Just in ballpark terms, I'd say a typical fairly robust human specimen has around a kilogram of magnesium, in their body. Somebody has done the elemental analysis, I'm sure....I'm just pulling a number out of thin air, off the top of my head......but it's a significant amount of magnesium, whatever the true value is. A lot more than sodium chloride, for sure. Yet we know sodium deficiency will kill you.
Your body relies on a constant redissolution of bone crystals, which is balanced by redeposition of bone crystals. There are two competing cell lines, the osteoclasts and the osteoblasts, working to undo each other's work. One lays bone down, the other takes it away.
The purpose, I believe, is to provide ready calcium and magnesium. We all know about calcium channels, and how cells fire. No doubt, calcium is important. But in all the rush to trumpet calcium, magnesium has been totally overlooked. The experts know that, too. Government funded studies, the NHANES reports. Fully analyzed. Americans are grossly magnesium deficient. The whole population is. Not enough intake to balance stress in our lives. The rat race requires magnesium replenishment.
The "powers that be" define nutrient intake with reference to overt deficiency. They do not recommend on the basis of optimal intake. They don't even try to do that. And somehow, that has become translated into some magic nutritious intake level. It ain't so, and never was.
I think the minimal sustainable intake for magnesium ions ought to be up around 800-1000 mg/day. If you do have a kilogram of the stuff, that's only 0.1% allocated to the daily flux. The daily in and out. In and out of the gut. In and out of the blood. In and out of the urine.
They're slowly catching on. Here's a good article, below, full text. In the heading is a search function. I don't know why, but you have to pay to read recent articles, pretty much, on this site. But there's a lot of free ones. A lot of full text, well written articles.
Check the correlation between magnesium intake and high blood pressure. It's in one of the papers you can pull up, for free, using the search function. Check the correlation between magnesium and mitral valve problems. Magnesium and asthma/hayfever.

The RDA numbers are woefully inadequate for optimal health.
