In principle, the question is deeply relevant and precisely for the broad masses of the population. Why? It all starts from the stage of pregnancy, when the mother's body, receiving regular food, is unable to form a fully functioning future organism.

Further. Yes, now all his life an ordinary average person is forced to additionally take vitamins and, what is even more important, micro- and macroelements
But - WHAT bioelements? Since the current civilization is following the path of technocratic development, the methods of working with health are appropriate, that is, based on the products of chemical production. Taking synthetic medicines, synthetic vitamins and supposedly "bio" additives will not lead to anything good. Details, again, in the aforementioned MK
For each person, an individual selection of bioelements necessary for his body is required. Although there is a general, basic set that any person needs
Once in a pharmacy I heard a pharmacist recommend Geksavit. It costs a penny and was developed specifically for daily use without mandatory preliminary clinical diagnosis. I bought it and tried it - I highly recommend it. I also like Supradin very much. You will feel the effect of taking it within 3-5 days. But it is better to consult a therapist.
The average person should regularly take vitamins that are not synthesized by the body: ascorbic acid, vitamin A, vitamin E, the human body does not produce at all, cyanocobalamin, folic acid and others are synthesized by the intestinal microbial flora, but not always in sufficient quantities, and must additionally come with food or dietary supplements. It is worth paying attention to your diet: if it is not balanced enough, then dietary supplements with vitamins will replenish everything you need. For example, if you eat a little fish and seafood, then you need to provide the body with an additional intake of omega-3 fatty acid. It is from fatty acids that the body synthesizes other biologically active compounds that take part in all life processes.
By my example, I will say that there are several vitamins from which I get the maximum effect:
In such matters I trust only WHO (World Health Organization) and evidence-based medicine.
I think that multivitamin complexes are not always needed. But in our latitudes there is one vitamin that we give to children and drink ourselves - this is vitamin D.
The modern concept of a healthy lifestyle calls for caution with artificial food additives. The ideal option is to get vitamins as part of a balanced diet. In a healthy person, simple nutritional rules will form a sufficient content of essential vitamins (or rather, their active, "working" forms) in the body. The only indication for taking vitamins is a lack of one or more of them - vitamin deficiency. It can be detected by indirect, clinical signs, but it is more reliable to determine the level of vitamins in the blood by biochemical tests. The doctor can prescribe tests and correctly assess the body's need for vitamins. I note that in northern countries, especially in winter, vitamin D deficiency is most often observed. However, an adult should not take it just like that, without a deficiency confirmed by a doctor. In addition, vegans are more likely to develop vitamin B12 deficiencies over time, which can have dire health consequences. This group of people, accordingly, is recommended to take drugs with this vitamin.
