Jarrow Formulas N-A-C Sustain®
NAC SUSTAIN® is a special Sustain™ 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 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 maintain blood levels over a longer period of time. NAC Sustain™ releases in the small intestine over an 8 hour period, compared to the 1.5 hour biological half-life of NAC in the bloodstream.
