About a year ago my internist seeing some of the interim reports said to get off calcium supplements; calcium from diet only. Because I have osteopenia she also wanted me to see a rheumatologist to measure the bone-turnover rates. So I ended up being his (annual) patient also. He wasn't pleased that I'd gone off the calcium. Should have taken notes but the jist of what he said was that the recalculation of some of the early data (possibly more than one study at issue here) suggested that moderate calcium would be fine. But now this ... ?
Haven't been too diligent about organizing the relatively quick reading I've done and can't provide links. But there's also a school of thought that vitamin K2 is essential for the calcium to be absorbed into the bone and not end up clogging arteries.
The rheumatologist (though this was before this last spate of news articles that may or may not reflect new analysis
) recommended no more than 500 mg of calcium daily with 1000 mg thru diet. I've gone back to taking the 500 mg. at night - but this time with K2.
My gynecologist *also* wanted to weigh in (after seeing my latest DEXA scan) but never did make an appointment with her. Juggling potentially 3 different opinions was a bit too much ...
