Ginkgo Leaf Extract tablets are believed to help maintain memory with age and to support healthy cognitive function. Ginkgo leaves from this extract are taken from the Ginkgo Biloba Tree, one of the oldest trees in the world. These trees have been used for their benefits for many years, and their properties are thought to have been established in ancient Chinese medicine. Ginkgo supplements are one of the most popular supplements used by the over 50s today, thanks to them gaining more popularity in Western cultures. The active ingredients in ginkgo are flavones called glycosides. These tablets have been specially coated, making them easier to swallow.
