Hi Larry,
I was found to be deficient in vitamin D and have been taking 400 mg daily for more than a month.
For two weeks now I am suffering from severe lower back pain and stiffness - a worsening of problems I used to have. Can this be related to taking vitamin D or to the fact that I don't take calcium supplemements with it?Thanks,
Nellie.

But, that will occur with or without vitamin D. You'd have had to be extremely unbalanced already for the vitamin D to have had that effect. (Again, I'm assuming you meant 400 IU.)
Provided you don't have kidney disease, your body can easily deal with excess calcium in diet, so there is no reason not to take calcium supps that might exceed your bodily requirement. I advise supplemental magnesium in roughly a 2:1 calcium/magnesium ratio, as bone is composed of both.

Hi Larry,You are right, I meant 400 IU :)
Just out of curiosity -can harm result from taking vitamin D supplements without calcium if consumption of the latter is insufficient? In other words, does taking vit D increase the reabsorption of calcium from the bones, for instance?Thanks again,
Nellie.

You're welcome.
