Ginkgo biloba is one of the oldest trees known, used to support health for nearly 2,800 years. Ginkgo has been found to: Support healthy circulation; Help maintain the normal function and tone of blood vessels; Support healthy oxygen and glucose metabolism in the brain; Stabilise capillaries and make them less fragile; Support normal coagulation of blood; Support healthy aging in the brain. Ginkgo leaf extracts contain nutrients with neuroprotective and cardioprotective properties. These include flavonoids, terpenoids and organic acids. Flavonoids are known to strengthen capillaries, promote healthy blood flow to the brain and help maintain cognitive health. Some of its flavonoids are potent antioxidants. Ginkgo protects mitochondria in the cells and may help to ease inflammation. In a study undergone on mice, ginkgo extract was associated with decreased genetic damage, peroxide generation and less oxidative damage. Moreover, it seemed to decrease the effects of ageing on mitochondrial function and structure. The premium-quality biochemical extract in Super Ginkgo Extract 28/7 has been concentrated and dual-standardised to ensure the highest quality, consistency and biological activity.
