Vitamins are a necessary component of a healthy diet. They are considered essential nutrients because our bodies either do not make them, or do not make enough of them.

They are essential for normal body functions like cell growth, blood cell production, hormone and enzyme synthesis, energy metabolism, and proper functioning of body systems, including the immune system, nervous system, circulatory system, and reproductive system.

Since no single food contains all the vitamins you need, you must obtain them through a variety of foods. You can take a pill that contains vitamins, but it is always preferable to get them the natural way.

The reason is twofold. If you take a supplement because you assume your diet is poor, you may not be supplementing the right nutrients. More importantly, getting your vitamins by eating healthy foods provides the body with many other nutrients necessary for good health, including fiber, carbohydrates, protein, and water.
