Maximum vitamin D3 dose - does a bump dose make sense?

As with many substances - the dose makes the poison. Vitamin D can support our skeletal system, immunity and heart, but it can also damage the kidneys or cause calcification of the arteries.

What is the maximum daily intake of vitamin D?

.

The maximum safe daily dose of vitamin D for you depends on your age, health, complexion, diet, lifestyle and official recommendations. You may not be satisfied with this answer. Believe me, if anyone gives you a specific dose without knowing you and your medical history - they will most likely mislead you.

In writing this article, I found numerous forums where users are asking about dosage, exceeding daily doses and the risks involved. 

I will present some interesting facts so that you are not left without answers.

  • Most healthy people need daily  800-4000and  IU of vitamin D.
  • In the spring and summer 15 minutes of sun exposure, between 10am and 3pm with arms and legs uncovered, will give you as much as supplementation with  2000   IU vitamin D.
  • Research shows that taking  60,000 IU of vitamin D  daily for several months can cause toxicity (harmful excess)and.

Lethal dose of vitamin D

.

There is no conclusive data on the lethal dose of vitamin D. Not surprisingly - a human experiment would be risky. However, I was able to find a very interesting description of an extreme  overdose of vitamin Dand

In a nursing home in the Netherlands, two patients (aged 90 and 95) received accidental single doses of 2 000 000 IU of vitamin D3. Yes, you can see the six zeros. This did not cause clinically apparent toxicity requiring hospitalisation. Elevated plasma calcium levels were observed for a further 2 weeks. Patients survived. 

.

Is this already proof that it is possible to take massive doses of vitamin D? No.

I have found case reports in which regular daily intake of high doses of vitamin D resulted in dangerous health effects. Patients with vitamin D toxicity come from many countries -  Germany ,  the UK   or India. In  Poland, such cases are also reportedand.

Daily vitamin D requirements

.

Do you know what your daily vitamin D requirement is? Did you know that it depends on your age, your lifestyle, your diet and even your complexion, among other things? Take a look at my article with the current recommendations for vitamin D supplementation. There you will find a concrete dose of knowledge.

Vitamin D impact dose

.

The use of a vitamin D shock dose (above 50 000 IU) is necessary in 99% of cases, especially if someone decides to do so without consulting a doctor. Such amounts have been used in scientific studies for rickets (R. Shah, 1994).

Internauts are looking for information about rapid vitamin D supplementation and a bump dose. According to official medical recommendations, in most cases this is not the best choice to treat the deficiency. Why?"

Vitamin D deficiency is treated according to strict medical guidelines. Patients work with their doctor to treat the deficiency, selecting doses and timing of supplementation. Patient education is very important. I explain the origin of the deficiency, how to prevent it, how to enrich one's diet and the importance of outdoor exercise. A single powerful dose will not fix several months of neglect.

.
Patients often want to cure a deficiency with huge doses, without understanding how vitamin D is metabolised in the body.  For many years, researchers have been looking at vitamin D and its effects on our bodies. This and like any vitamin can be overdosed, so let's supplement sensibly and according to our individual needs.

Summary

.
.

In summary:

.
  • We do not know exactly the single lethal dose of vitamin D - and very well! Let's not test it.
  • Taking one-time shock doses is not recommended in most cases.
  • .
  • If you have a known deficiency - talk to your doctor about treatment and follow the recommended doses.
  • .
  • Systematic, optimal supplementation is healthier than taking massive doses all at once or over a long period of time.
  • In addition to supplementation, to correct a deficiency, take care of yourself! Enrich your diet, make an effort to be frequently active outdoors.
