NAC Sustain™ is in a bilayer Quick Release/Sustained Release format of N-ACETYL-L-CYSTEINE (NAC), a powerful antioxidant amino acid and a precursor to the critical antioxidant glutathione. Glutathione exerts a variety of protective effects, including detoxification and intracellular defense against oxidative stress. Substances known to reduce gluthathione status are acetaminophen and alcohol.*

The advanced bilayer technology combines 1/3 Quick Release and 2/3 Sustained Release formats to both immediately raise and to sustain blood levels over a longer period of time. NAC Sustain™ releases in the small intestine over a 4 hour period, compared to the 1.5 hour biological half-life of NAC in the bloodstream.
