MemoPryl vs Prevagen
Prevagen is one of the most advertised memory supplements in America, built around a single jellyfish-derived protein called apoaequorin. An honest, side-by-side look at ingredients, evidence, price and value.
Quick Verdict
This is the clearest contrast of the five comparisons. Prevagen stakes everything on one protein, apoaequorin, whose memory benefits a federal court and the FTC found unsupported by reliable evidence — leading to a 2024 injunction against its core advertising claims. MemoPryl’s six-ingredient botanical blend carries no such regulatory baggage and supports both memory and stress. On the balance of ingredients, evidence and price, MemoPryl is the stronger choice; at minimum, read the FTC findings before buying Prevagen.

Frequently Asked Questions
Did Prevagen lose an FTC case?
In December 2024 a federal court affirmed an injunction, in a case brought by the FTC and New York Attorney General, ordering Quincy Bioscience to stop unsupported claims that Prevagen improves memory or is 'clinically proven.' The company has appealed aspects of the case.
What is apoaequorin?
Apoaequorin is a protein originally identified in bioluminescent jellyfish and produced synthetically for Prevagen. Critics note that, as a protein, it is broken down during digestion.

MemoPryl is a six-ingredient botanical blend (Bacopa, Rhodiola, L-Theanine, Panax Ginseng, Huperzine A, Pure Honey). Prevagen is a single-protein formula (apoaequorin plus vitamin D).
Is Prevagen more expensive than MemoPryl?
