calcium recommendations

Hi all, I am wondering what recommendations for calcium would be for weight-trainers who do high volume load bearing exercise daily? Currently I take approx. 2500 mg. but I'm apprehensive of the soft tissue calcification I've heard so much about and speculate whether it would be best to reduce the amount. I have a high amount of vitamins A, K(assuming store-bought butter contains this item), and D3 in my diet currently. Magnesium I assume to be adequate(meat and eggshells). Here is my current 'supplementation regime': (with a meal containing protein and fat in all cases): 1 eggshell(lrg. chicken or duck egg) x2 perday 2 500mg. calcium carbonate tabs perday. I am thinking of eliminating the calcium carbonate altogether but would like some sound advice(folk wisdom or scientific) regarding appropriate amount and source of calcium. Also, does anyone have any links to research on 'calcification of soft tissues' that spells out in an accessible way the issues, causes and solutions? At the very least I will stick with the eggshells...

Sorry to say I'm too much of a neophyte re: nutritional research to have stumbled upon anything re: eggshell nutritional composition but: Why is there always mag+cal together in natural substances(boones, eggshells) if they negate one another? From what I've hearing on Paleohacks magnesium appears to be the main focus and calcium is put in the dog house. Why? What, generally, is the relationship between cal & mag and what practical recommendations would you give for diet inclusion? Surely the eggshells are good(and cheap and plentiful)?

Do you have any data on the amount of magnesium in eggshells? I'm always after sources and was under the impression that shells were mostly calcium (which would be a very bad thing, since calcium reduces magnesium absorption).

Good advice, I'll jettison the calcium tabs. Would eggshells/ground bone be a good option given the phosphorous content(their having mag and all...)?

Again context.....for most I don't recommend calcium supplementation. A guy like you you don't need it. Magnesium maybe a different ballgame.
