How does the new Calcium Absorption Score work?

Fern36

I just discovered the new Calcium Absorption Score. I don't understand how it works or what causes it to rise or fall. Yesterday I consumed roughly 1,200 mg of calcium (mostly from dairy and soy milk) yet this new score says I only "absorbed" 30%.

Maybe a score of 30% is the optimum, if the body can not absorb all the calcium? How would you get 100% absorption?

_"The absorption of calcium varies depending on the type of food; absorption from dairy products and fortified foods is about 30%, while absorption from certain plants may be much lower due to the presence of compounds that form indigestible salts with calcium."__
