iO Cod Liver Oil is a fat-soluble supplementary source of Vitamins A and D. Cod liver oil is a superb source of decosaheaxenoic acid, which is also known as DHA, and eicosapentaenoic acid, which is also known as EPA. This maintains equine joint flexibility, promotes a healthy glossy coat, boosts your horses immune system, can work as an anti-inflammatory, has anti-allergic properties and encourages a strong metabolism. iO Cod Liver Oil is a special veterinary grade of oil that has not gone through heat treated deodourisation, that many other Cod Liver oils are subject to and allows for maximum naturally occurring Vitamin A and D. iO Cod Liver Oil can also be used for many other animals with joint and bone pain, inflammed areas and dull coats.
