I recently was experiencing big drops in my blood pressure. My baseline blood pressure is low about 90/60 — I was taking about 500mg of magnesium as part of a calcium/magnesium supplement. I was also taking an additional 150 - 250 mg of magnesium. I noticed on days when the magnesium dose was higher, my blood pressure would plumit - I got readings in the 80’s over 40’s once I recovered enough to operate the blood pressure monitor (I got extremely light headed and weak, and then my heart would start to race). My doctor didn’t think much of my magnesium theory. However, all the heart tests he did showed that I am perfectly healthy 43 year old female; and he couldn’t account for the drop. Is it possible the magnesium was causing my blood pressure to drop? and since my base line is already relatively low, a little bit lower can cause a big difference?? please let me know your thoughts - it’s scary to feel like everything is draining out of you and not know why. In the meantime, I’m not taking magnesium, but need the cal/mag for my bones and don’t know how to resolve this.
