Just wondering -- is it better to split up your B-12 dose during the day, or take it all at once in the morning? I just upped my dose to 5,000 mg of methyl and wasn't sure if I should cut it in half and take half in the morning on an empty stomach, and half in the afternoon two hours after lunch.

In theory, could taking some B-12 in the early afternoon give you more energy for late in the afternoon? Or does it really not matter?
