Hey bros I gotta quick question here. just continuing my research on b12 I heard someone mention something about using b12 injectables over oral b12. Now is there a difference in the effectiveness or what? Any thoughts?

Here's some info on it. This says that there is no advantage to injecting, but other sources say there is an advantage.
Although it is popular to inject vitamin B12 in the treatment of anemia and B12 deficiency, injection is not required as the oral administration of an appropriate dosage has been shown to produce as good of results as injectable preparations in treating vitamin B12 deficiency. The most common forms are cyanocobalamin and hydroxycobalamin, however, vitamin B12 is active in only two forms - methylcobalamin and adenosylcobalamin. These later forms are active immediately upon absorption, while cyanocobalamin and hydroxycobalamin must be converted to either methylcobalamin or adenosylcobalamin by the body. Methylcobalamin is preferred over adenosylcobalamin as 90% of the body's active B12 is in this form and methycobalamin is easily converted to adenosylcobalamin.

wouldn't you have to take more of a tablet form to get the same amount as you would using injectables?
