* Proanthocyanidins, lack of oxygen in the elderly, may cause mental and physical problems, such as Alzheimer's disease. Older people often have poor blood circulation. Proanthocyanidins scavenge free radicals and inhibit the rupture of capillaries and the destruction of surrounding tissues. Proanthocyanidins also improve the state of capillaries and enhance blood circulation to the brain, so the brain can get more oxygen.
* Proanthocyanidins can also improve women's premenstrual tension syndrome and other problems.
