A nationwide class action settlement was just reached involving approximately 3 million consumers of a popular supplement claiming to improve brain health. The settlement, which is subject to court approval, will provide those consumers with partial refunds, and the supplement will have a changed label.

Consumers of the supplement, Prevagen, said that Quincy Bioscience, the supplement maker, was deceptive in its advertisements claiming that the brain health supplement improved memory and “supported brain function, [a] sharper mind, and clearer thinking.”
