Special populations, such as post-bariatric surgery patients and those on metformin, may require tailored dosing regimens to ensure adequate vitamin B12 levels
It plays a key role in processes like making red blood cells, creating DNA and producing nerves
Its small size confers favorable physicochemical properties for solubility, stability, and intranasal or subcutaneous delivery, but also raises questions about specificity that are common to short peptides in vivo proteolytic stability, off-target binding, and minimum receptor recognition motif identification all require additional characterization that the published literature does not yet fully provide
Human clinical evidence remains limited, and individual results cannot be guaranteed
If you are injecting intramuscularly or subcutaneously, determine the appropriate injection site
