💬 — ask a question or share feedback →The FTC's investigation, joined by 39 state Attorneys General, found 8 of 10 studies Dannon cited for Activia's 'clinically proven' digestive claims showed no significant effect versus a placebo, resulting in a 2011 settlement and a separate $45 million consumer class-action payout.
Dannon marketed Activia yogurt for two years as 'clinically' and 'scientifically' proven to regulate the body's digestive system and, alongside its DanActive drink, to help boost the immune system and reduce the chance of catching a cold or flu.
The FTC's investigation, conducted jointly with 39 state Attorneys General, found that 8 of the 10 scientific studies Dannon relied on actually showed no statistically significant effect of Activia on digestive transit time compared to a placebo. Dannon settled with the FTC in 2011, agreeing to stop using the specific words 'clinically' and 'scientifically proven' in favor of softer language like 'clinical studies show,' and to stop claiming any cold- or flu-prevention benefit unless the FDA approved that specific message. Separately, a parallel consumer class action resulted in Dannon paying up to $45 million in damages, and the FTC settlement included a simultaneous $21 million settlement with the 39 states.
The word 'clinically proven' is supposed to mean something specific and verifiable, and the FTC's investigation found the actual body of evidence Dannon leaned on mostly didn't support it -- 8 of 10 studies showed no significant effect versus a placebo. A federal regulator, 39 state attorneys general, and a separate $45 million consumer settlement all landing on the same conclusion is about as thorough a real-world contradiction of a specific health claim as exists in this category.
- FTC official press release — FTC's investigation found 8 of 10 studies Dannon relied on showed no statistically significant digestive-transit effect versus placebo, resulting in a settlement requiring Dannon to drop 'clinically'/'scientifically proven' language.
