Best Bets for Memory Sharpening?

By Dr Andrew Weil

Question: What do you think of Prevagen, a product being promoted for memory repair?

Answer: I wouldn't depend on Prevagen to aid memory or "boost brainpower" as its promoters claim. I've seen no compelling, independent evidence that it helps with either. If you're concerned about memory loss, some degree of which is normal with aging, I would focus on more proven protective strategies. Keep your mind active by reading newspapers and books, doing word puzzles, playing card games or musical instruments, participating in ongoing education, and learning a new language.

In addition, accumulating scientific evidence suggests that physical exercise helps keep your mind sharp and your memory from slipping. A study at the University of Pittsburgh found that brain volume increased in areas associated with memory in seniors who took 40-minute walks three days a week for one year. And a study in mice at Columbia University found that exercise triggered blood flow and cell growth in brain areas linked to age-related memory decline.

Other evidence suggests that staying socially connected lowers risk of dementia and age-related memory loss. I believe that social and intellectual engagement is highly protective and an important strategy for healthy aging.

As for supplements to help memory, these are your best bets:
