Just got back my labs. Despite increasing doses of Mag Citrate (200/day to 800 a day) and despite increasing doses of Cal Citrate (1800 to 2400 a day) my PTH went up from 74 to 77 and my Magnesium dropped from 2.1 to 2.0 to 1.9. Not alarming, I know, but not what I expected. I've read completely contradictory things on whether to take Magnesium and Calcium together or apart. I've been taking them together. Does anyone have any experience to share on this? Also, what about Magnesium Gylcanate? Is that better absorbed in us than the citrate?
