B-12 deficiency....shots and supplements?
Looking for experience with B-12 supplements.
Seems like there is such a wide variety of dosages from very small to multiple 1000's mcg.
Most descriptions from google are not very specific and tend to be on the very low side of recommendations.
In addition there is the discussion of whether supplements are effective at all. Our doctor said it can't hurt to take the supplement and could not attest to effectiveness.
