Let me ask you guys something....I don't have much of an appetite and I know I am anemic and low in iron but once I get Vit B12 shot, my appetite increases tremendously. I have more energy but I end up eating more too. Does this happen to anyone here? Please let me know. Thnks!

I used to take a B12 once a month and I didn't notice any type of apetite change or energy boost when I received my injection. I have heard of some people having this kind of reaction but I personally didn't. I think it just depends on the person. It makes sense with an energy boost, apetite changes would occur since it's feasable a metabolic change could occur as well. Perhaps you sould consider a sublingual to prevent a sudden dose of B12 and a metabolic change? I use Vita4Life sublinguals, and since finding them I haven't required the shots at all. The link is here. Good luck! http://vita4life.net/products/bariatric-vitamins-b-12-sublingual.html

I also take them under my tongue. I get them at Trader Joe's. The label says the ingredient is cyanocobalamin. This isn't the same as mentioned by @@James Marusek. I've been taking them every other day and my labs came back that the levels are 1400% higher than they need to be, so I'm taking them less often.
