Vitamins are essential, meaning that our body can not produce them itself. We need to supply them daily - in our diet or through supplements. Each vitamin fulfills its unique function in the metabolism.
The amount of vitamins required by the body lies in the order of few micrograms to a hundred milligrams per day and varies from one vitamin to the other. The requirement is additionally affected by factors such as stress, strenuous work out and diseases, but also by pregnancy and lactation. A deficit of only one of the vitamins can already impact the normal function of our body.
