Vitamins Chart: Classification, Types, Sources and Functions

Whenever you hear the word “Vitamins”, don’t you tend to relate it with a healthy diet and good health? This is exactly what vitamin does. You must have seen food manufacturers bragging about the vitamin content in their food. The food boxes have bold lettering of “Vitamins” to convince you that whatever you’re eating is healthy and good for you.

Vitamins are the organic compounds that are very essential for the body in order to make it function properly and smoothly. The foods that you eat provide you vitamins, but you need to know which food provides which vitamin and in what quantity. Later, in the article, we have a vitamin list presenting the types of vitamins, classification, sources and functions. Note that there happens to be a different vitamin chart according to age. However, the basic vitamin chart has been presented here.
