There have been links of decreasing memory loss to supplements like vitamin E, ginseng or omega 3 fatty acids, but the studies have not been large scale enough to demonstrate proven benefits concretely. Opt for more pro-active ways to improve your memory like testing your daily brain power with a new hobby, a different route home, a book outside of your favorite genre, creating an acronym for your next shopping list, attempting simple tasks with your non-dominant hand, etc. You can never go wrong with more real life brain food!
