How long does it take to build up calcium in your blood from supplements?

Hi guys,

My doctor wants to check my blood calcium level as I have osteoporosis. I've not taken any supplements for a couple days as I ran out and won't be getting more for another week when my next ones come in the mail. I don't want to test now since I haven't been taking any.

Would it take a couple weeks of supplementation to get a good result or longer?

I want to get a good result as if I don't she may put me on Fosamax or something similar which I don't want to do.

Thanks. Tweet
