Are Vitamins Really Good For You?
Vitamin complexes are one of the most popular drugs: probably, in our society there is no person who has not heard about the benefits of vitamins and has never taken them. The more vitamins – the better, we believe and, as it turned out, we are cruelly mistaken.
Are they required by the body, is the innocuous craze for multivitamin complexes and whether it is possible to do without vitamins?
Let’s try to figure it out.
First we turn to the facts. Vitamins are substances that the body needs in microscopic quantities in order to carry out its functions. In the absence of vitamins – even when all other substances are present in the diet – the body begins to malfunction and the person becomes ill.
In normal vitamins enter the body with food. Different foods contain different vitamins, and this is one of the reasons that the diet should be diverse and include different food groups.
Vitamins are unstable and easily destroyed by heat treatment. That is why part of the diet must necessarily be represented by fresh vegetables and fruits – products containing the greatest amount of vitamins.
Is it true that the need for vitamins cannot be satisfied with food?
In the twentieth century, it was suggested that it is impossible to obtain the amount of vitamins required by the body only from food, so they need to be additionally taken to prevent vitamin A deficiency – the state of vitamin deficiency.
It was believed that vitamin deficiency is a constant companion of modern man, contributing, in turn, to weakening of immunity and the development of many diseases. This thesis was warmly supported by pharmaceutical concerns, and after a while the triumphant march of vitamin complexes across the planet began.
Vitamins are prescribed for almost any disease, with the exception of hypervitaminosis (along the way it turned out: if you overdo it too much, it happens). It is widely believed that vitamins always help the body (at least they do not harm). But is it?
Decades of the vitamin boom have allowed to accumulate clinical experience, and now doctors are increasingly claiming that the total need for additional fortification is not true. They say that vitamin complexes are in most cases useless, and in some cases harmful, and, as it turned out, this view is much more true than the fact that vitamins need to be taken almost constantly.
Conducted by several independent centers, studies have shown that the doses of vitamins that were considered essential for vital activity are greatly overestimated. In fact, vitamins from food are sufficient to meet all the needs of the body – provided that the diet is varied, contains different food groups and contains fresh vegetables and fruits.
In most cases, vitamin deficiency in a modern person is not connected with the lack of vitamins in food, but with problems of their absorption in the body (for example, in violation of the process of absorption in the intestine, which occurs in many intestinal pathologies).
In the course of other studies, it was established that synthetic vitamins are absorbed by the body by no more than 5%, therefore, their effective effect on the body cannot be said.
What you need to know about vitamin complexes?
Vitamins, either individually or in combination with each other, do not protect against colds. “Drink vitamins so as not to get sick” is not a brilliant idea. One of the proofs is the fact that the peak of seasonal morbidity falls on late autumn, that is, at a time when the body is maximally saturated with vitamins after summer and early autumn rich in fruits. If vitamins really protected from colds, nobody would have heard about autumn-winter outbreaks of respiratory diseases, their peak would be in the spring, when the content of vitamins in food is minimal.
- Reception of vitamin complexes is not able to protect against cancer. Moreover, it is absolutely unequivocally established that certain vitamins (for example, vitamins A, E, C) promote the growth of malignant tumors.
- Synthetic (in other words, created in the laboratory, and not received from food) vitamins are highly allergenic. In particular, some pediatricians associate general allergies in modern babies with the fact that many women take multivitamin complexes during pregnancy.

When are vitamins necessary?
Nevertheless, there are situations when taking vitamins is vital. There are two such states: hypo-and avitaminosis, that is, a reduced amount of certain vitamins in the body and their complete absence. Usually we are talking about one or two vitamins. For example, in alcoholism, the absorption of vitamin B1 is impaired, therefore, in the treatment of alcoholism, it is prescribed, and injections, and not in the form of a “vitamin”, which would be meaningless.
Travelers to antiquity often suffered from C-avitaminosis. People from poor countries, whose traditional food is refined white rice, often get beriberi (so called B1-avitaminosis), and those who eat mainly corn – pellagra (this is PP-avitaminosis).
Young children living in areas with low insolation, that is, with a small number of sunny days per year, have cases of hypovitaminosis D, which is the cause of rickets.
Hypovitaminosis is diagnosed in residents of the Far North (due to vitamin ration poverty), as well as in all those who eat foods that contain little or no vitamins (fast food, junk food, food made by industrial means).
People practicing veganism (veganism) often show signs of a lack of vitamin B12, which is mainly found in meat and dairy products.
In all these situations, you need to take vitamins. But in such cases, they perform a therapeutic function, are prescribed by the doctor in strictly calculated doses after the diagnosis, and therefore we are not talking about fashionable vitamin-mineral complexes.
