Vitamins are organic materials that are required in the body in trace amounts for metabolism processes. The fat-soluble vitamins are vitamins A, D, E and K while the water-soluble are the B group and C vitamins. A very important thing to emphasize is that vitamins are not macronutrients that release energy; however, without vitamins, energy metabolism does not occur blood will not clot, the immune system will not function, and bones and tissues will not develop properly.

The majority of vitamins are produced by the human organism in insufficient quantities; thus, they need to be received through foods or supplements. Lack of nutrients results in different ailments, the same way, negative effects of nutrients in large quantities are also observed in our bodies. Such a formulation is also behind the definition of the chemical structure, the fact that vitamins are required in small amounts yet they are essential and that they are derived from diet.
