>I have osteopenia from calcium deficiency, and believe me I'd prefer magnesium deficiency. Calcium also helps with anxiety and sleep. And as a lifelong depressive, I'm walking proof that depression is not caused by too much calcium.
There are two simultaneous and opposing processes occurring in bone tissue, mineral deposition by osteoblasts, and mineral dissolution by osteoclasts. If you're magnesium deficient, you're going to get an increase in osteoclast activity, as the biggest and most accessible store of magnesium in the body is bone. This leads to osteopenia and osteoporosis, even in the presence of adequate dietary calcium. This is identifiable by high blood calcium levels despite evidence of bone porosity. Unfortunately, the high blood calcium levels shut down the active uptake of both calcium and magnesium, exacerbating the magnesium deficiency. One of the leading causes of magnesium deficiency is.....magnesium deficiency.
I'm not suggesting you're wrong, or anything like that. It's just that bone calcium loss has to be assessed in the context of a number of other parameters. Dietary calcium intake is just one variable to consider.
