Fake medicine: Why you shouldn’t drink dietary supplements 

The temptation to IMPROVE YOUR HEALTH by buying a bottle of multivitamins or biologically active additives (dietary supplements) in a pharmacy, store or online, arises easily – especially when it seems that these funds will definitely not cause harm. They are often presented as medicines, although they have nothing to do with the latter – neither in composition, nor in terms of requirements for quality control and registration. Let’s figure out why dietary supplements don’t go out of style and how much money people spend on supplements they don’t need.

How vitamins were discovered

In the mid-19th century, scientists began to investigate how nutrition is related to health. Technology made it possible to extract fats, proteins, carbohydrates, water and mineral salts (also called minerals) from food – it seemed that it was possible to create an ideal balance of these substances and make a real scientific breakthrough. Usually experiments were carried out in the following way: food, usual for experimental animals, was processed chemically, extracting known nutrients. Then these substances were fed to animals and the parameters of growth and development were measured .

One of these researchers was the Russian scientist Nikolai Lunin, who worked in the laboratory of Gustav Bunge in the city ​​of Dorpat (present-day Tartu in Estonia). In 1881, he conducted an experiment: he took two groups of experimental mice, one he fed with ordinary cow’s milk, and the second with a mixture of proteins, fats, carbohydrates and mineral salts, completely corresponding in proportion to the milk offered to the first group. As a result of the experiment, a group of mice that received the mixture died. Lunin concluded that for the normal functioning of the body, some other components are needed.

By Unfortunately, Lunin colleagues were unable to replicate the results of this experiment – in their versions of the second group of mice survived. Much later it became clear that initially Lunin used cane sugar, and his colleagues – poorly refined milk; in the latter, vitamin B12 remained, thanks to which the mice survived. But at that time no one knew about this, and Lunin’s works were forgotten for some time.

Another scientist, Dutchman Christian Eikman, studied beriberi disease (a disease of the nervous system caused by vitamin B1 deficiency. – Ed.) While in the Dutch East Indies. He found that when chickens and pigeons were fed peeled rice, they developed symptoms similar to beriberi — they were unable to move, fly, or even stand. Eikman proved that the casing of rice, which is removed during the grinding process , prevents and treats these symptoms in birds.

The term “vitamin” was coined by the Polish scientist Kazimierz Funk, who studied diseases such as scurvy, beriberi, rickets and pellagra. Funk isolated a chemical concentrate contained in the shell of rice grains. Funk added this substance to the diet of pigeons eating refined rice, and they did not develop symptoms from the nervous system. Assuming that the found substance belongs to the class of amines, Funk introduced the concept of “vitamin”, from the Latin vita – “life” and amine – “amine”. Subsequently, it was proved that substances with similar functions can belong to different chemical classes, and the word vitamine became vitamin.

Since then, vitamins have been well studied and carefully classified not only by chemical composition, but also by many other characteristics. On Today it is known that the vitamins needed by the body in tiny amounts not only to prevent certain diseases, but and for normal growth and development.

In 1994, the United States introduced the Law on Food Additives: dietary supplements have ceased to be classified as drugs, but have become precisely “additions” to food. Since the strict rules for studying and preparing for registration now did not apply to dietary supplements, their manufacturers have the opportunity to attribute any magical properties to them , claim health benefits and even promise healing of diseases. After that, both the American and the global dietary supplement industry skyrocketed .

The fact that dietary supplements do not belong to the categories of drugs and food makes it possible for manufacturers to hide their composition – it may not be indicated completely or not correspond to the declared one. In 2017, Rossiyskaya Gazeta reported that Rospotrebnadzor withdrew several batches of Chinese-made dietary supplements from sale and stated that some of them could harm health and be life-threatening. We have already said that “sports” supplements can be effective for losing weight or gaining muscle mass for the simple reason that they contain prohibited substances, of course, not declared on the label.

In 2002, the European Union issued special rules for the circulation of dietary supplements – only complexes that are safe in the indicated doses can be sold without a prescription. In Russia, it is forbidden to advertise dietary supplements as medicines; the law also has a number of requirements for advertising of food additives – in particular, it should not “contain references to specific cases of curing people, improving their condition as a result of the use of such additives.” Other laws issued in the same year tightened the impact on distributors of “substandard and unregistered drugs, medical devices and counterfeit dietary supplements.” However , dietary supplements sold in Russia can be dangerous – especially since they are often distributed through channels such as Instagram, rather than through pharmacies.

In 2012, in the United States, Americans spent an average of $ 100 a month on dietary supplements – including adults and children. In 2017, 177 million packages of dietary supplements were sold in Russia – in monetary terms, this is 24.3 billion rubles.

Why are even good quality dietary supplements dangerous?

Let’s say you don’t buy anything through social networks, pay attention to the manufacturer’s reputation and bring multivitamins from European pharmacies. Unfortunately, even such a tactic can be harmful: there is more and more evidence that an excess of vitamins can contribute to the development of malignant tumors – in particular, the results of a number of studies on lung cancer indicate this . For those who play sports, vitamin support is also optional: the benefits of exercise are also associated with the so-called oxidative stress, during which free radicals are produced. Vitamin antioxidants can nullify this process, negating some of the benefits of exercise.

As doctors and scientists never tire of reminding , you can get all the necessary nutrients from a normal diet. At risk are only some groups – for example, vegans have a small risk of vitamin B12 deficiency, regular menstrual period may contribute to iron deficiency, many people have a lack of vitamin D, and in preparation for pregnancy in the first trimester folic acid is shown. Be that as it may, you should not prescribe vitamins and dietary supplements yourself, if you have any problems, it is better to consult a doctor.
