Just yesterday I went to see my doctor to ask her to give me Vitamin B12 shots, and I used being vegan as a excuse to need them. Before giving me a lecture on how all vegans are deficient in iron/protein/calcium, she told me that I wouldn't need them at my age (15/16) and that I should just take a Vitamin supplement. She's a very knowledgeable doctor, but only knowledgeable on the things that she was taught in med school. She insisted that I was deficient in iron when CRON-O-meter clearly says that I'm not deficient in anything except vitamins B12 and D.
So now that my doctor won't give me the shots, what can I do to increase my B12 levels? I've heard of this supplement (i forgot the name) that can be taken under the tongue but what is it and where can I find it?
