Can you overdose vitamin D?

Vitamin D is a fat-soluble vitamin. This makes sense because the body needs this vitamin permanently and the fat store serves as a buffer. In addition to a variety of positive effects of vitamin D no adverse effects are known, if there hasn't been very overdosed. 

Extreme overdose, ie blood concentrations of more than 150 ng / ml vitamin D, may cause dizziness, vomiting, muscle weakness, diarrhea and eventually long-term gastric ulcers. In the cerascreen vitamin D often choses dosage of 2 capsules per day, ie 2,000 IU (international units) Vitamin D stabilize your vitamin D level, e.g. preventive in the winter months, but do not increase it. 

It is advisable to control the vitamin D value and to have it generally determined about twice a year, since the concentration should generally decrease and be readjusted even if the maintenance dose is taken daily throughout the year.
