How nutraMetrix® Pet Health OPC Formula with Glucosamine Benefits Your Pet*
nutraMetrix® Pet Health OPC Formula for Cats & Dogs with Glucosamine is a unique, great-tasting powder that is sprinkled over your pet’s regular food. It represents the latest technology available today in naturally based pet food supplements. nutraMetrix® Pet Health OPC Formula is available in a tasty beef flavor that your pets will love – and you’ll love knowing that you’re doing all you can to help your pets live long, healthy lives.
nutraMetrix® Pet Health OPC Formula is a food supplement made from a combination of bilberry, grape seed, red wine, pine bark extracts, citrus extract bioflavonoids, and glucosamine, designed to promote healthy joints and provide a strong antioxidant defense. Oligomeric proanthocyanidins (OPCs) are bioflavonoids that provide exceptional nutritional benefits to your pet’s body. Studies have shown OPCs to be more powerful than vitamin C and vitamin E in neutralizing free radicals. Powerful antioxidants like OPCs help to strengthen your pet’s free radical defenses. Antioxidants promote cardiovascular health, support healthy visual acuity, promote healthy blood vessel dilation and promote healthy platelet activity.
As pets become older, antioxidants become even more important in the fight against free radicals and their associated effects on cells in joints and other tissues. All animals need joint support as they age. Many factors can affect joint health and the integrity of cartilage, including diet, genetic make-up and activity levels. The cold winter months can also contribute to a decline in joint comfort. Proper nutrition, especially antioxidant supplementation, is critical in maintaining healthy joints. Glucosamine has been shown to promote the retention and normal regeneration of cartilage, support normal movement and flexibility of joints and promote joint comfort.

Antioxidant power and joint health in one
Key Ingredients
Grape Seed Extract
Grape seed extract helps protect cells from free radicals. Rich in polyphenols, beneficial compounds that have been shown to support normal circulation, grape seed extract can help maintain a healthy circulatory system.
Red Wine Extract
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.
Pine Bark Extract
Another strong antioxidant, pine bark extract has been shown to support normal circulation, and the strength of blood vessel walls.
Bilberry Extract
Bilberry extract is beneficial in promoting strong red blood cells and capillaries, specifically around the eyes and in the retina. Bilberry extract supports the capillaries in the body to help maintain optimal peripheral circulation.
Citrus Bioflavonoids
Citrus bioflavonoids are natural substances found in fruits and vegetables, nuts, and some tree barks. They counter the effects of free radicals and also support normal respiratory health.
Glucosamine
Glucosamine is a molecule that is naturally synthesized in the body from glucose and the amino acid glutamine.There are numerous European studies showing a clear benefit of glucosamine supplements for promoting joint health. Glucosamine may also support chondrocytes (cartilage cells) in the normal production of healthy new cartilage.
Glucosamine is an important constituent of glycosaminoglycans in cartilage matrix and synovial fluid. As bodies age, they are less able to produce glucosamine, resulting in cartilage that is less flexible and weak. Although the mechanism is currently unclear, studies have shown that glucosamine supplementation can support normal, healthy cartilage cell production to help maintain overall joint health. It has been suggested that several antioxidants blended together in moderate amounts may be more effective than high levels of one antioxidant.
The blend of antioxidants in Pet Health OPC Formula includes grape seed extract, red wine extract, pine bark extract, bilberry extract and citrus bioflavonoids. These antioxidants contain oligomeric proanthocyanidins, or OPCs. Much the same way antioxidants can help optimize a person's health, they can also be beneficial to our dogs and cats. Antioxidants help fight free radicals. Young animals can benefit tremendously from antioxidants. Antioxidants can help maintain optimum health in your animal's cardiovascular systems, joints and eyes.
FAQs
1. What are OPCs?
OPCs, or oligomeric proanthocyanidins, can help reduce the effects of free radicals, support the strength of blood vessels and support healthy vision. OPCs can also help maintain normal histamine levels. Not limited to being just strong antioxidants, OPCs are also crucial in their role in supporting the circulatory system.
2. What are antioxidants, and why should I give them to my pets?
Antioxidants are nutrients that help maintain optimum health by protecting against free radicals. Antioxidants are found in the body as well as in many plants. Even cells that function normally generate large amounts of oxygen free radicals. Free radicals develop as byproducts of physiological processes that occur within the body. This process is largely responsible for the aging process. Certain factors in everyday life encourage an increase in the formation of free radicals. These factors include exercise, pollution and food. We need a "neutralizer" in our body to counteract these reactants and a strong and effective antioxidant is the best way to fight free radicals. It is becoming increasingly apparent to veterinarians that antioxidant supplementation could very well provide optimal health support for dogs and cats. Pets could benefit from a "neutralizer" operating in their systems that fight free radicals. A strong antioxidant is the best way to fight free radicals.
3. What is a bioflavonoid?
Bioflavonoids are complex organic plant compounds. Plants and fruits differ in colors based on the specific bioflavonoids they contain. An increasing number of clinical studies have shown how bioflavonoids support health. Bioflavonoids and OPCs play a key role in supporting cardiovascular health and maintaining vascular integrity. Bioflavonoids have been shown to support healthy circulation and cell vitality. Normal collagen renewal is promoted, which supports firmness of the skin, joint cartilage and connective tissue.
