For those of you with no colon (or if you know the answer), what are the most soluble forms of magnesium and vitamin B one can take? I need them for helping prevent migraines. My neuro team has switched me over to mostly infusions/injections for preventing migraines because they don't think I'm absorbing the oral meds well. But these are 2 I need to be taking on a daily basis. Thanks!
(Please no suggestions on different migraine meds- I have tried a completely holistic route in the past and now am being treated with the latest therapies available in the US. If you've heard of it there is a 99.9999% chance I've tried it in the past)
