How to take vitamins?

As I stated in my previous post, vitamins are substances that cannot be synthesized by the human body. So we have to add vitamin rich food items in our diet. And doctors say most diseases are caused by vitamin deficiencies and it is necessary to take the right vitamins in right proportions and we all know prevention is better than cure! But we cannot expect all to take to a perfectly balanced diet and this may change depending on the availability of food and many other criteria. In such cases vitamins can be taken in the form of tonics or pills. Nowadays there are several top brands providing vitamin pills and some pills like the vitamin B pills have in fact become one among the household items for many.
