Ginkgo
Ginkgo biloba is an herbal extract derived from the oldest-known species of tree. Ginkgo biloba offers a number of benefits, including enhanced circulation, increased blood flow to the brain and extremities, and enhanced delivery of oxygen and glucose to nerve cells. Ginkgo biloba is considered a "brain booster" that supports mental alertness, clarity and concentration. Ginkgo is also an antioxidant that protects healthy cells from the damaging effects of free radicals. Look for ginkgo biloba supplements in tablet, capsule, liquid or powder form. Ginkgo can be taken safely on a long-term basis, with a general-recommended dose of 120 mg (divided) daily.
