Why isn’t glutathione found in the CellSentials?

Glutathione is a compound involved in one of the body’s most important antioxidant systems. However, glutathione itself is not absorbed intact very efficiently. One of the best ways to increase glutathione levels is to provide the building blocks and precursors needed to manufacture it within the body.

N-acetyl L-cysteine (NAC) is an effective precursor to glutathione, and it is more efficiently absorbed than glutathione itself. Because of this, USANA includes high levels of NAC in the CellSentials as opposed to actual glutathione. We also provide substantial amounts of other important nutrients associated with glutathione production, including selenium and vitamin E.
