Alright, I'm confused about all of this. I don't eat much dairy products and that's a problem because dairy products are high in Vitamin B12 (and Calcium of course). So I went out to buy some Vitamin B12 to make up for it. I was planning on just taking about 20-30% of my daily needs through a pill and the rest through chicken. I had two options to buy from... 100 mcg and 1000 mcg tablets. I took the 100's because I thought that'd be closer to the 20-30% target that I want. I get home and search online how much is recommended per day based on a 2000 calorie diet. It says 2-3 mcg a day! I have 100 mcg tablets! Surely something must be wrong because who in their right mind would take this much... not to mention 1000 mcg tablets! Am I missing something?
