The dose matters: why not all vitamins are equally useful and how to choose the ones that are right for you

At the beginning of spring, sales of vitamin complexes increase. We all notice brittle nails, dull hair, dehydrated skin or rashes, drowsiness, fatigue — in such cases, it is customary to talk about beriberi. You can’t get rid of it just by eating right and sleeping well. And before you buy a multi-complex at a pharmacy, you should consult with a specialist. Otherwise, either money is wasted, or even worse – treatment of beriberi can cause other, more serious diseases.
Natural and synthetic
RAW-vitamins, or raw (natural) are easier to digest by the body, respectively shorten the course of treatment and have a more positive effect. ​ Synthetic vitamins are more affordable, but they are much less useful, because the chemical composition of their components is almost not associated with the body’s organics, they are poorly digested. ​It is also worth understanding that after a month of using synthesized vitamin complexes, the body almost loses the ability to absorb vitamins from food.​​ ​ ​Therefore, when choosing the latter, you need to pay attention to the composition, giving preference to the naturalness of the components and the body’s needs for certain groups of vitamins.
What is important to remember
There is an opinion that dry skin indicates a lack of vitamins A, B, C, but in the heating season, when the air in the room is dry, or with insufficient use of liquid, hard water from the tap, incorrect selection of care cosmetics or a sharp temperature difference-dry skin is quite a natural phenomenon, and excessive use of vitamin complexes can only harm the body. ​

Weight gain, weakness, and impaired mental performance are attributed to a lack of vitamin C,but this is not the correct definition. Since all these symptoms may indicate a completely different problem, for example, with the thyroid gland. Before making a decision to undergo a vitamin course of treatment, you should consult a specialist for advice. ​An endocrinologist can correctly determine which vitamins your body needs and prescribe a course of administration in the correct doses.

What is dangerous about an overabundance of vitamins
“Excess of vitamins, which is called hypervitaminosis, is a dangerous consequence for the body and can lead to increased excitability, tachycardia, arrhythmia, allergic reactions, dissomnia, nausea, persistent headaches. For example, an overdose of vitamin B1 can cause anaphylactic shock, B3-lead to muscle pain and disorders of the cardiovascular system, an excess of B6 leads to confusion and increased acidity of gastric secretions, D — arrhythmia, kidney failure, hypertension. Excessive amounts of vitamin A can cause nausea, vomiting, photophobia, muscle and joint pain, and diarrhea. Excess vitamin C also leads to nausea, flatulence, vomiting, intestinal spasms, and other more severe consequences.​ ​What tests should I take?

Based on this, to determine the necessary course of taking vitamin complexes, a specialist will assign you a clinical blood test, and already focusing:

on coagulability,
white blood cell level,
hemoglobin’s,
cholesterol and ESR (the rate of settling of red blood cells) will understand what exactly is missing from the body.
You can also pass:

biochemical blood test,
tests for vitamin status,
and the content of trace elements in the body. ​Then, based on the indicators of weight, gender and age, the direction of treatment or prevention of admission, the doctor is able to correctly assign the frequency of admission, the time frame and choose the right vitamin complex.”

Who is more suitable?
“Everyone knows that pregnant women and the elderly need vitamins. As a rule, in the case of pregnancy, the body’s need for certain trace elements increases by 30%. In this case, there is a need for additional intake of b vitamins, in particular B9, which promotes active cell division. Vitamin A takes an active part in the formation of the skeleton, E — contributes to the formation of the placenta, C — forms the immune system of the fetus, and other trace elements are needed to prevent the risk of anemia in a pregnant woman and improve the formation of the thyroid gland in a child.

In old age, vitamins become necessary due to the physiological characteristics of the body, in particular: a decrease in the volume of water and minerals, a decrease in the number of mitochondria in cells that produce energy, oxygen deficiency, slowing down protein, fat and carbohydrate metabolism. Naturally, in the presence of all these factors and not quite proper nutrition and lifestyle, most people of retirement age need all 13 vitamins that contribute to the normal functioning of the body. Among them, there are 5 main ones: A B C E and D. They should be present in the complexes chosen by the elderly.”
