A vitamin is an organic compound that is essential for an organism, although only in limited amount. Since the body is not always capable of producing the sufficient amount of vitamins, vitamins are also needed in the form of nutrients. Vitamins are classified according to their biological and chemical activity, not their structure. Our body can produce some vitamins under certain circumstances. Regarding humans, the link between Vitamin-D and sunshine exemplifies the above mentioned phenomenon. Not all substances have the same effect on every living organism. A substance might serve as vitamin for one, but not for the other. Vitamin-C is a good example for this, because most animals can produce it. Essential amino acids and essential fatty acids do not belong to vitamins, because they are needed in high quantities. So far, the number of vitamins acknowledged by science has decreased to 13.In general, a well-balanced diet cover the body’s vitamin needs. However, when putting a dietary together, one should not only aim that the raw material of the food should be rich in vitamins, but one should also take into consideration the fact that during cooking – especially during heating – 10% to 50% of vitamins might be lost.
According to their solubility, vitamins can be categorized as:
Fat-soluble vitamins (A, D, E, K)
Water-soluble vitamins (B, C, H, P)
There is no “chemical relation” between the members of the two above mentioned groups; moreover, there is no such relation between water-soluble B and C vitamins either. For the body, both groups bear the same importance via boosting its protection mechanism. Interestingly, they are mainly illnesses caused by vitamin deficiency which shed light on the physiological effects of vitamins.The quantity and the proportion of vitamins are key factors in a healthy diet. Multivitamin products contain the necessary vitamins and sometimes even minerals in the right combination, so further supplement is needed only in extreme cases.

These products are the classical multivitamins whose daily dose covers a moderately active person’s vitamin requirement.
In many cases, a single pill cannot provide the necessary amount of vitamins and minerals for athletes, not only because of the limitations of pill size, but also because of the different technologies how different components are made (e.g. compressed tablets, capsules, softgels). Vitamin packs are products which guarantee athletes’ increased needs by an assortment of vitamins in individual packets.
