Are 2000 Ie vitamin D too much a day?

Vitamin D should be able to prevent a number of diseases. Although the media are often warned of side effects, many, even without consulting the doctor, take vitamin D. Some common preparations start at 2000 IE a day. Is that already too much?

Is 2000 Ie too much a day?

There are many different recommendations for vitamin D, since experts are not entirely agreed. The German Society for Nutrition advises people who are little outdoors to take 20 micrograms of vitamin D a day through dietary supplements. That is the equivalent of 800 IE a day. Internationally, the recommendations are even lower:

Li): Relative List-None (&> Li): PL- (1.2EM) (&> Li): Marker: Text- (0) (&> Li): Relative (&> Li): Before: Absolute (&> Li): Before: W-3 (&> Li): Before: H-3 (&> Li): Before: BG-fire (& Li): Before: LEFT-0 (&> Li): Before: Top- (8px) (&> Li): Before: Rounded-Full My-5 « >
• German Society for Nutrition (DGE): 800 IE
• National Health Service (NHS, Great Britain): 400 IE
• National Institutes of Health (Nih, USA): 600 ie

Accordingly, 2000 Ie would be too much. However, nephrologist and metabolic expert Helena Orfanos-Boeckel do not have this experience in her practice for preventive medicine and functional medicine. It is committed to individually adapted nutrient and hormone therapy. « I don’t advocate haphazard nutritional supplements, but we have to admit that many of us have nutrient deficits. » In her practice, she has had the experience over the years that many have one Vitamin D deficiency have. Even if there is no absolute defect, according to the doctor, this does not mean that the body receives all the nutrients in sufficient quantities, as it explains to us in the interview.

« Most relatively healthy people in my practice with skin type 2-3 need 4000 to 5000 IE daily, accompanied by the Cofactors calcium, magnesium, boron and vitamin K2, to keep a 25-oh VD mirror of 60 ng/ml with a D-ratio of 0.5, » she says. The vitamin D ratio describes the ratio between two forms of vitamin D in the blood:

Li): Relative List-None (&> Li): PL- (1.2EM) (&> Li): Marker: Text- (0) (&> Li): Relative (&> Li): Before: Absolute (&> Li): Before: W-3 (&> Li): Before: H-3 (&> Li): Before: BG-fire (& Li): Before: LEFT-0 (&> Li): Before: Top- (8px) (&> Li): Before: Rounded-Full My-5 « >
• 25 (oh) D (calcidiol) = Memory shape of vitamin D
• 1,25 (OH) ₂D (calcitriol) = active form of vitamin D

According to Helena Orfanos-Boeckel, warnings Vitamin D side effects often not the actual vitamin d meant, but its active form calcitriol. In high quantities, this can overlook calcium from the bones. It is therefore not only the decisive factor for assessing safe therapy Vitamin D mirrorbut also the so-called vitamin D ratio and the calcium value in the blood. Even high calcidiol values ​​of up to 150 ng/ml, ML, which can occur in the context of curative vitamin D doses, the doctor considers it harmless-provided the calcium metabolism is stable and the D-ratio remains below 1.0. So that treatment is safe and effective, regular blood controls are essential. Her most important message is: « Measure, make, measure! » Because only those who know their blood values ​​also know their conservation dose – the amount of vitamin D that is necessary to keep optimal mirrors.

2000 ie vitamin D a day: when is it too much?

Although 2000 Ie none for most Overdose triggers in the body, a general recommendation for daily dosage of vitamin D is difficult. « Everyone has their own vitamin D shoe size. What fits for one can be too little or too much for others, » says the doctor. « It also depends on the medical context in which vitamin D therapy takes place. While some people are already optimally supplied with 1000 IE per day, others need up to 20,000 IE every day to achieve stable values. »

The European Food Safety Authority (EFSA) still has A maximum amount determined that is harmless to health when taking daily. It is 4000 IE in adults a day. According to the Society for Applied vitamin research, EFSA only rated this recommendation on a scientific basis last year and came to the conclusion that the upper tolerable recording amount did not have to be changed. Older people are recommended higher doses a day, but only under medical supervision.
