Immune Support & EPM Supplements

Big Dee's has a large selection of Immune Support and EPM supplements to help aide your horse. Immune support can help horses with stressed immune systems or horses susceptible to illness from showing. Equine Protozoal Myeloecephalitis, or EPM, is a disease caused by the protozoa, Sarcoystis neurona which attacks the central nervous system of the horse causing muscle atrophy, asymmetry, loss of coordination, and several issues. If caught early, the EPM horse can be treated successfully, and maintained through supplements. Many of the supplements in this category also serve dual purposes and could be helpful for a wide range of horses under stress from training, competing or a changing environment. These types of horses could also benefit from a calming supplement.
