Personally, I found (18 months back) that magnesium malate (probably), which I'd been taking for many years, started causing me new joint discomfort and elbow locking up...
(1) Magnesium malate (1000mg) - doubling up, from only at bedtime, to breakfast too, in place of (a slightly greater higher dose) magnesium citrate tablet. I made the change because I was wondering if I was taking too much magnesium, relative to other things. E.g. calcium, I don't supplement extra potassium at all as it just seems to make me more fatigued. Seems weird that changing the form of magnesium could cause this. But it was my top suspect from the close timing. Can different citric acid cycle substrate concentrations modulate immune activity or anything particular?
... Which resolved after reducing it back to one tablet/day.
But then I had to remove malate entirely, 9 months back, for magnesium orotate now (a different CCA intermediate). Because I started getting signs of early CCI-like symptoms (neck clenching/aches, upright discomfort, moments of light dizziness and minor numbness). Which I would really love to understand.
Then, from a few months after switching magnesium type, I've been getting some new (mostly deep) internal sensations, mostly in my legs, when at rest. Like turbulent liquid flow, not pulsing, maybe tingling. Probably the thin end of "internal vibrations", like maybe e.g.
1,
2,
3. I'm thinking because I've greatly reduced my overall magnesium intake (and been trying pulsing a B-vit multi).
Anyway, I'm aiming to make a post about my current struggle with balancing these (and other) electrolyte supp's verses these new and old symptoms (of various categories). But I'm never sure which forum section is best to solicit advice..?
