Cysteine contains sulfur, which is critical for making glutathione. NAC delivers the active form of cysteine from the digestive tract into cells, where cysteine is then converted into glutathione. Cysteine is the component most likely to be in short supply when the body produces glutathione. If NAC has been altered, it may no longer be in the active cysteine-related form needed for intracellular conversion.
