Nutritional deficiencies are common. Everybody gets different amounts of minerals in their water, for instance, and everybody drinks different amounts of water. A simple one-a-day supplement will handle a lot of that for you. Exercise also puts a strain on your system that increases the need for certain vitamins and minerals. If you want to add supplements, read up what each vitamin and mineral does. Most vitamins are water-soluble, so you'll just pee away the extra, so they won't generally hurt much even if you have too much. Don't take too much of the fat-soluble ones, as they get stored up in your body, and too much vitamin A especially can be toxic. In other words, you can increase your intake of some vitamins and minerals, but not all. Be sure to do some reading, and supplement carefully and slowly. Deciding to take a lot more niacin, for example, can lead to some panicky moments. Break in increased dosages of anything into your diet slowly and carefully. There's no hurry; you got along without them before.
