Anthocyanins are often combined with various monosaccharides in plants to form glycosides, called anthocyanins. The anthocyanins in blueberries have strong antioxidant properties, which can resist free radicals, delay aging, prevent degenerative changes in cells, inhibit platelet aggregation, and effectively prevent brain lesions, arteriosclerosis and other diseases. It can also strengthen capillaries, improve blood circulation, weaken the stickiness of platelets, prevent blood clots, and enhance heart and brain function.

The anthocyanins in blueberries can activate the immune system, protect immunoglobulins from free radicals, activate macrophages, and enhance the body's immunity.

　　Prevent diabetes complications

　　Since diabetic patients have very high levels of free radicals in their bodies, they will increase the risk of cancer , cardiovascular disease , stroke and other diseases, long-term supplementation of anthocyanins and other antioxidants can reduce free radicals in the body, have a significant effect on the symptoms of diabetes, and also have a preventive effect on related chronic diseases caused by diabetes. In European and American countries, natural antioxidants such as anthocyanins have been used to combat serious complications in diabetic patients for a long time.
