NAC with NAD+ Supplement

Our verdict

NAC with NAD+ Supplement works out to $0.06 per serving of nac, at 600mg per serving in softgel form. That puts it the cheapest quarter of the 71 nac products we can price per dose, where the typical serving costs $0.16, a Value Index of 2.9 where the median product is 1.0. One container lasts 250 days at the label dose of 1 serving a day, about $1.68 a month. We could not verify a third-party certification for DEAL SUPPLEMENT 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.
