Overdose on Vitamin D


Overdose on Vitamin D. Vitamin D overdose symptoms. Can you have too much Vitamin D in the first place?

Overdose Vitamin D

It is very difficult to overdose on Vitamins D. Health experts suggest that overdose would mean enormous doses of almost 20,000 IU a day. At these levels, there can be damage to the kidneys, bones and the cardiovascular system.

Excess Vitamin D is stored in the body and can accumulate over time. However, the release of Vitamin D into the body system is carefully regulated, so optimum Vitamin D levels can be maintained.

Since most people consume about 1000 IU a day, it is difficult to reach overdose levels, unless you have been taking multiple pills and injections. Regular food diets will rarely result in a Vitamin D overdose. To be safe, you should check with your physician again if he recommends a daily dose higher than the recommended 1000 IU a day. A much more likely problem is a deficiency of Vitamin D.
