Vitamin D is good for the bones, the muscles and also strengthens the immune system. So there can’t be “too much” of it, right? – Unfortunately, no. Because although vitamin D is health-promoting in many ways, taking too much vitamin D can lead to an overdose – also known as “poisoning”. And she can in In extreme cases even life-threatening will.
which Causes such a vitamin overdose has, with which Symptoms Those affected have to calculate and what is the maximum dose should be, you can find out here.
Vitamin D overdose: Dietary supplements as the cause
Vitamin D is considered sun vitamin – and not without reason: everyone forms it when they are exposed to the sun’s rays. But this, the natural way, cannot lead to an overdose. Because the body has a kind of protective mechanism that kicks in as soon as there is enough vitamin D in the body. And also about the diet – for example, frequent eating of fatty sea fish – such a consequence is excluded.
Die Cause of too much vitamin D lies alone in the dietary supplements, through which vitamin D can also be absorbed. That Federal Institute for Risk Assessment (BfR) even warns of the health risks that can be associated with taking vitamin D supplements on your own. “Higher doses should only be taken under medical supervision and taking into account the individual vitamin D status”, according to a recent statement by the institute. Anyone who wants to take vitamin D on their own should only use preparations with a daily dose of up to 20 micrograms (800 international units). “With this amount, health impairments are not to be expected.”
With a – not medically justified – regular daily Vitamin D intake above high-dose drugs increases dem BfR according to that risk of damage to health such as the formation of kidney stones or kidney calcification. There are also cases of acute kidney failure as a result of uncontrolled self-administration of vitamin D preparations. On top of that, many vitamin D supplements ineffective and even harmful are.
Symptoms of a vitamin D overdose
To the recorded Vitamin D The body needs to be able to process and store it calcium. If the vitamin D level is increased, more calcium is absorbed from food and dissolved from the bones. A majority of the complaints of a vitamin D overdose are due to these increased blood calcium levels due (hyper-calcemia). Those are them Symptoms of vitamin D overdose:
- nausea and vomiting
- loss of appetite
- extreme thirst (polydipsia)
- increased urination (polyuria)
- feeling weak
- Kidney stones and kidney damage up to kidney failure
- Stomach cramps
Looking at the symptoms will be between a acute and one chronic vitamin D overdose distinguished. Serious consequences such as kidney failure or kidney damage only occur after a longer period of increased intake. One speaks of an acute overdose when too much vitamin D is taken once. In order to determine an overdose, the blood level controlled. If you are unsure whether you have consumed too much vitamin D, you should check your family doctor put in touch.
In the course of Corona-Pandemics Recommendations for taking Vitamin D preparations on the Internet. It can protect against infection or at least against a severe course, it said. That BfR warns against preventive intake of vitamin D for this purpose. at Covid-19 the data situation is currently still uncertain. In particular, it has not yet been possible to show that people who are well supplied with vitamin D benefit from an additional dose of vitamin D. “A general recommendation for taking vitamin D supplements to prevent a Sars-CoV-2-Infektion or a severe course of a Covid-19 disease cannot be justified at the moment,” the institute said.
Vitamin D deficiency: For whom an additional intake makes sense
Although vitamin D is not a “real” vitamin because it can only be ingested to a limited extent through food, it still plays an important role in the body. For example, a vitamin D deficiency can cause the bones to soften and decalcify. Muscle weakness, bone pain and a reduction in physical strength can be the result. People who do not produce enough vitamin D can also develop osteoporosis. Bone mass is broken down – the bones become brittle. Older people are particularly affected by this disease.
That’s why I recommend it BfR a general vitamin D intake of up to 20 micrograms per day for nursing home residents and –residents.
“Because vitamin D is formed in the skin under the influence of sunlight. However, many older people hardly move outdoors.” In addition, vitamin D formation decreases significantly with age. In the worst case, too much vitamin D deficiency can be fatal.
