"Vitamins are substances that your body needs to grow and develop normally. There are 13 vitamins your body needs. They are vitamins A, C, D, E, K and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B-6, vitamin B-12 and folate). You can usually get all your vitamins from the foods you eat. Your body can also make vitamins D and K. People who eat a vegetarian diet may need to take a vitamin B12 supplement.
Each vitamin has specific jobs. If you have low levels of certain vitamins, you may develop a deficiency disease. For example, if you don't get enough vitamin D, you could develop rickets. Some vitamins may help prevent medical problems. Vitamin A prevents night blindness.
The best way to get enough vitamins is to eat a balanced diet with a variety of foods. In some cases, you may need to take a daily multivitamin for optimal health. However, high doses of some vitamins can make you sick."
Vitamin E is a fat-soluble vitamin found in many foods, fats, and oils. It is also an antioxidant, a substance that may help prevent damage to the body's cells. Antioxidants may provide protection against serious diseases including heart disease and cancer. Vitamin E is also important in helping your body make red blood cells, and it helps the body to use vitamin K. People who can't absorb fat properly may develop vitamin E deficiency. Symptoms of serious vitamin E deficiency include:
1. Muscle weakness
2. Loss of muscle mass
3. Abnormal eye movements
4. Vision problems
5. Unsteady walking
