> Well, I think you should be more careful with your recommendations. 800-1000 mg Magnesium is going to intoxicate alot of people.
I'm going to just start again. That value was a daily flux. It assumes 200-400 mg magnesium from food and water. Hard water is a significant source of calcium and magnesium ions. Its effect on soap (nothing more than free fatty acids, in pure soap) proves the presence of calcium and magnesium ions. The rest of that 800-1000 must come from supplements, if it isn't coming from diet. That gives a daily supplement intake of 400-800 mg magnesium (the boundaries of the two ranges). I always recommend splitting the dose. I always recommend taking it with food. I always recommend starting low, and going slow. The inference that I was advocating a bolus dose on an empty stomach is incorrect. That would give an adverse reaction, as you have inferred. But it's not going to happen if you follow the rest of what I have said about magnesium supplementation.
Now, to the better graph I spoke of last night. I found it, this morning. With my awake brain.

Click on it, and it loads the full sized image, so you can read the text embedded in the chart.
RDA is curve 3. I speak to curve 5, in my recommendations. Optimal intake, absent any signs of impairments by even subclinical toxic effects, in even the most sensitive individuals.
The curves they show had to be crammed into the figure. The flat part of the "bowl" shape, in between the two sets of curves, is often incredibly wide. For zinc, though, these curves are pretty much just how it is. For selenium, there are orders of magnitude inside the "bowl".
This is my philosophy of nutrition, being in the bowl, not stuck on the low edge, where RDA is.
