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, inflamed areas and dull coats. Always seek advice from your local veterinary professional.
