Description
Product Overview
Ginkgo Biloba Extract 24/6 is a standardized botanical extract derived from the dried leaves of Ginkgo biloba L., one of the oldest living tree species with a documented history of medicinal use spanning thousands of years. Our extract is standardized to 24% flavone glycosides and 6% terpene lactones (ginkgolides A, B, C and bilobalide), with ginkgolic acid controlled to ≤5 ppm — the international benchmark for premium-grade ginkgo preparations. This natural water-soluble grade is the industry reference for cognitive health, circulation support and antioxidant nutraceuticals. Supplied by our GMP-certified manufacturing facility, it is available in customizable specification ratios to meet regional registration and formulation requirements.
