Vitamins are substances that your body needs to grow and develop normally. There are 13 of these essential 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 to ensure that they are getting the vitamins usually found in meat.
Each vitamin has a specific job. If you have low levels of certain vitamins, you may develop a deficiency disease. Some vitamins may also help prevent medical problems. 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 may make you sick.
