Vitamins
Vitamins are involved in almost allbiochemical processes of our body. Vitamins are catalysts of metabolic processes and often perform a regulatory function in the body. Vitamins are not produced by the body, so they should come with food or in the form of vitamin preparations.





In the winter season due to lack of fresh vegetablesand fruit, the lack of vitamins and mineral micro- and macro-elements is especially acute. Therefore, you can and should take various vitamin preparations. All vitamin preparations can be divided into two main groups: one-component vitamin preparations and multivitamin preparations.

One-component preparations, i.e. those that contain only one vitamin are usually prescribed by a doctor if there is a shortage of this vitamin in the body. For example, vitamins A, C, D, E, etc. Polyvitamin preparations contain a whole complex of vitamins in a single dose of the drug. Often multivitamin preparations are enriched with micro- and macro elements (calcium, magnesium).

The body needs these vitamins:
