The avalanche of TV ads for Prevagen that coincided with my reaching Medicare age has inspired me to investigate what's coming for Alzheimer's disease (AD) – real treatments. Prevagen is not that.
The scenes, unending lest they immediately vanish from the viewer's disintegrating memory, show gorgeous older folks, especially couples, enjoying life and claiming that Prevagen keeps them thinking clearly, implying that they wouldn't have otherwise. A banner on the lower right proclaims "Prevagen improves memory." Yet there's no evidence that this is in fact true.
Prevagen pitches don't mention the class action lawsuit against Quincy Bioscience that was settled in 2020. Customers who had their receipt could get $70 back, and those who didn't, a generous $12. The red flag? Those claims to improve memory.
Prevagen, a "brain health supplement" and not a drug, falls into that regulatory backwater for products skirting rigorous clinical trials. The settlement demanded the company stop the claims, but "Buy Prevagen® Brain Health & Memory Improvement Supplements" appears instantly on Google. The asterisk above "Supplements" is the standard disclaimer: "These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease."
