Re: does b-12 make you gain weight
If your hands and face are puffy, then you should probably stop taking it. As far as gaining weight, I think b12 increases appetite. That's what I noticed. I was HUNGRY. So maybe you are eating more cause you are hungrier. I was getting larger doses of b-12 through a b-complex not b12 alone. When I took b12 alone for one day, it was way too strong for me and I was so anxious, but when I took it as part of a b-complex the anxiety wasn't as bad, but I still got hungry. I didn't gain weight though. If anything, I lost weight. Maybe you should try a b-complex with a lot of b-12 in it.
