Humans can’t live without vitamins. They are important for the normal growth and development of human organism. Especially important are the vitamins for children organisms. Their growth and normal development require vitamins and minerals at certain periods. These vitamins are vital, because they are responsible for chemical reactions that produce bones, muscles, skin and other things.
A child cannot develop normally if there is lack of these nutrients; the shortage in vitamins can cause serious damage to health.
Vitamins are naturally taken with food, but some of them are produced by microorganisms in the intestine, for instance, vitamin K and biotin. Some vitamins are produced by our organism with the help of natural factors – D is made in skin by means of ultraviolet. Humans produce some vitamins from food they eat. Beta carotene transforms into vitamin A.
Even when our organism stops growing we need vitamins. They remain vital nutrients for the healthy keeping of the cells, tissues, and organs. Vitamins are also essential for using chemical energy, proteins and fats.
