Isotonix® OPC-3® is a powerful combination of plant derived bioflavonoids, known as oligomeric proanthocyanidins (OPC's).
It is made from a combination of grape seed, pine bark and red wine extracts in addition to bilberry and citrus extracts. These OPC's are super effective free radical neutralizers. They are not limited to being strong antioxidants, they are also crucial in their role in supporting the circulatory system and strengthening the capillaries. OPC-3® is a natural food supplement that should be taken for a lifetime.

OPCs have been used in Europe under medical supervision for over 30 years with no reports of adverse effects. Over one million people worldwide utilize these valuable bioflavonoids daily. OPCs have been tested time and time again for safety by conventional, scientific methods at leading research centers worldwide including the Pasteur Institute. OPCs have been found to be non-toxic, non-antigenic, non-teratogenic, non-mutagenic, and non-carcinogenic.

OPC-3® makes available the most potent antioxidants currently known in a rapidly bioavailable form. For best results, OPC-3® should be enjoyed with a wholesome balanced diet and dietary supplements rich in vitamin C, vitamin E, beta-carotene, and selenium, to name a few essentials for optimal health.
