Majority of us are doing our best to always have a well-balanced diet so as to keep ourselves fit, healthy and strong. But no matter how much we may eat to get enough of the vitamins and minerals we need, we cannot solely rely on natural sources like food, fruits, vegetables and the like. No matter how much we stick to what is natural with no preservatives, one way or another it loses essential vitamins. Take for example freshly picked vegetables. By the time it reaches our mouth, it may have gone through the process of being transported all the way to the supermarket, sitting on the store shelf, being bought, sleeping inside your refrigerator for some time and eventually being cooked before being eaten. By the time you eat it, only a fraction of the vitamins is left for your body to absorb.

You also have to take into consideration that majority of the world's population consume processed food packed with preservatives. The changing lifestyles over the years have made people rely on food to go like fast foods and junk food.

Our body needs vitamins to function properly so it is important that we replenish it daily. Our body requires vitamins to prevent from getting weak, sick and contracting diseases. We also need vitamins to boost our immune system. We need vitamins to help battle against the viruses that may be contaminating our body when we get sick. When we cut ourselves, we need vitamins to help our body repair the damaged tissue. Every little thing that happens inside and outside our bodies in one way or another requires a certain vitamin.

We may exert the extra effort to eat the right kind of food but we may not be getting the vitamins needed in appropriate amounts. How can the body and the vitamins work together to convert the food that we are eating into energy if we don't get the daily need of vitamins? Because of these reasons we need to take supplemental vitamins or better yet multivitamins to enable our body to get its needed daily dose of vitamins. This goes especially for those vitamins that are water soluble like vitamin C and the B vitamins which need to be replenished every day because what the body does with these vitamins is that the quantity not needed is just discharged by the body when you urinate.
