It is made from Cynocobalamin, and sometimes i eat it on an empty stomach, i cant speak to that w/ consistency, as sometimes i skip breakfast. I only heard of iherb.com from reading this forum, and will certainly look into the methylcobalamin form.

I asked my doctor WHY my b12 levels got low, if I have the Intrisic Factor, and she says they dont know. This is sort of unacceptable! Am I wrong to feel this way? I admit I am a worrier and hypochondriac, but I am concerned!

I worry is there something wrong with my liver something? I've had a Liver Function Test and an Ultrasound of my whole abdomenal/pelvic area, and no abnorablities are found. Is this just a rough vitamin to absorb for some?

I have difficulty with setteling with "we dont know" - and want to get to the bottom of it. Thanks again for the info
