High blood calcium: Excessive vitamin d supplements (>10, 000 units daily) can cause excessive calcium in the urine leading to kidney stones and high blood calcium. This could result in kidney failure.

No, but: You should ask your doctor to measure your vitamin d level. If it's low, you will need supplemental vit. D to raise it, and most likely to maintain the correct level.

Yes, if deficient: Vit d deficiency is very common, the best explanation I have is that it is broken down by cadmium a pollutant that has become more prevalent since lead was taken out of gasoline in 1980. Cadmium causes stress and inflammation. If vit d deficiency is present just taking vit d will not be enough. Menstruating women need iron . Zinc and magnesium are necessary and a healthy life style.

Up to 50000 U/wk: The dose of vitamin d depends on how low the level. A mild decrease could be treated with 2-3000 units daily. A severe decrease may require 50000 units once or twic a week for several months. A blood test will be needed to determine if the deficiency has been corrected. Then a daily dose of 1-2000 units may be adequate to keep a normal level.
