vitamins E & B
"THE MOST POWERFUL brain antioxidant is vitamin E," says Dharma Singh Khalsa, M.D., author of Brain Longevity. "It decreases inflammation in the brain, scavenges free radicals, [and helps] stop degeneration of cognitive function." To counteract the effects of stress on the brain, Alicia Gonzalez, N.D., a naturopath at Tashi Delek Health and Wellness in Edmonds, Wash., recommends "a good B-complex supplement that includes B6 and B12." Khalsa likes the Bs as well. "So many people complain of mental and physical fatigue, and B vitamins are very important for increasing energy," he says.
How to use it: Khalsa recommends 400 IU of vitamin E daily for the average person, and between 800 and 1,000 IU each day if you have problems with memory, concentration, and the like--along with 400 to 800 micrograms of folio acid daily. For the other B vitamins, Gonzalez suggests taking up to 1,000 mcg a day of B12 (place tablets under the tongue for best absorption) and 50 mg of B6, three times a day.
