Supersmart - Butterbur Extract 100mg Per Day - Extract of Petasites…

Our verdict

Supersmart - Butterbur Extract 100mg Per Day - Extract of Petasites… works out to $0.35 per serving of butterbur, at 100mg per serving in capsule form. That puts it below the median of the 21 butterbur products we can price per dose, where the typical serving costs $0.35, a Value Index of 1.0 where the median product is 1.0. One container lasts 60 days at the label dose of 1 serving a day, about $10.50 a month. We could not verify a third-party certification for Supersmart 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.
