Organisms require nutrients that come in the form of organic compounds, like vitamins. In laymen terms, a vitamin is an organic chemical compound. Vitamins are essential nutrients that our body cannot produce itself or cannot synthesize in sufficient quantities. Because of this, we must obtain these essential nutrients through other sources. One way we can do this is of course to increase our intake of fruits and vegetables, but most of us simply do not have the time to eat all of these foods. Luckily for us we have help in the form of vitamin supplements. Vitamins in tablet form help to balance out our body, and multivitamins are a great way to get a hefty dose of the vitamins and minerals we need to be healthy, energized and above all happy.

Vitamins are grouped based upon their biological and chemical activity. Each vitamin refers to the number of vitamer compounds that are all associated with biological activity respective to a certain vitamin.

What's a Vitamer?
Different vitamins have a different number of chemical substances—most vitamins have more than one chemical substance—and these substances are known as vitamers. Vitamers are an indication of the biological activity associated with each chemical compound. This is why there are different vitamins, such as vitamin A and the vitamin B's.
