Is injected vitamin B12 more effective than the pills?


Actually yes, but that doesn't mean a good multivitamin and mineral formula can't get you what you need. Shots are only recommended by a physician based on a deficiency caused by diet and/or mal-absorption. Vitamin B12 is unique in that it requires a carrier, called intrinsic factor [IF] (produced in the stomach), to allow its absorption throughout the intestines. As we age, the production of IF tends to decrease thus a possible need for injections, since injections go straight into the body, by-passing the need for absorption. Thus injections when/if necessary can achieve proper levels of B12 levels.

B12 injections can be more effective than the pills in certain patients who have trouble absorbing vitamin B12. In the majority of patients the pills are just as good as the injections.
