* 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.
