Prevagen, a supplement made by Quincy Bioscience, is one of the most heavily-advertised and expensive supplements on the drugstore shelves today. Prevagen claims in its advertising, and on its label, that the pill can improve memory. If Prevagen could really do that, it might be worth the high price, which is more than $60 for 30 pills of the extra-strength version of the product.
However, recent evidence submitted to a California court raises serious questions about whether Prevagen has any benefit to memory at all.
