Do you have trouble remembering people's names or where you left your car keys? Some studies have shown that taking ginkgo biloba supplements, made from the ginkgo biloba plant, improve mental acuity. It's not a cure for severe dementia, but if you are in the early stages of Alzheimer's disease, ginkgo may be worth a try. Studies have shown that daily doses from 120 milligrams to 240 milligrams of ginkgo biloba improved memory and brain function in people with early stage Alzheimer's disease. Most of the studies involving ginkgo have focused on Alzheimer's but evidence suggests that it may help with less severe age-related memory impairment, too.
How does it work? No one knows for sure, but evidence suggests that gingko improves blood flow to the brain, and it may stimulate certain types of nerve cells.
You don't have to be older to benefit from gingko biloba. Although the effects have not been well-studied, early evidence suggests gingko biloba may enhance memory in healthy adults of all ages. Gingko biloba can interact with blood-thinning medications, so talk to your doctor before taking gingko if you are also taking blood-thinners.
