Overview

In plain language

Prevagen is a dietary supplement designed to support memory and cognitive function, particularly in older adults. It contains the ingredient apoaequorin, which is believed to help with mild memory problems associated with aging. Many seniors consider Prevagen to potentially maintain brain health and improve mental clarity.

Prevagen is a popular dietary supplement aimed at enhancing memory and brain function, particularly for older adults experiencing age-related mild memory loss. The active ingredient in Prevagen is apoaequorin, a protein originally found in jellyfish, believed to help protect brain cells. Since its introduction in the mid-2000s, Prevagen has been marketed as a non-prescription option for those looking to support their cognitive health. While some users report improved mental clarity and memory retention, it is essential for seniors to consult with their healthcare providers before starting any new supplement, as individual results can vary and it may interact with other medications.
