S-Acetyl L-Glutathione is a highly bio-available glutathione variant for oral absorption. Glutathione is a very potent antioxidant that is naturally produced by the body (and the only one that is intracellular). It has been shown to support neuron health, liver function, and immune system health. After age 45, the body begins to produce less and less Glutathione and many individuals begin to support their glutathione levels through supplementation.
Unfortunately, most Glutathione supplements have nearly no bioavailability, as the molecule breaks down rapidly after oral ingestion. S-Acetyl L-Glutathione is an altered form with an attached acetyl function group. This greatly improves its ability to remain intact in the gut and allows a greater concentration to be absorbed into the bloodstream where it can take effect.
