NOW Foods NAC with Selenium + Silymarin Milk Thistle Supplement Bundle…

Our verdict

NOW Foods NAC with Selenium + Silymarin Milk Thistle Supplement Bundle… works out to $0.35 per serving of nac, at 600mg 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 0.5 where the median product is 1.0. One container lasts 100 days at the label dose of 1 serving a day, about $10.50 a month. We could not verify a third-party certification for NOW Foods 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.
