The extract of the grape seeds-proanthocyanidin can effectively lower the arteriosclerotic degree, and therefore keep the blood vessels active, elastic and healthy.
Proanthocyanidin is the known most effective antioxidation substance. It can boost the strain of blood vessels and restore blood vessel's function back to normal. Natural OPC and natural Polyphenol have polyphenol antioxidation function which is 50 times as strong as Vit.E 50. Consuming antioxidation material on a daily basis can exhibit heart and blood vessel disease, arteriosclerosis, skin aging, and disbetes syndrome, maintain body's circulation system, reduce blood fat, control cancer, eliminate bad breath and stomatitis, and prevent cataract and early Parkinson's disease.
