Vitamins are essential organic compounds required for the healthy function of living organisms.
The biological activity of the organic compounds get them classified into vitamin groups.
In many cases a vitamin may denote a group of organic compounds having similar biological activity and may have different chemical structures.

The essential nutrients like carbohydrates, proteins, fatty acids and dietary minerals are not to be confused and grouped with vitamins. Vitamins function in different roles like antioxidants, enzymes, co-enzymes, hormones and catalysts. Though the requirement of vitamins and their sources in food were enlisted long back now they are being synthesized commercially. Vitamins are classified into fat soluble and water soluble vitamins.

In human beings of 13 vitamins nine are water soluble and four are fat soluble. The fat soluble vitamins (A, D, E and K ) are absorbed, stored and accumulated in the body, where as water soluble vitamins are readily absorbed and readily excreted. This property of these vitamins requires our consistent intake. The deficiency of vitamins can result in a number of maladies. The primary deficiency occurs when a person is short of vitamins in his food.

In the secondary deficiency due other external factors a person is not able to absorb utilize vitamins. Unless the core problem is resolved the secondary deficiency can lead to irreparable damages. The over dosage of vitamins can also cause problems. This is experienced when vitamins are taken in a supplementary form like tablets. This can be corrected by reducing the dosage.Visit http://www.thedynamicnature.com/vitamins/vitamins.html for more information.
