In February 2019, a class-action lawsuit
was filed against Quincy Bioscience for allegedly falsely marketing that the dietary supplement Prevagen will “improve memory” and support a “sharper mind,” “clearer thinking,” and “healthy brain function” when, according to plaintiffs, the supplement does not improve memory and has no effect on the brain. (Plaintiffs amended
their complaint in May 2019.) (Engert et al v. Quincy Bioscience, LLC
, Case No. 19-cv-183, W. D. TX.)
