Same UPC/GTIN observed across 2 sellers. Amazon was lowest at $17.95; Brand website was highest at $21.97 — a $4.02 range at check time.

The observed listing and exact brand page repeat 200 mg, 240 capsules. That confirms cross-page consistency of the published claim, not the product contents.

Reference prices only · no affiliate links · every compared seller must publish the matching UPC/GTIN.
