Biberry Extract is rich in anthocyanosides. Over 15 different anthocyanosides have been found in Bilberry. Anthocyanosides help to maintain the integrity of capillaries and to stabilize collagen. Anthocyanosides are also potent antioxidants. Numerous clinical studies have shown that Bilberry is effective in the treatment of circulation disorders, varicose veins, and other venous and arterial disorders.

The anthocyanosides protect veins and arteries by stabilizing the phospholipids of the endothelial cells and increasing the synthesis of collagen and mucopolysaccharides, which give the arterial walls their structural integrity. Anthocyanosides also prevent the aggregation and adherence of platelets to endothelial surfaces. Studies have also shown that Bilberry can act as a coadjutant in heme-ralopy and diabetic retinopathy by stimulating rhodopsin production.
