PS.
Getting a blood test will only tell you how much B-12 is in your blood-stream that day.
Not your liver, where it is processed and stored for use inside the body. Your liver can hold quite a bit for future use.
Thus, if you just got a injection of B-12 and were tested - a high reading would show. This says nothing of how much of that B-12 your body will process and keep.
Red meat is a great source of B-12, there are lots of others things too.
Food my friends, not shots, those docs are making a buck off your ignorance.
