NAC Supplement with Selenium

Our verdict

NAC Supplement with Selenium works out to $0.18 per serving of nac, at 1200mg per serving in capsule form. That puts it around the median of the 71 nac products we can price per dose, where the typical serving costs $0.16, a Value Index of 0.9 where the median product is 1.0. One container lasts 120 days at the label dose of 1 serving a day, about $5.33 a month. We could not verify a third-party certification for NUTRAHARMONY 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.
