Jarrow Formulas N-A-C Sustain is a patented, extended release form of N-Acetyl-L-Cysteine (NAC), an antioxidant amino acid and a precursor to the critical antioxidant glutathione.

Substances known to reduce glutathione status are acetaminophen and alcohol.
NAC has a biological half-life of 1.5 hours in the bloodstream. Jarrow Formulas N-A-C Sustain will release in the small intestine over a 4 hour period in order to maintain blood levels over a longer period of time.
Take 1 to 2 sustain tablets per day, preferably on an empty stomach with fruit juice, or as directed by your qualified health consultant.
