NOW Foods Supplements, Silymarin Milk Thistle Extract 300 mg…

Our verdict

NOW Foods Supplements, Silymarin Milk Thistle Extract 300 mg… works out to $0.16 per serving of milk thistle, at 300mg per serving in capsule form. That puts it below the median of the 32 milk thistle products we can price per dose, where the typical serving costs $0.16, a Value Index of 1.0 where the median product is 1.0. One container lasts 50 days at the label dose of 1 serving a day, about $4.79 a month. We could not verify a third-party certification for NOW 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.
