Blueberry are basically the European version of the American blueberry. Bilberries are grown in Europe, Canada and the U.S. and extracts of the ripe berry are known to contain flavonoid pigments known as anthocyanins - which act as powerful antioxidants.
Modern laboratory studies on bilberry extract have confirmed a number of activities including antioxidant effects, an ability to inhibit aggregation of blood platelets (reduce stickiness, hence a tendency to clotting of blood cells), produce a slight relaxation effect on vascular smooth muscles, and a possible role in reducing factors associated with chronic inflammatory diseases.Rongsheng biotech is a leading Cranberry Extract producer in China.
Extracts of the bilberry fruit have also been shown in laboratory experiments to inhibit enzymes such as elastase, which can cause the degradation of collagen. This can lead to a reduction in factors associated with inflammatory conditions such as atherosclerosis, pulmonary emphysema, and rheumatoid arthritis.
The effectiveness of the bilberry extract was linked to a group of compounds called "anthocyanosides." These compounds are derivatives of anthocyans - the pigments
responsible for the red, blue or violet colors in flowers and fruits. The majority of studies on
bilberry have involved extracts purified to contain from 25 to 36 percent anthocyanosides.
At least fifteen different anthocyanoside compounds have been identified in bilberry extract.
Most standardized bilberry extract available as dietary supplements on the American market contain 25 percent anthocyanosides.
Store in cool and dry places. Keep away from strong light.
You can get all the anthocyanins you need by eating ½ to 1 cup of fresh bilberry or blueberry with your breakfast. Standardized extracts are often more convenient, where doses should approximate 100 – 500 mg per day (25% anthocyanosides) in 2 to 3 divided doses.
Under recommended intakes, bilberry extract is safe. In some cases, it may even be recommended for use during pregnancy for prevention and treatment of varicose veins and hemorrhoids. ALL women, however, who are pregnant or breastfeeding should check with her personal physician before taking this, or any, dietary supplement.
