Most of the vitamins have been artificially synthesized. Some of vitamins are soluble in water and others are fat-soluble. Some vitamins are synthesized in the body. Some members of vitamin B complex are synthesized by microorganisms in the intestinal tract. Vitamins are partly destroyed and are partly excreted.

Hence, the total daily requirement is usually very small.
