Ginkgo Biloba

…enhances mental performance*

Features & Benefits

  • Improves blood circulation, especially to the brain and extremities*1

  • Protects cell membranes from free-radical damage*2, 3

  • Helps normalize nerve transmission at the cellular level*

  • Reduces blood stickiness and clumping (platelet aggregation) by reducing natural production of substances that encourage clumping (platelet activity factors = PAF’s)*4

  • Contains 24% ginkgo flavones, as glycosides, heterosides, and proanthocyanidins (OPCs) and 6% terpene lactones, as ginkgolides A, B, C, and J and bilobalides

  • Ginkgo whole leaf extract, with all naturally occurring compounds, is more effective that any of the components alone5

Facts About Ginkgo

Researchers suggest that the benefits of Ginkgo biloba leaf may be related to this herb’s antioxidant in a wide range of body functions.*6

Ginkgo is particularly useful for elderly individuals suffering from poor brain function, characterized by memory impairment, difficulty concentrating and confusion.* Researchers from the University of Limburg, The Netherlands, conducted a critical review of 40 clinical trials related to Ginkgo and poor brain function.7 The researchers focused on eight trials conducted with the most stringent criteria. Of these, all but one showed positive results for the Ginkgo leaf extract compared to placebo, in terms of poor brain function.

Additional human clinical trials demonstrate favorable benefits for Ginkgo leaf extract in cases of mild to moderate memory impairment.*8 One study of 90 older adults with poor brain function found improvements in information processing, concentration and memory after the administration of 150 mg of Ginkgo Biloba extract daily for 12 weeks.9

Another function of Ginkgo biloba leaf extract reported in several studies in Ginkgo’s ability to inhibit a substance known as platelet activating factor (PAF).*10 PAF is responsible for the clumping of blood platelets, the release of histamine and increased blood “stickiness.” When blood platelets become sticky, they tend to join into clumps, which increases the risk of stroke and heart attack.

Ingredient Highlights

Ginkgo Biloba is the world’s oldest living tree species - over 200 million years old and has been used as medicine for centuries. Whole leaf Ginkgo extract is more effective that any of the components alone. The most active ingredients are terpene lactones, including ginkgolides A, B, C and J. Terpenes are more easily absorbed and have greater blood vessel protective properties than Ginkgo flavonoids.* The active flavonoids are glycosides, heterosides and proanthocyanidins (OPCs).
