What to send
Email the page URL, the exact product or claim, and the primary source that supports the correction. For a formula change, the region and product version are useful. Please avoid sending personal medical information or a photograph containing someone else’s private details.
How a correction is handled
We compare the report with the original and current sources, correct a confirmed error, and reassess any affected verdict or comparison. Material editorial changes receive an updated source-check note. Minor spelling and formatting corrections do not imply a new review of the underlying evidence.
This publication launched its current research set on 14 September 2026. No separate historical correction entries have been recorded for this set. This statement will change when a material correction is logged.
Product-order problems
For payment, shipment, returns or subscription cancellation, contact the retailer that accepted your order. We cannot change a merchant’s order from a link on our site. A report that a purchase link goes to the wrong item is an editorial issue and can be sent to us.
