“Cyanocobalamin is the FDA-approved B12 injection pharmacies have trusted for decades - affordable, reliable, and a straightforward way to bypass digestion when oral B12 is not getting the job done. It is a great place to start, and if you are ever curious whether methyl makes more sense, we can help you compare without making B12 more complicated than it needs to be.”
