For nearly 2800 years the Chinese have used extracts from the Ginkgo biloba tree to treat a variety of conditions to maintain the healthy normal function of the brain, cardiovascular, blood and blood vessels, circulatory, and metabolic processes.  Ginkgo may:

• Help to maintain normal circulation  

• Help to maintain the normal function and tone of blood vessels

• Maintain oxygen and glucose metabolism in the brain

• Prevent capillary fragility and blood leakage into surrounding tissue

• Help the normal function of factors that maintain a normal blood flow

• Maintain normal coagulation of blood

• Reduce tissue damage caused by low blood flow

• May help control radiation-induced brain edema invitro

• Help slow the aging process in the brain

Ginkgo contains numerous antioxidants such as the proanthocyanidins and flavonoids, which counteract free radical activity. Flavonoids are also known to strengthen capillaries, which can promote healthy blood flow to the brain, helping to maintain cognitive health.
People often associate ginkgo with healthy cognitive function, but a review of hundreds of published studies reveals that this flavonoid probably benefits every cell in the body. In addition to maintaining healthy arterial function  via several well-defined mechanisms, ginkgo also functions as a platelet aggregation inhibitor.

Ginkgo biloba acts similar to a potent antioxidant and scavenger of most free radical species, such as hydroxyl and peroxyl radicals and superoxide anions.  It is known to protect the energy-producing mitochondria in the cells, thus enhancing oxygen utilization and cellular respiration.69* Ginkgo could inhibit production of pro-inflammatory cytokines IL-1beta and TNF-alpha, but up-regulate the production of anti-inflammatory cytokine IL-10.

Life Extension’s Ginkgo Biloba Certified Extract™ contains 24% ginkgoflavoneglycosides and 6% terpene lactones. In addition to what is certified to be in the product, what is not in this extract is also important. The health regulatory agency that regulates ginkgo purity in Germany mandates that it not contain more than 5 ppm of ginkgolic acid. Life Extension’s low-cost ginkgo contains less than 1 ppm of this toxic part of the ginkgo leaf.
