Tanakan ® is a standardized extract of ginkgo biloba leaves. Ginkgo biloba known as one of the oldest living tree species on earth and its use in traditional medicine dates back to 3000 BC.

It is used in the treatment of cerebrovascular disorders, dementia, decreased mental capacity and tinnitus. Ginkgo extract also widely used in various OTC nootropic supplements.

The first pharmaceutical preparation of Ginkgo biloba was introduced in 1965 by German company “Dr. Willmar Schwabe Pharmaceuticals” under the trade name of Tebonin. Back then, it was one of the most widely prescribed drugs in Germany with more than 5 million prescriptions in 1988.

EGB 761 is the active ingredient of Tanakan @ and other pharmaceutical Ginkgo extracts including Tebonin. It is a standardized extract of Ginkgo biloba leaves, which consists of 24% flavone glycosides, 6% terpene lactones, bilobalide, and ginkgolides. EGB 761 is the golden standard of Ginkgo biloba supplementation and was used in hundreds of various clinical trials.

Because of the complex composition of the extract, its mechanism of action is also complex and diverse. The pharmacological effect of Tanakan relies mostly on its vasodilatory and neuroprotective properties. Ginkgo biloba is known to improve cerebral circulation, which is especially beneficial for elderly patients and patients with cerebrovascular disorders.

Neuroprotective effect of the drug is mediated by its antioxidant and free radical scavenging action, which may be responsible for its moderate anxiolytic and antidepressant effects that was demonstrated in some studies.

Here, you have a choice of several Gingko Biloba products of various manufacturers and different sizes. Bilobil is produced by a Slovenian company KRKA, Tanakan is produced by a French company IPSEN and Gingko Biloba extract is produced by a Russian company Vertex.
