A.Vogel's Ginkgoforce is made using freshly harvested Ginkgo biloba leaves, which are known as one of the oldest healthcare herbs. This powerful antioxidant is extracted without any toxic solvents and contains all the active principles of the Ginkgo leaf, including flavonoids, terpenes, carotenes, and more. The efficacy of Ginkgoforce is clinically proven and it is free of sugar, gluten, and lactose. The Ginkgo extract used is not standardized on one active principle, as all components are necessary for optimal efficacy.
