I used to take B-12 shots and would leave the doctor's office feeling like a champion! The only real problem was how time consuming it was going to the clinic and having to wait for someone to give me the injections.

I went every other day for several months but finally just couldn't keep devoting so much time and effort to something that, for me, was tremendous for a few hours but had no lasting effect.

I take a B-12/B-6/Folic microlingual tablet made by Superior Source. I like it O.K., I think it helps...but only temporarily.

I've just started reading about Ferritin levels - stored iron in the body. If a person's ferritin levels are off, they'll have many symptoms that mimic B-12 deficience. I don't think doctors check for ferritin unless maybe the patient requests it.
