i am not sure with the magnesium. i take way too less to make any difference. when i take it its like 100-300mg per week.
I got a very intractable severe Mg deficiency, probably by correcting my 25(OH)D to ~70ng/ml, thereby correcting my below normal serum calcium over the course of two years. Though I took at least ten times as much magnesium as you. 14-12 years ago.Vitamin D gives me weak exhausted muscles a few days later. like next day, plato'ing 2-3 days after, then regulating itself back to normal. somebody has a idea what that can be?
i usually only got crampy muscles from vitamin D. but this seams to be a new side effect since a few month.
Fast forward, no amount of supplemental elemental magnesium (up to 2.8g, 1.8g in average for 14 years) ceased my very pain-ful muscle cramps, except above 30 Mg-sulfate IVs, upto three years ago. With covid-mania no IVs posssible anymore, the cramps nevertheless remained much more infrequent and much more endurable now.
