One of the weird things that happens when you go vegan is that you often find yourself having conversations about bodily functions. So, it wasn’t too strange that my vegan friend and I started talking about how our B12 supplements make us have to pee constantly. My friend was also having a crazy appetite from her new pills. This is also a pretty normal side effect, but it usually normalizes after a few weeks. Her appetite was still going strong, so I asked her what B12 dosage she was taking. She didn’t know. I asked her what type of B12 she was taking. Again, she didn’t know.
