Vitamin E is considered the most important antioxidant and works closely with selenium to protect the body from the oxidative stress of exercise and illness. Found in high amounts in fresh pasture, levels begin to decay the moment pasture is cut for hay. That is why any horse that does not have access to grass, regardless of its activity level or health, would be a candidate for vitamin E supplementation. Horses are not very efficient in storing vitamin E and deficiency may be accelerated if the diet is deficient in selenium.
