Our verdict

Pure Encapsulations NAC 900 mg - N-Acetyl Cysteine Amino Acid… works out to $0.47 per serving of nac, at 900mg per serving in capsule form. That puts it above the median of the 71 nac products we can price per dose, where the typical serving costs $0.16, a Value Index of 0.3 where the median product is 1.0. One container lasts 120 days at the label dose of 1 serving a day, about $14.13 a month. We could not verify a third-party certification for Pure Encapsulations in a public registry. Worked out from the current retail price as of 2026-11-13; confirm the live price on Amazon.com before buying.
