I answered the question on osteoporosis that was posted recently and realised I'm not sure if I'm taking the right combo of vitamins, given I have osteoporosis myself. K2 and D3 are fine, I take those, but I also take 600 or 800mg of magnesium citrate (I partly use this to prevent constipation, which I suffer from mildly) but I don't supplement calcium although I eat cheese a couple of times a week, loads of greens (though not sure if calcium is very bioavailable in those) sardines with bones a couple of times a week, loads of bone broth (has that got calcium?)
I was reading an old question on magnesium and calcium RDAs and there was mention of a 2:1 ratio of calcium to magnesium which would mean I need 1,600 mg of calcium - no way do I get this. So should I cut back on magnesium (in which case other constipation remedies welcome!) or add more calcium or even supplement with calcium which I really don't want to do having read so many horror stories. Or am I ok with what I'm on? Anyone know any more about this?
