Aricept and Prevagen haven’t been compared in clinical studies.
Prevagen is a dietary supplement. It contains a jellyfish protein called apoaequorin. This protein is thought to help protect against brain changes that may occur with aging. But its use is not regulated or approved by the FDA, and there’s no evidence that Prevagen is beneficial for dementia.
Prevagen has not been studied in adults with Alzheimer’s disease or any type of dementia diagnosis.
Aricept, on the other hand, has results from clinical studies and FDA approval to support its use in adults with dementia due to Alzheimer’s disease.
If you have questions about Aricept or Prevagen, talk with your doctor or pharmacist.
