The legal risk runs in both directions: AI engines megaphone the overclaim buried in your 2019 blog post, and they invent cure language you never wrote. For supplement and health brands, both failure modes have regulators attached.
Perplexity tells your buyers the products are made in China; your factory is in Portugal. Origin hallucinations come from category priors and stale supplier records, and they yield to explicit, evidence-backed origin data published where machines read.
Subscribe-and-save gives every product two true prices, and chatbots keep quoting the wrong one: the subscription rate as the one-time price, or a launch promo that died last spring. The fix is making both prices explicit, everywhere, as data.
You cannot force a language model to say anything, but you can make your real return policy the easiest, most corroborated fact in the room. For fashion brands, where returns decide the purchase, that is conversion infrastructure.
Some AI "hallucinations" about your products are nothing of the sort: the engine faithfully quoted the stale page your own edge cache served it. Two cache layers sit between your catalog and the answer, and you control one of them.
An AI that tells your Norwegian customer "duties included" when they are not has written a promise you never made, and the courier collects on it at the door. Cross-border duty answers get invented wherever merchants leave the facts unstated.
Supplement brands face a unique AI exposure: assistants answering health-adjacent questions can hallucinate side effects, cite your old formulation, or treat counterfeit listings as yours. Defense is a monitoring-and-source-control discipline, and it starts before the first incident.
