Taking cyanocobalamin if you have a methylation issue or MTHFR defect (3) in your genes can also cause issues as your body attempts to methylate the B12 before it can utilize it completely
Methylmalonic acid (MMA) is a blood test that seems to be a better measure of vitamin B12 deficiency than serum vitamin B12 level
NNMT is expressed in multiple tissues but is particularly abundant in adipose and hepatic cells, where it participates in nicotinamide utilization and impacts NAD-related pathways
