An article I stumbled on regarding calcium absorbtion

I found this article on calcium absorbtion today and thought I would share.

Just when I thought I had this calcium thing sorted out ...here comes more science :P  Thank a lot ..great article

This is for normal people without their guts rearranged like us.

OOPS this is the page I meant to copy/paste, but it is from the same article.

Ok, that's better.  I take 2,000 mgs of calcium citrate a day.  I buy the Kirkland brand from Costco.  If you have trouble swallowing these they disolve fairly quickly in water and then down the hatch.  I set a timer on my cell phone to remind me to take them every two hours and then I take my iron a vit C at night. Not a problem.

Well I have been taking the liquid Calc. Citrate from Wellesse w/Vit D3 while waiting on the arrival of my chewable Bariatric Adv.  That arrived today and after reading this article I find that both say: Caclum (from  Calcium Citrate USP) or Calcium (as Calcium Citrate and Tricalcium Phosphate).  I went on the Wellesse website the other day and found that it has 80% Calc Cit and 20% Tri Phos.  and just figured I would take a little extra to make up the difference.

So now i am confused why Bariatric Advantage would provide this in this form if we cannot absorb it fully in that form. 

thanks for sharing that I was unaware of Zinc interacting with Calcium.
