It seems well established that when one is taking in proper amounts of the nutrients involved with improving calcium metabolism (e.g. Vitamin D, K2, Magnesium, etc.) calcium need is reduced.
Assuming an adult is receiving appropriate intakes of such nutrients, what would be a recommended range of calcium intake to shoot for?
Edit: This question has stagnated for a while so I'm throwing on a bounty. Questions about calcium intake in the past like this one and this one have answers suggesting things like "forget about the RDA (of calcium)" and "the Paleo recommendation for calcium is too low", which seem to contradict each other (maybe) and don't give numbers regarding how much calcium we should get on a good paleo diet. I'm hoping for a range (e.g. 1000-1200mg), but feel free to speculate.
