Vitamin E is a potent antioxidant primarily found in green pasture grass that plays a role in muscle atrophy (wasting) and neurodegeneration in horses. As pasture lands become increasingly more limited and more horses are housed on less acreage, vitamin E deficiency becomes a real problem.

Stephanie Valberg, DVM, PhD, Dipl.
