Unlike semaglutide which solely activates GLP-1R (one of the three pivotal receptors regulating glucose homeostasis), tirzepatide also activates glucose-dependent insulinotropic polypeptide (GIP) receptor (GIPR) to enhance metabolic benefits with reduced side-effects 5
Impaired kidney function is also associated with increased IGFBP levels (e.g., IGFBP-1, -2, -3, -4, and -6) (75, 77) and IGFBP-3 protease activity, which subsequently increases low-molecular-weight IGFBP-3 fragments (78), most likely due to a compromised renal IGFBP-clearance ( Figure 4 )
Cyanocobalamin is the most stable and least expensive form of B12, widely used in oral supplements and injections
