Ginkgo biloba won't keep your mind sharp as you age, says a large study.

Researchers gave more than 3,000 people aged 72 to 96 either ginkgo biloba (240 milligrams) or a placebo every day. After six years, the ginkgo takers were no less likely to be diagnosed with mild cognitive impairment (which often leads to dementia). Nor were there differences on tests of memory, attention, language, or other measures of thinking ability.

What to do: Don't rely on ginkgo to maintain your memory. Instead, exercise daily, lose excess weight, and keep your blood pressure under control (see Nutrition Action, Apr. 2009, cover story).
