These formulations have different affinities to key proteins and receptors which facilitate the generation of biologically active intracellular cobalamin and thus, differ in their rates of tissue retention and bioavailability ( The formulation and dosage regimens of B12 used to treat Vitamin B12 deficiency vary widely depending on the aetiology of the deficiency as well as region of medical practice (Table 2)

Before we dive into expiration, let's get grounded in the fundamentals
Throughout this review, we differentiate bioactive peptides, defined as naturally occurring or food-derived sequences that exert physiological effects, from therapeutic peptides, which are purposefully engineered pharmaceutical agents intended for clinical application
