So, in my case, I have no colon, and I find high doses of vitamin b12 might give me diarrhea, as I really need to absorb it. I can't remember, as I tried this a long time ago, but has anyone thought about taking a balanced b complex or b12 from the megafood vitamins as they are food? Would that bother my stomach, or I am concerned about the yeast? I tried to find posts about this, but I couldn't find much.
