Overview
Pure Encapsulations NAC delivers 600 mg of N-Acetyl Cysteine per capsule from a freeform N-Acetyl-L-Cysteine source, in a 90-capsule gluten-free bottle positioned for lung, liver and immune support.
NAC is an amino acid derivative most often taken for its antioxidant and detox-support role, and this version uses freeform N-Acetyl-L-Cysteine rather than a blended or buffered form. Pure Encapsulations generally sits in the practitioner-grade supplement segment, and the listing's recent purchase volume, 10,000 bought in the past month, suggests steady repeat buying.

Who it's for
Suits people who want a single-ingredient NAC capsule rather than a multi-ingredient antioxidant blend, and who need a gluten-free formula. Not for anyone wanting a flavored or chewable delivery, since this is a plain capsule.
