The daily requirement of Vitamin E is in the range of 3-12 mg. Much more than this is available in normal diet, particularly in cereals, eggs, oil etc. Most commercial preparations contain 400 mg. Naturally overuse leads to side effects such as gastro-intestinal disturbances, fatigue, weakness etc.
