I've been taking 250 mcg - 500 mcg every second day of methyl B12, plus 100 - 200 mg of magnesium (amino acid chelated) and I think I've found a balance that is working for me. However, if I have too little B12, the chest tightness and arm paralysis comes back again, especially after I've gone to bed, and too little magnesium and my anxiety goes through the roof. However, I'm in a better position than a few weeks ago.

My question is, how does b12 and magnesium work together?

Did taking magnesium unlock the b12 in my body for me to use?

Are there any other essential vitamins or minerals that I should make sure to take?

thank you
