Key Ingredients

Grape Seed Extract: 25 mg
Grape seed extract is typically extracted from the seeds of red grapes (instead of white), which have a high content of compounds known as oligomeric proanthocyanidins (OPCs). Grape seed extract is extremely rich in polyphenols, compounds with high antioxidant activity. Grape seed extract has been found to maintain healthy cholesterol levels.*

Red Wine Extract: 25 mg
Red wine extract is a powerful antioxidant. This extract is found in grape vines, roots, seeds and stalks, with the highest concentration in the skins. The antioxidant properties of red wine extract contribute to maintaining healthy circulation by strengthening capillaries, arteries and veins, and promoting overall cardiovascular health.*

In the late 1990s, scientists took note of a phenomenon among the French. There were very low rates of cardiovascular problems in the provinces where residents consistently ate high fat foods and drank red wine. Scientists concluded that the protective properties of red wine have helped the French maintain cardiovascular health for years and subsequent scientific studies have further shown that the OPCs found in red wine are particularly beneficial for protecting the heart and blood vessels.*

Pine Bark Extract (Pycnogenol®): 25 mg
Pycnogenol® is a natural plant extract from the bark of the maritime pine tree, which grows exclusively along the coast of southwest France in Les Landes de Gascogne. This unspoiled and natural forest environment is the unique source of pine bark. Pycnogenol is one of the most researched ingredients in the natural product marketplace. Published findings have demonstrated Pycnogenol's wide array of beneficial effects on the body. Pine bark extract is an all natural combination of procyanidins, bioflavonoids and organic acids.*

The extract has three basic properties — it is a powerful antioxidant, selectively binds to collagen and elastin, and promotes the normal production of endothelial nitric oxide, which promotes the normal dilation of dilate blood vessels.*

As one of the most potent natural scavenger of free radicals, Pycnogenol combats many aggressive free radicals before they cause oxidative stress to vital organs. Its super-antioxidant capabilities help support healthy blood platelet activity, support healthy blood glucose levels, reduce mild menstrual cramping and abdominal pain, maintain joint flexibility, promote cardiovascular health, promote healthy sperm quality, maintain healthy cholesterol levels and support a healthy complexion.*

Bilberry Extract: 25 mg
Bilberry extract is derived from the leaves and berry-like fruit of a common European shrub closely related to the blueberry. Extracts of the ripe berry are known to contain flavonoid pigments known as anthocyanins, which are powerful antioxidants. Scientific studies confirm that bilberry extract supports healthy vision and venous circulation. Bilberry extract helps maintain healthy circulation by strengthening capillaries, arteries and veins.*

Citrus Extract (Bioflavonoids): 25 mg
Bioflavonoids are antioxidants found in certain plants that act as light filters, which protect delicate DNA chains and other important macromolecules by absorbing ultraviolet radiation. They have been found to promote cardiovascular health, help maintain healthy circulation by strengthening capillaries, arteries and veins, and demonstrate anti-inflammatory activity.*

What Makes Isotonix® OPC-3® Unique?
Isotonix® OPC-3® is an isotonic-capable food supplement that is made from a combination of bilberry, grape seed, red wine and pine bark extracts, and citrus extract bioflavonoids, all found to be powerful antioxidants. Oligomeric proanthocyanidins (OPCs) are bioflavonoids (complex organic plant compounds) found in fruits, vegetables and certain tree barks that provide exceptional nutritional benefits to the human body. Studies have shown OPCs to be up to 20 times more powerful than vitamin C and 50 times more powerful than vitamin E in neutralizing free radicals. Isotonix® OPC-3 contains the only isotonic form of Pycnogenol® in the world. Pycnogenol is a natural plant extract from the bark of the French maritime pine tree and the most clinically researched and potent bioflavonoid.*

Isotonic, which means "same pressure," bears the same chemical resemblance of the body's blood, plasma and tears. All fluids in the body have a certain concentration, referred to as osmotic pressure. The body's common osmotic pressure, which is isotonic, allows a consistent maintenance of body tissues. In order for a substance to be absorbed and used in the body's metabolism, it must be transported in an isotonic state. Isotonix® dietary supplements are delivered in an isotonic solution. This means that the body has less work to do to in obtaining maximum absorption. The isotonic state of the suspension allows nutrients to pass directly into the small intestine and be rapidly absorbed into the bloodstream. With Isotonix® products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.*
