Common ingredients and the evidence

| Phosphatidylserine | Age-related memory decline | Limited | Older, small studies. |
| Ginkgo biloba | Memory, dementia prevention | Insufficient | The large GEM trial found it didn't prevent dementia. |
| Apoaequorin | Memory | Insufficient | Its maker was sued by the FTC over memory claims. |
Ratings follow our evidence scale and are updated as new research appears.
Claims to be careful with. Memory supplement claims are a long-running focus of the FTC. No supplement is proven to prevent or reverse memory loss, Alzheimer's or dementia.
