AARP spoke with four geriatric specialists with expertise in vitamin B12 to learn about its importance and the steps to take if youre worried you may not be getting enough
Semaglutide 2.4mg (GLP-1 Agonist): Proven GLP-1 effects (appetite suppression, gastric emptying) Already FDA-approved as Wegovy Established safety profile Cagrilintide 2.4mg (Amylin Analog): Mimics amylin, a hormone co-secreted with insulin Slows gastric emptying through different pathway than GLP-1 Reduces appetite through hindbrain (not hypothalamus) Improves postprandial glucose The Advantage: Leverages proven semaglutide efficacy and safety, adds complementary amylin effects
Theyre great for people who have trouble absorbing B12 because of age or digestive problems
Together, these interventions lower allostatic load and reinforce adaptive stress-response pathways
Minimal Systemic Exposure Because of its short half-life and localized action, you dont get the widespread IGF-1 elevation that can cause issues with organ growth or insulin resistance seen with the systematic use of full-length IGF-1 for extended periods of time
This appetite suppression typically begins within days and often deepens over the first 48 weeks as your body adjusts to the new hormonal signals
