Actimel (known as DanActive in the United States and Canada) is a probiotic yogurt-type drink produced by the French company Danone.

[9] A 2007 study published by the British Medical Journal[10] suggests that the product could help avoid antibiotic-associated diarrhoea and limit Clostridioides difficile infections in elderly patients.

On 23 January 2008, a proposed class action was filed in California, accusing Danone Co. Inc. of false advertising in their marketing of yogurt containing probiotic bacteria (Danactive & Activia), alleging that the claimed health benefits have never been proven.

[12] Foodwatch claims that Danone "makes a mountain out of a molehill" in suggesting that Actimel protects from cold and boosts health.

[14] In the first case the ASA upheld a complaint that the advert misleadingly implied that children given Actimel would be prevented from catching bacterial infections.
