I've been supplementing with magnesium for years but was nevertheless recently diagnosed with diabetes. [sigh]
I've experimented with quite a few forms of magnesium, which I started taking primarily for depression after I discovered this website
http://george-eby-research.com/html...on-anxiety.html. I like to give him credit as I feel he may have saved my life.
I've tried various forms of mg through the years; favorites are mg taurate, mg glycinate/lysinate, mg malate and mg orotate.
In my experimenting I've found that if I'm not eating dairy, which I didn't do for a while, it is indeed possible to take too much magnesium, even at modest doses of 300-600 mg. Food cramps and general weirdness were my clues, relieved by some calcium. Maybe it's just me. I feel like I'm always working out that calcium/magnesium ratio. My understanding is that magnesium and calcium are antagonistic and synergistic so that too much or too little may render the other ineffective. Before I was supplementing with mg, my theory is that I was getting way too much calcium and probably utilizing very little of the mg in my diet. Calcium can be an excitotoxin to the brain which is what I believe was happening when I was so depressed I could barely function. If I had listened to my psychiatrist, btw, I wouldn't have tried magnesium as he said it would be useless.
Anyway, thinking myself a pretty practised experimenter, probably averaging about 500 mg a day, but much more some years and a bit less at times, I was really thrown for a loop last year when suddenly magnesium seemed to be acting differently in my body. I was taking the recommended dose of Vit D for my weight, I thought, and assuming I was probably low to begin with (too poor/cheap to order a self test) which was anywhere from 5,000 IU to 10,000 IU/day. No danger of toxicity, right?
But I began having heart palpitations daily, bad enough to keep me awake at night. And my usual magnesium doses were making them
worse, and giving me leg cramps besides. It was
really messing with my head because I feel I need magnesium to stay sane. I still took 125 to 250 mg a day of mg taurate, my absolute minimum, but had to cut back on any additional. Subsequently I realized, after I quit taking so much Vit D that they went away. Vit D promotes calcium absorption I've learned so that's probably the connection but I still don't get what was going on there.
Right now I'm taking 600 mg of magnesium glycinate/lysinate and think I may experiment with a more after reading this thread. I'm getting 1,000 IU of Vit D in my daily multiple and take another 2,500 IU about once a week. I'm afraid to take more because of the heart palpitations and another issue as well.
I found out my blood sugar was high when I went to the doc for post menopausal bleeding. I have a mass in my uterus and see the oncologist next week. Vit D has always felt to me like it definitely increases some sex related hormone, most likely estrogen I'm assuming, as I can feel a direct hit to my libido when I take it (intermittently, not continually!
). Anybody else ever notice this? I have additional bleeding when I take more Vit D and in fact, the initial onset of this symptom, worse back then, was when I was taking all that Vit D. (Both uterine cancer and polyps are affected by estrogen I now know.)
I'm curious what other experiences people may have had with the calcium/magnesium ratio being impacted by Vit D as well as any other hormonal observations.
