Which type of potassium is recommended? Is powder better than the capsules? Ever since starting methylation (MethylB12, MethylFolate, TMG), I have noticed huge headaches/migraines quite frequently. The first time it happened was when I took too high dose of methylfolate in the beginning (1000mg), now it happens all the time with many supplements/detox things I take. I am hoping taking potassium might help with these head pains. Along with tight shoulder/trap/upper back muscles, mild constipation, anxiety, palpitations, frequent thirst, etc.
