EPM is a protozoa that stays in the body forever once it is contracted and can only be managed. Normal EPM treatments only target the protozoa in the body but not in the blood stream. This is why horses tend to relapse. EPM Formula targets the protozoa in the blood stream. Through Nitric Oxide pathways, we are able to help the horse’s body lower the amount of protozoa numbers to a manageable level where relapse is unlikely.
