Megaderm is a tasty supplementary animal feed based on essential fatty acids and vitamin E. It is used to promote healthy skin and coat. Megaderm contains both omega-6 and omega-3 essential fatty acids in a 5:1 ratio. The omega-6 fatty acids are derived from sunflower and evening primrose oil. These sources are very rich in linoleic acid. Moreover, evening primrose oil is one of the few oils that contains gamma-linolenic acid. The omega-3 fatty acids are derived from coldwater fish. These essential fatty acids play an important role in maintaining healthy skin and coat. Megaderm can be easily added to a dog or cat's regular food thanks to its dosing system.
