À propos de cet ingrédient
Standardised extract of Ginkgo biloba leaves — globally established for cognitive support and circulatory positioning. Japanese cultivation centres on Aichi, Niigata, and Yamagata, with mature processing infrastructure for both flavone-glycoside and terpene-lactone fractions. Domestic Japanese FFC notifications cover memory and cognition support per a strict standardised-extract specification (≥24% flavone glycosides, ≥6% terpene lactones). Distinct quality controls remove ginkgolic acid below international supplement caps. Substantial export to North American and European supplement OEMs as a reference Japanese standardised extract.
