My question is what the proper amount of calcium is for someone who weight trains and walks for 1 hour daily. I had become privy to information linking calcium intake in excess and cell death. Currently I am taking up to approx. 3 grams of calcium daily in the form of 2 egg shells(~800mg/shell), 2 500 mg. calcium carbonate tablets all posterior to meals(4 times daily). Does this amount qualify as 'overload'? I am also concerned about the calcification of soft tissues that I have heard of from this site. Would anyone care to comment. P.S: I am consuming vitamin C, magnesium and occasional collagen as well as fat soluable vitamins through diet and supplements so I assume calcium absorption is adequate. P.P.S Minimal to no carbs, no grains or pulses.
I'm not an expert or anything but i'd guess you're bit overboard on the Calcium dosage.
Don't forget that, for calcium to be absorbed, you also need Vitamin D.
Vitamin K also plays an important role in directing calcium to the right spots.
I'd stick to less than 1000mg per a day. In addition, calcium tablets have a lovely tendency to cause heart problems http://www.sciencedaily.com/releases/2011/04/110419205720.htm (new research released as of a few days ago).
