Magnesium threonate or glycinate ?

Magnesium oxide 400mg, vitamin B2 400mg, CoQ10 300mg. Seems standard.

Makes perfect sense to me. Sure to be that the best one is also the most difficult to take. MAVers always seem to draw the short straw. Seems to be the way the cookie crumbles as they say. I f you are tolerating 400mg you are doing far better than I ever did. I opted for the Glycinate because that’s the one recommended best for hot flushes and from the day I hit 400mg I experienced some of the worst objective vertigo I’ve ever had so, based on the thinking an urgent need for the bathroom doesn’t combine well with the inability to walk yet alone hurry, it was bye, bye Magnesium for me. Sometimes it seems we just can’t win. I’ve read of people who controlled their VM with ‘just’ the Magnesium and a migraine diet. I never expected that it to benefit me that much neither did I expect such an adverse reaction either but I guess that’s the way it goes.Has anyone actually felt worse when starting Magnesium?
