Skip the exotic herbs and extracts -- your brain is more likely to benefit from a good old multivitamin, according to some experts. It's well known that antioxidants like vitamins C and E protect cells from damage by disarming free radicals -- naturally occurring molecules that destroy healthy cells. The brain generates more of these trouble-makers per gram of tissue than any other organ.

The advantage of a multivitamin is economy: You not only get C and E, but other key nutrients linked to healthy brain function, including beta carotene, iron, zinc, B-12 and folic acid.
