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 1000 mg. 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.
