Nootropic
Apoaequorin
SaveA calcium-binding protein originally isolated from the jellyfish Aequorea victoria, marketed under the brand name Prevagen as a memory supplement.
Quick verdict
The FTC challenged Prevagen's advertising claims. The single company-funded trial showed no overall cognitive benefit on the primary endpoint.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
One manufacturer-sponsored RCT (n=218) failed its primary endpoint. A post-hoc subgroup showed modest memory improvement, but post-hoc findings are hypothesis-generating at best. The protein is likely digested before reaching the brain.
Benefits
- Generally well tolerated
- Post-hoc subgroup showed modest verbal-learning improvement
Dosage notes
Marketed at 10 mg/day (Prevagen Regular).
Side effects
- Headache
- Dizziness
- Nausea (rare)
Who should be cautious
Generally considered safe but expensive relative to evidence. FTC and NY Attorney General filed deceptive-advertising complaints.
What this page cannot tell you
As a protein, apoaequorin is almost certainly degraded in the GI tract. The mechanism by which oral ingestion could affect brain calcium is unclear.
