The Ginkgo Biloba tree is the oldest tree species known to man. Today, an extract of 50:1 with a 24% potency, from the fresh green leaves of the Ginkgo tree, is one of Europe's most popular supplements. Studies have shown that 120 mg per day of 24% extract is effective. It is important to know that lower potencies of extract and/or other combinations of tablets do not yield the same results. Ginkgo Biloba Extract (G.B.E.) by Natrol is the finest suplement that science and nature can produce.
