Ginkgo Extra clinical studies

Spectacular results of one of these microcirculation studies with Ginkgo Extra , plus the result of a product safety and tolerance study done by physicians.


Only a few research groups worldwide have the equipment and experience to carry out modern microcirculation research. The "Institute for Microcirculation" in Berlin is the leading research centre on microcirculation in Europe. We have conducted  studies with Dr. Rainer Klopp, Director of the Institute and recognized expert of microcirculation.
