Great finding about influencing hrv. I'll add to my queue of experiments, I have found hrv quite challenging to influence positively for more than 5 minutes.
The graphic you present on the properties is very nice, but it says that Mg is the 4th most abundant cation, not 2nd. The ones that are more abundant are
Calcium = 1100 g
Potassium = 225 g
Sodium = 90 g
From The Elements of Murder: A History of Poison, John Emsley, 2005.
Most of the weight in your bones is oxygen, not calcium, so that is why the calcium amount is as low as it is.
hmm, I looked into this more closely and I think the original diagram is correct: Mg is the 4th most abundant cation in the body as a whole. Sometimes people refer to intercellular Mg, where indeed it is the 2nd most abundant; and I concede that arguably inside the cell is what really matters.
I was aware of this intracellular/intercellular nuance originally and will concede I was too lazy to consult my psychopharmacology text to refresh my understanding of the subject. I tend to think of those four cations plus the chloride anion primarily as functioning through ion channels, and if an ion can't get into a cell, it really doesn't have much value, but that is probably an oversimplification.

Supposedly about half of the population doesn't get enough Magnesium through their diet. Perhaps you're in the other half...
Wondering if you saw anything in the research re: magnesium and headaches/migraines?

Oh dear oops! I’ll fix it when I’m back online
