Patient Education

Vitamin E (Alpha-Tocopherol)


Vitamin E is used as a dietary supplement when the amount of vitamin E taken in the diet is not enough. People most at risk for vitamin E deficiency are those with a limited variety of food in their diet and people with Crohn's disease (a condition in which the body attacks the lining of the digestive tract, causing pain, diarrhea, weight loss, and fever), cystic fibrosis (an inborn disease that causes problems with breathing, digestion, and reproduction), or who have gastrointestinal (GI) malabsorption problems (problems absorbing food). Vitamin E is also used to treat vitamin E deficiency in those at risk due to certain diseases and conditions. Vitamin E is in a class of medications called antioxidants. It is needed by the body to support the immune system and for blood clotting. It works as an antioxidant to protect your cells against free radicals.
