About this supplement
EGb 761 is a specific, standardized extract of Ginkgo biloba leaves, developed and trademarked by Dr. Willmar Schwabe Pharmaceuticals. It is one of the most extensively researched botanical extracts worldwide, with a defined chemical profile and consistent pharmacological activity. The extract is standardized to contain 22-27% flavonol glycosides and 5-7% terpene lactones (ginkgolides A, B, C, and bilobalide), with ginkgolic acids limited to less than 5 ppm to minimize allergenic potential. This precise standardization ensures batch-to-batch consistency and reproducible clinical effects, primarily targeting cerebral and peripheral circulatory function, neuroprotection, and antioxidant activity.

How it’s made
Produced via a multi-step, proprietary extraction and purification process from dried Ginkgo biloba leaves. The process involves an acetone-water extraction followed by several purification steps to enrich the desired active constituents (flavonol glycosides and terpene lactones) and rigorously remove unwanted components like ginkgolic acids, alkylphenols, and polyprenols.
