Hi!
For dietary B12 deficiency (eg. in vegans), you can take oral cyanocobalamin at a dose of 50-150mcg daily in one to three divided doses. Some people take higher doses.
In malabsorption, the dose of oral cyanocobalamin is much higher eg. 1000-2000mcg daily.
RE injections. B12 can be given as cyanocobalamin or hydroxocobalamin. AFAIK, cyanocobalamin is mainly used in the US, hydroxocobalamin is popular in the UK. In fact, I'm not even sure whether hydroxocobalamin is available in the US. Hydroxocobalamin is very convenient because it only needs to be given once every 2-3 months.
