Vitamin B12
44 listings from 34 vendors, from $0.28/mg. No independent lab tests on record. Prices checked .
Vitamin B12 is sold for research in many vial sizes and pack counts, so the listings below are ranked by US dollars per milligram rather than sticker price. A low price per mg says nothing about what is in the vial: the lab column shows whether each vendor has passed an independent test, and the methodology explains what a pass means. For research use only; not medical advice.
