Vitamin E: why it’s crucial for health.
Vitamin E is essential for your horse. It helps eliminate damaging free radicals in his body, protects cells, supports his immune system, and assists with nerve and muscle function. A deficiency can cause muscle loss, toe dragging, and overall weakness. Fresh pasture is the best source of E; if your horse gets plenty of green grass, he’s probably getting enough of the vitamin. Consider a supplement if your horse has little or no pasture turnout, is a hard-working athlete or pregnant mare, or has certain neurological or muscular diseases (check with your vet; a blood test is the best way to assess levels).
Grazing on green grass for several hours or more every day will assure that most horses receive adequate amounts of vitamin E.
