What Does N-A-C Sustain Do?

NAC Sustain® is a Quick Release/Sustained Release formulation 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.* NAC Sustain® is formulated with advanced bilayer Sustain™ tablets that combine 1/3 Quick Release and 2/3 Sustained Release formats both to raise and to maintain blood levels with NAC release over time.

Suggested Usage

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

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. Consult a healthcare professional before using this product if you are trying to conceive, pregnant, or lactating, under the age of 18, or have a medical condition; if adverse reactions occur, discontinue use.
