BOOST BRAIN POWER

Pairing vitamins C and E is smart for another reason: It may lessen your Alzheimer’s risks by as much as 64 percent, according to research in the Archives ofNeurology. Just 500 milligrams of C and 400 IU of E appear to be enough. The brain’s high fat content makes it especially vulnerable to free radicals, but these antioxidants may act as shields, says study author Peter Zandi, PhD, an assistant professor at Johns Hopkins University Bloomberg School of Public Health. “Some studies suggest that vitamin E does its job reducing free radicals in the body, but then its capacity is depleted, Zandi says. “Vitamin C may recharge E:’

What to do now: Try taking C and E supplements, and talk to your doc about your risks for Alzheimer’s and dementia.

SAVE YOUR EYESIGHT

Vitamin C can’t prevent the need for reading glasses around age 45. But antioxidants, including C, help prevent one of the leading causes of blindness: age-related macular degeneration (AMD). More than 3.5 million Americans are thought to be in the early stages, and the disease strikes more women than men. A major clinical trial sponsored by the National Eye Institute showed that a daily supplement of 500 milligrams of vitamin C, 400 IU of vitamin E, 15 milligrams of beta-carotene, 80 milligrams of zinc, and 2 milligrams of copper reduced the risk of moderate or severe AMD-related vision loss by up to 25 percent. The antioxidants neutralize damage to the retina caused by, you guessed it, free radicals.

What to do now: If you’re at high risk for AMD (you’re overweight or have a family history), check to see if your multivitamin contains the study’s amounts of C, E, beta-carotene/vitamin A, zinc, and copper. Chances are, its C and E levels fall short, but additional supplements will do the job. (Caveat: Don’t follow this advice if you smoke; this level of beta-carotene may up your lung-cancer risks.)
