I have been taking high doses of Magnesium Glycinate for a couple of years now-between 800-1200mg per day for various things like headaches, PVCs, and sleep issues. I also take Vitamin D and have optimal levels of that.
I do not take any calcium but seem to get plenty in my diet. I recently had my intracellular electrolytes checked and it showed that my calcium levels were normal but my magnesium levels were low. This seems odd considering how much I take. Any ideas about why I am still deficient and would it be safe to increase my dosage by another 100-200mg?
Or should I try another form, like Magnesium Oil?
