We have all heard about vitamins and how important they are for bodies, but, do we really know what vitamins really are? And why is it so important for us? Vitamins are an essential part of our lives, without it, we would not be healthy human beings.
Vitamins came about in the early 1900’s when a famous English scientist, Sir Frederick Gowland Hopkins fed some rats on a mixture which contained carbohydrate, fat, protein and minerals, in a few weeks the rats were dead. He gave a second group of rats in the same mixed with some milk and they didn’t die, he concluded that the milk contained something special and it was called vitamins.
Vitamins are a collection of organic substances that are needed in our diet, and each has a specific purpose, but overall, their function is to help control the chemical reactions which take place in our bodies, and is found particularly in foods. If any of these vitamins are missing from our diet we can die like the rats.

One such vitamin that plays an integral role in our everyday lives is Vitamin A, a fat soluble vitamin which is important especially for our eyes as many of us may already know, it protects their surface and helps us to see in dim light.
