Why vitamin D is dangerous: why you shouldn't drink it without a doctor's prescription

Many people today believe that they need to consume vitamin D daily. This drug is credited with magical properties that will help avoid not only the blues, but also many health problems. But is it really what doctors think of vitamin D?

What is Vitamin D

According to doctors, vitamin D is not such, because it has the properties of a prohormone. It enters the human body from food, with dietary supplements or due to ultraviolet light. As a result of special transformations, it turns into the hormone calcitriol. Its task is to control the work of various body systems.

If you have enough vitamin D:

• calcium and phosphorus are well absorbed, which means that the skeletal system will be strong, and the skin - elastic;
• the reproductive system is working normally;
• the risk of developing atherosclerosis decreases;
• pressure decreases;
• immunity increases;
• metabolism improves.

Some foreign doctors claim that a lack of vitamin D increases the risk of developing cancer and other diseases. But another group of scientists refutes such conclusions, since it is impossible to say which appeared earlier - oncology or prohormone deficiency.

How to get vitamin D

This vitamin is found in many foods. But to get a daily dose of about 1000 IU, you will need to eat, for example, cheese, 4.5 kg, and yolks - 100 pieces. It is clear that this is unrealistic. And the use of fatty and rich foods reduces the level of absorption of vitamin D.

Vitamin D can be obtained through ultraviolet light. But in Russia there are many places where you can sunbathe all year round. What, then, to do, how to saturate the body with a vitamin necessary for vital activity?

When to take vitamin D

People should understand that a deficiency, like an excess of any vitamins, is fraught with health. Therefore, before taking them, you should seek the advice of your doctor. He will give a referral for a blood test, and then decide if vitamins are needed. If so, the doctor will adjust the dosage. So you don't need to saturate your body with any drugs on your own, you can harm yourself.

The doctor will prescribe a course of treatment if necessary. Vitamin D is drunk before meals.

What form is vitamin D in?

Today in pharmacies you can find two forms - liquid and capsules. The dosages in them are small, preventive. Most often, this prohormone is part of vitamin complexes. They should be prescribed by a doctor.

Why is the prohormone promoted

Despite the fact that the study of this vitamin began long ago, scientists from many countries are engaged in it, its effect on the human body has not yet been studied. Many luminaries from medicine generally believe that pharmacists add popularity to the drug, and people are led by their advertising. So you need to use vitamin D after analysis and on the recommendation of a doctor.

Do you often buy this prohormone at the pharmacy without contacting your doctor?
