Kentucky Equine Research (KER) developed EO-3, a potent marine-derived oil that is rich in omega-3 fatty acids, to help combat the shortcomings of your horse's heavy grain mix and hay diet.  Used as a top dressing on your horse's feed, EO-3 is great for all classes and levels of horses to help improve the omega-3 and omega-6 diet ratio. This supplement has a mild apple flavor with a minty essence for palatability.
