Ginkgo no-go.

Ginkgo won't prevent your brain from sliding into dementia.

Investigators randomly assigned 482 people with mild cognitive impairment and 2,587 people with no memory problems to take either ginkgo (120 milligrams) or a placebo twice a day. The ginkgo extracts used in the study, which are made by Schwabe Pharmaceuticals, are used in many brands of ginkgo sold in the United States.

After six years, the ginkgo takers were no less likely to be diagnosed with Alzheimer's or other dementias than the placebo takers.

What to do: Don't depend on supplements to keep your mind sharp. Instead, eat a healthy diet and step up your exercise. That may protect your brain by lowering your risk of obesity, diabetes, high blood pressure, and heart disease. Keeping your mind active may also help.
