Extra Strength Ginkgo is derived from the Ginkgo biloba tree leaf. Thriving on Earth for more than 200 million years, the Ginkgo tree is the world's oldest living plant. Considered sacred in the Orient, Ginkgo was the only surviving tree near the epicenter of the Hiroshima atomic bomb blast. One specimen, planted near a Japanese monastery more than 1,000 years ago, is still alive today.* Ginkgo biloba extracts rank high among the most popular herbal products in Europe, where sales exceed $500 million annually. Ginkgo biloba extract is non-toxic, free of side effects, and safe for continuous use at the recommended intake level. Best Ginkgo Extract should be taken for four weeks or more before results can be expected.* Rich and Concentrated The Ginkgo biloba leaf is rich in phytonutrients, chiefly flavonglycosides and terpene lactones (ginkgolides). In the extract, these bioflavonoid-like active ingredients are highly concentrated. Fifty pounds of Ginkgo leaves are used to yield one pound of extract.* Supports Brain and Cognitive Function* Numerous clinical studies have been published on Ginkgo biloba extract. Much of this extensive research deals with Ginkgo’s beneficial effects on the brain and mental function. Foremost among its actions, Ginkgo biloba extract supports circulatory function in the brain. Enhanced blood flow to the brain means better delivery of oxygen and nutrients. The clinically observed benefits of Ginkgo biloba extract include improved short-term memory and a positive effect on mood, sociability, thinking ability and hearing.* Powerful Antioxidant Ginkgo biloba extract is a powerful antioxidant. Acting as free-radical scavengers, Ginkgo’s flavonglysosides help prevent damaging peroxidation of cell membrane lipid components.* Improves Circulation Ginkgo supports circulation in the extremities as well as the brain. By maintaining blood flow in the extremities, Ginkgo biloba extract supports oxygen delivery to tissues and promotes the ability to walk without discomfort. In addition, ginkgolides have been shown to inhibit Platelet Activating Factor (PAF). Controlling PAF reduces clumping of blood platelets and improves circulatory health.*
