What are Vitamins ?

Vitamins are organic food substances that are found only in living things, i.e. plants and animals. They are essential for our bodies to function properly, for growth, energy and for our general well-being. With very few exceptions the human body cannot manufacture or synthesize vitamins. They must be supplied in our diet or in man-made dietary supplements. Some people believe that vitamins can replace food, but that is incorrect. In fact, vitamins cannot be absorbed without also taking food. That is why it is best to take them in meal. Synthetic vitamin supplements can be of varying quality, so it is a good idea to get your supplements from a reliable source.
