Here's the thing, there isn't a single task that vitamins perform, there are quite a few of them that if not every single thing that happens inside the four walls of your body. You may think of them as being similar to catalysts or the major components that make everything possible in your body because they perform the role of both. Let us take the example of vitamin D, if someone is short on that, he may be prone to developing rickets or softening of bones by other means. One might think that it is only a vitamin but in reality, it plays quite an evident role in the functioning of your everyday tasks. 

Vitamins are complex chemicals that play an essential role in the normal functioning of the human body and, with a few exceptions, cannot be synthesized by it. They are found in most naturally occurring foods and are absolutely necessary for the growth, vitality and general well-being of our body.Many vitamins are needed in very small amounts, but they play a very important role in most chemical reactions in the body.  They are not food, but neither are they food supplements, nor do they provide energy, although no human being can live without vitamins. Many of these cell reactions are carried out by enzymes, each other kind of enzyme being responsible for carrying out particular chemical reactions within the body.

Vitamins are essential for good health because they play a vital role in maintaining various bodily functions, such as metabolism, growth, and development. They also help to boost the immune system, promote healthy skin and eyes, and support the production of red blood cells. Without enough of certain vitamins, the body may be more susceptible to disease and illness. For example, a deficiency in vitamin C can lead to scurvy, while a lack of vitamin D can lead to rickets. It's important to get a balance of different vitamins through a healthy diet, or by taking supplements as needed. 

if we take the recommended daily amount of a vitamin, it can help to improve your overall health and prevent deficiencies. For example, taking vitamin C can help to boost your immune system and promote healthy skin, while taking vitamin D can help to maintain strong bones and teeth.
