Gaia Herbs Milk Thistle

Our verdict

Gaia Herbs Milk Thistle works out to $1.28 per serving of milk thistle, at 375mg per serving in capsule form. That puts it above the median of the 32 milk thistle products we can price per dose, where the typical serving costs $0.16, a Value Index of 0.1 where the median product is 1.0. One container lasts 40 days at the label dose of 1 serving a day, about $38.47 a month. We could not verify a third-party certification for Gaia Herbs 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.
