What is Vitamin???

Vitamins are essentially substances made by plants with the help of sunlight or by lower forms of life such as bacteria; vitamins can also be created by animals or the human body!!!

Most of our vitamins come from plants.. Interestingly, the amount of a vitamin found in a given plant is always the same because the plant always makes just the right amount it needs to stay alive..

For example, the average size orange usually has about 85mg of Vitamin C..

Vitamins found in animal products such as eggs, are by-products of the plants  ingested by the animal or were created by bacteria.

Over the years, scientists have developed three criteria by which substance can be defined as a vitamin. If one of the three criteria is not satisfied, the substance in question is not considered a vitamin in the strictest scientific sense:-

1. Vitamin is a nutrien required in small amounts for normal body function.. Vitamins are not made in the body & must be supplied from an outside source..Even in those few circumtances where vitamins are made in the body; the process generally involves an important ingredient from outside the body, such as the bacteria normally found in our intestines..
2. A vitamin must be an organic chemical; that is, every vitamin has at least one carbon atom in its molecular structure..
3. There is a specific set of symptoms or a specific disease associated with a deficiency of each vitamin & it can be corrected by taking the appropriate amount of that vitamins..
