Vitamin-D-Päparate more of a risk than useful
Vitamin D is responsible for many important functions for health, which is why many people resort to supplements and Vitamin D supplements. However, the Federal Institute for risk assessment (BfR) comes in a recent Report to the conclusion that taking Vitamin D supplements with doses of 50 µg or 100 µg from a nutritional point of view, is not necessary.
Vitamin D is produced by the body when our skin’s contact with sun light. On the diet, only a relatively small proportion of Vitamin D on the other hand, supply of blankets. And while the body’s own Vitamin d production-no Overdose is possible, consists in taking high-dose Vitamin D, for example, on certain dietary Supplement is quite a risk.
Risk of Overdose checked
Therefore, the BfR products rated with a dosage of 50 and 100 micrograms (µg) Cholecalciferol (a precursor of the active Vitamin D) health – as a representative for highly concentrated preparations that can be taken by consumers in order to increase their Vitamin D intake. The risk of Overdose, have been checked.
Symptoms of Vitamin D Overdose
In the case of a Vitamin D Overdose elevated calcium values in the blood serum (hypercalcemia) and clinical symptoms such as fatigue, muscle weakness, vomiting, constipation, and cardiac arrhythmias the possible consequences. “A prolonged hypercalcemia can stones in kidney, kidney calcification and, ultimately, lead to a decrease of renal function,” warns the BfR.
Risk for the occasional consumption of low –
In terms of overdose risk, the BfR comes to the conclusion that in the case of only an occasional consumption of such high-dose preparations of health are currently considered to be unlikely. “But in the long term and daily high-dose Vitamin D supplements, and interprets the current study situation on an increased health risk”, according to the BfR.
Additional feed is not usually required
However, the Federal Institute does not see the Benefits in the Vitamin D preparations. Because even without the sun light irradiation, a daily intake of sufficient quantity of 20 µg of Vitamin D to meet the body’s need for most people. If there is sufficient Outdoor exercise, and appropriate sun exposure on the skin, as well as a balanced diet, a good Vitamin D supply can be achieved even without the intake of Vitamin D preparations.
Taking check medical
In the case of a very small part of the population of the Vitamin, according to the BfR-D-is not necessary, however, to cover in a natural way, and for these people, an additional supply can be quite useful. However, such persons from high-risk groups, for which it is to take a relatively more serious, requiring treatment for conditions of should come under the care or lack of Vitamin D, the intake of the preparations before medical check, the note of the BfR.
The Federal Institute comes to the conclusion that “in the context of a growing market of Vitamin-D-fortified foods, high-dose Vitamin D supplements have the Potential to cause a health risk, the total intake of Vitamin D.” Health benefits, however, for a majority of the population do not recognize.
