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.
The advanced bilayer technology combines 1/3 Quick Release and 2/3 Sustained Release formats to both immediately raise and to maintain 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.
