CogniPlex is a high quality Ginkgo biloba leaf extract standardised to 24% of flavone glycosides (Quercetin, Kaempferol and Isorhamnetin) and 6% terpene lactones (Ginkolides A, B, C, J and Bilobalides). CogniPlex is produced by a proprietary extraction technology to ensure that the content of Ginkgolic acid is less than 5 ppm and in some special preparations it is as little as less than 1 ppm.
