Hi Yall, I have been taking high doses of mB12 for almost two weeks, and I have had diarrhea every morning of those two weeks. At this point taking either methylcobalamin or adenosylcobalamin triggers gut motility almost instantly (rumbling, a downbearing sensation). A few more details: I have actually been doing something like Freddd's protocol. Over maybe two weeks I ramped up to taking 30 mg methylcobalamin 6 mg adenosylcobalamin 30 mg methylfolate 1-2 g ALCAR something like 2000 mg more potassium than I might otherwise eat. (supplements plus many bananas) WiseGeek seems to think that diarrhea is one of the most common side effects of high amounts of mB12. So I figure I'm not the only one out there with this issue. Has anyone figured out why this might be, and what can be done to help?
