Vitamin E has something to do with the reproductive functions of the body. It also has some effect upon the muscles, and perhaps even on the heart. Many claims concerning the benefits supposed to be derived from vitamin E have been made, but the fundamental action of this vitamin is still not entirely proved.

Vitamin E is found chiefly in whole-grain cereals, green vegetables, olive oil, coconut oil, and other vegetable oils. Some doctors prescribe vitamin E for certain heart conditions, but others are not convinced of its value. There is no harm in its use.
