Ginkgo biloba has been studied for many years, with research demonstrating its powerful antioxidant potential as well as its ability to support circulation, thereby improving glucose and oxygen transport, particularly to the brain. Our Ginkgo biloba is European standardized ginkgo from a world leader in the manufacturing of European extracts used in clinical studies. European herbs are manufactured to the same standards as over-the-counter drugs in the USA. More importantly, the herb must demonstrate efficacy and safety before it can be sold to the public. The two active ingredients that provide the most significant health benefits are the flavone glycosides and terpene lactones, both of which our ginkgo is consistently standardized for.
