What it is

This is the one to confirm before you buy, not buy before you confirm. Eating much less over months can lower B12 intake, and a true deficiency causes fatigue that looks like everything else, but most people on a varied diet are replete. Ask your clinician for a level rather than guessing. If a lab says you are low, methylcobalamin is the active, well-absorbed form, and Thorne's sublingual is a clean option. If your level is fine, you do not need it.
