Vitamin B12 Injections
To build up your levels of B12 you will need a course of boosters to begin with. For some people this may be 3 and some may be 5. Once your levels are where they need to be you can then have a booster every few months. The injection is quick and done in the arm.
Yes you can take B12 in tablet form but the acid in the stomach and digestive system means you will only absorb 2%. The most effective way is to inject it.
