Vitamin E & Folic Acid from AniMed is commonly used for horses in conjunction with EPM treatment to provide supplemental essential vitamins. Folic Acid is essential for red blood cell health and can be used to help control anemia. It should be given when horses are receiving medicine that inhibits Folic Acid production. Vitamin E helps support the normal function of your horse’s nervous system, muscular system, circulatory system, and immune system. This supplement also contains B-complex vitamins, which can be beneficial to horses under stress.
