What if Vitamin D levels are abnormal?
If vitamin D levels are low, bones can become thin and brittle or abnormally shaped if still growing. In older adults, deficiency can contribute to the development of osteoporosis.
In contrast, since vitamin D can be stored in fat, toxic levels of vitamin D can happen over time with too much replacement. However, this is rare and usually requires many months of taking 100x the daily recommended amount to occur. When vitamin D levels get too high you can have too much calcium in your blood stream causing problems with nausea, vomiting, weakness, kidney stones, and bladder irritability.
