NAC SUSTAIN is in our 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 oxidativestress. 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 releases in the small intestine over a 4 hour period, compared to the 1.5 hour biological half-life of NAC in the bloodstream.


Suggested Usage:


Take 1 SUSTAIN tablet 1 to 2 times per day, preferably on an empty stomach with fruit juice or as directed by your qualified health care consultant. 

NOTE: Prolonged or elevated intake may alter liver function tests without affecting actual liver function. Inform your physician that you are ingesting NAC if you undergo liver function tests.
