NAC Sustain is in Jarrow's SUSTAIN™ bilayer Quick Release/Sustained Release format of 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 glutathione status are acetaminophen and alcohol.
The advanced bilayer Sustain™ tablets combine 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(R) releases in the small intestine over a 8 hour period, compared to the 1.5 hour biological half-life of NAC in the bloodstream.
