NuNaturals Ginkgo Biloba Extract Capsules, 30-Count

What the brand says

NuNaturals' Pure Ginkgo Biloba Extract is made from fresh leaves which have been collected from some of the oldest living trees on the earth. These virgin Ginkgo biloba leaves are then made into an extract in a process that does not use carbon tetrachloride or acetone. This results in an extract that is free from residues. It is then tested, certified and is guaranteed to contain the European standard of 24% of the main active ingredient, the flavone glycosides (which is composed of quercetin, kaempferol, and isorhamnetin). A minimum of 6% of the terpene lactones (ginkgolides A, B, and C) are also guaranteed. Every step of production from growing to packaging is supervised to guarantee quality control. It is simply the best Ginkgo biloba extract available anywhere in the world. Our extracts are so concentrated that it takes 50 pounds of Ginkgo biloba to make just one pound of extract.
