Every person in the world dreams of good health and a long life. Vitamins, minerals and other nutrients are necessary for the proper functioning of all systems and organs of the body. Most of them we get every day with food, but sometimes this is not enough. In this case, most of us decide to take additional vitamin complexes to increase our defenses and prevent diseases.
Any drugs should be prescribed by a doctor, taking into account the needs of a particular person. And vitamins are no exception, since their uncontrolled use can be dangerous. The Healthline edition told what vitamins are and what an overdose of them can threaten.
The modern pharmacological industry offers free access to many vitamin complexes for all occasions. However, ignorance of their composition or list of possible side effects can have negative consequences.
What are vitamins?
All known vitamins are divided into two types: water soluble and fat soluble.
The first type includes vitamin C and B vitamins (B1, B2, B3, B5, B6, B7, B9, B12). They do not accumulate in the tissues of the body and are easily excreted in the urine, so if overdosed, they have a lower risk of causing serious complications.
At the same time, taking large doses can have potential side effects. So, scientists argue that an overdose of vitamin B6 over time can lead to irreversible nerve damage.
The second type includes vitamins A, D, E and K.
Unlike water-soluble vitamins, fat-soluble vitamins accumulate in body tissues and do not dissolve in water, and their excess can be toxic.
Some research suggests that taking too many vitamins A, D, or E can have negative health effects.
What is fraught with an excess of vitamins?
It should be noted that natural enrichment with vitamins from the diet cannot lead to serious negative consequences. In the same time concentrated supplements may have side effects.especially for people with health problems.
So, scientists say that an overdose of vitamin C can cause gastrointestinal disorders, including diarrhea, convulsions, nausea and vomiting, and also provoke migraines.
High doses of niacin (vitamin B3) can raise blood pressure, impair vision, and damage the liver, while excess vitamin B6 can cause severe neurological symptoms, skin lesions, nausea, and heartburn.
Fat-soluble vitamins can have an even greater negative impact if taken incorrectly for a long time.
Thus, experts note that hypervitaminosis A can cause nausea, increased intracranial pressure, coma, or even death.
Toxicity from taking too much vitamin D, scientists say, can lead to irregular heartbeat, loss of appetite and weight, and high blood calcium levels, which in turn can damage other organs.
Studies of vitamin E intake have shown that a large amount of it in the body can disrupt blood clotting and lead to bleeding or hemorrhagic stroke.
As you can see, violations in the body with improper intake of vitamins can be quite serious, and prolonged excessive use can lead to the accumulation of toxic substances in the body and even death.
The best and safest way to get nutrients is a balanced diet, but sometimes there is a special need for vitamin complexes. Elderly people or those who have serious illnesses need enhanced support for the work of the body.
If necessary, you should consult a doctor for prescribing vitamins. After a comprehensive examination, the specialist will be able to assess the needs of the body and prescribe the correct dose, which will be not only safe, but also useful.
Without a complex of vitamins, the coordinated work of the systems of the human body is impossible, but you need to treat their intake sensibly and carefully. Any medicine can both help and harm. To take vitamins only benefit, follow the qualified advice of specialists and do not self-medicate.
Earlier, GLOBAL HAPPENINGS talked about ways to increase immunity. Doctors stressed that zinc and vitamins C, B and D are especially important in winter to prevent diseases.
