Ginkgo biloba is a natural extract derived from the leaf of the Chinese ginkgo tree, also called the maidenhair tree, noted for its cerebral-enhancing effects. Ginkgo biloba extract contains two constituents (flavonoids and terpenoids) that have strong antioxidant properties. It’s believed these may help slow down the progression of age-related diseases by combating oxidative stress that usually worsens as someone ages. For people of all ages, its ability to increase vascular dilation and improve health of blood vessels means it supports brain activity, development, detoxifying mechanisms and immune function. Many of ginkgo’s most prominent benefits are tied to brain function like focus and memory as well as mental performance.
