Great post, very useful details, thank you for that.
I've been taking Magnesium Citrate for a week or two (NOW brand, I was glad to see them mentioned as a trusted company, Source Naturals too as most of my other supplements come from them, plus one from Jarrow), I'm feeling a lot better generally, I think it definitely helped with some recent sleep trouble, even though it's not the form most suited for that purpose apparently. I might have to try some of the other forms to see which works best.
The effect-specific breakdown was very helpful, especially because I had been considering ZMA (which uses magnesium aspartate), I'm glad I settled on individual zinc and magnesium supps, even if citrate might not be optimal for me, it seems that it's definitely better than aspartate.
Do you know which (if any) form of magnesium can help with hormones, testosterone boosting specifically? Is there a specific form that interacts well with zinc? Typically it seems that people would recommend aspartate for that.
I've been taking optizinc/monomethione, I typically take it hours away from the magnesium if possible, I had read that they actually absorb better when taken separately, even though they work together. Also, how much cross-over would you say there is between different the different forms of magnesium with respect to this? Will the citrate form do anything for this?
