I think you should be tested for Vit D levels. Low D leads to poor calcium absorption. That is the easiest way to start.
Many of the posters here on these boards are testing for this and coming up very low.
Here is a medical video to get you started:

There is also a video on that thread from Australia which is also becoming aggressive in treating low serum levels.
We have several Vit D threads on our Vitamin forum, mostly on the first 3 pages.
I'd do this first before any other intervention, since it is likely you could be very low and that is why you are not absorbing calcium.
