A. Vitamins are substances that are found in many of the foods we eat. Your body needs vitamins to work properly, which makes them some really important substances! Your body uses vitamins to do many things, like help you grow and develop. It needs vitamins to help your blood clot when you get a cut. Some vitamins help us make energy. Vitamins are even involved in making sure you can see in color, the world would look black and white without them! Think of vitamins kind of like the fluids in your car. If you have no oil (vitamins) in your car, it does not matter how much gasoline (calories) you put in your car, your car will not run. For this reason, it is critically important to ensure a proper supply of vitamins in your car. Unlike the oil in your car, many vitamins are purged from your body daily. A high-quality liquid multivitamin will replenish lost vitamins and minerals. For the full article: http://www.vitamins-nutrition.org/vitamins/why-take-vitamins.html Hope this helps.
