Most vitamins are actually surprisingly simple configurations of basic elements such as carbon, hydrogen, oxygen, and nitrogen, and they can be flawlessly duplicated in the laboratory. Your body cannot discern any difference between, for instance, ascorbic acid (synthetic vitamin C) and rose hips (natural vitamin C) because the two have an identical chemical makeup. The argument for natural vitamin supplements is faulty - although lucrative. If you shop around for vitamins or vitamin-fortified foods, you will notice that the natural vitamins usually cost considerably more than the synthetic.
However, any vitamin supplement, whether natural or synthetic, is no substitute for a balanced diet. Scientists may be able to manufacture the vitamins that have so far been identified, but they have neither the knowledge nor technology to manufacture all the subtle components of a complete diet.
