The official jury is still out, but studies have shown no problems up
to approx. 1 cup of oil per day. After 2 cups, some studies say you
should supplement E, and just as many say there is no problem unless
the horse is maintained on poor hay or scrubby pasture with low grain
ration. At that situation, you will probably have more than just a
Vitamin E problem. Lynn
