Mechanism of Action: Cyanocobalamin is a synthetic form of Vitamin B12. As a crucial cofactor in DNA synthesis, red blood cell production, and neurological function, this form of Vitamin B12 facilitates critical biochemical pathways
Look for HPLC-MS verification showing greater than 98% purity (preferably 99%+) and endotoxin testing confirming bacterial contamination levels below safe thresholds
Its biological activity is primarily driven by the reactive thiol (-SH) group on the cysteine residue, which enables participation in electron transfer and conjugation reactions
