Blackmores Ginkgo Forte 2000 contains a standardised extract of Ginkgo Biloba, which has traditionally been used to improve blood circulation. Ginkgo Forte 2000 is ideal for older people. Ginkgo increases blood flow and so can increase tissue nutrition. It tones and helps normalise circulation as it has a relaxing (vasodilating) effect on arteries and a toning effect on veins. Ginkgo increases the fluidity of blood and in this way may improve peripheral circulation. Improving circulation can enhance the utilisation of oxygen and glucose by the body. Brain cells require large amounts of energy to function properly. Glucose and oxygen need to be constantly supplied to the brain cells to create energy, as the brain has very small energy reserves. Many studies have shown positive effects of ginkgo on working memory, the speed of information processing and learning.
