Setria Glutathione supplements for 3 months

2: Setria® can increase NK cell activity two fold and support the immune system

At three months the study revealed a 2 fold increase in NK cell activity at 1,000mg of Setria®. (NK cells support immune health).

Glutathione levels after stopping supplementation of Setria

3: Setria® supplementation needs to be ongoing to maintain levels

1 month after supplementation ended glutathione levels began to return to pre-study levels. Setria® glutathione does not adversely affect the body's normal production of glutathione.

Glutathione is sometimes referred to as the ”master antioxidant” supporting a healthy immune system, improving skin health and the signs of aging, and contributing to the body’s antioxidant levels.
