Same UPC/GTIN observed across 2 sellers. Amazon was lowest at $9.09; iHerb was highest at $9.52 — a $0.43 range at check time.

The brand-page price is shown as a shopping lead only. It is excluded from the exact-product price difference because the page does not publish this record's matching UPC/GTIN.

The observed listing and related brand page repeat 10000 mcg. 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.
