NAC supports your body's master antioxidant system for superior cellular protection. This amino acid derivative works as a precursor to glutathione, scientifically proven to neutralize free radicals and support cellular longevity. Natural Factors delivers pharmaceutical-grade NAC that your body actually uses.
Why It Works
GLUTATHIONE PRECURSOR: Unlike direct glutathione supplements that break down in digestion, NAC crosses cell membranes and converts to glutathione where your body needs it most.
FREE RADICAL SCAVENGER: Supports your cellular defense systems against oxidative damage from exercise, pollution, and daily stress.
RESPIRATORY HEALTH: Maintains healthy lung tissue and supports your body's natural respiratory defenses, especially beneficial for active people.
What's Inside
Pure N-Acetyl-L-Cysteine in vegetarian capsules. No artificial colors, preservatives, or unnecessary additives. NPN N/A. Made in Canada under strict quality standards.
Why we carry it: Natural Factors consistently delivers pharmaceutical-grade NAC with proven bioavailability — the real difference in antioxidant protection.
1 capsule 2 times daily or as directed by a health practitioner.

The BEST. Period.
I typically make my own tinctures, but not Chastetree. SO glad I was able to find it on Vitasave. And I take the NACL regularly in these smokey Canadian summers, and to not have to drive 1 1/2 hrs to get it, BONUS! Great quality. Super fast delivery. Best Free Shipping deal ($99+ in Canada).
