b    vitamins are a group of substances found in food. the body needs them for life and health. so naturally, many people are concerned for the question: am i getting enough vitamins, and am i getting the right kind?  even though very small amounts of each vitamin are enough for the needs of the body, the worry people have about vitamins has some basis. and this has something to do with their diet—the food they take in. a person eat in a good variety of foods gets all the vitamins now known to be needed (with the possible exception of vitamin d).  the problem is that there are many people who don’t choose foods wisely, don’t get enough variety, and don’t eat the basic foods they need to get their vitamins. so the answer to this questions is : no extra vitamins are taken in; the body simply gets rid of them. it is even harmful to put too much of certain vitamins into the body this has been found true of vitamin a and d when large amounts are taken in.
