7.5 Semaglutide shown to slow aging and extend lifespan in mice

Semaglutide, the active ingredient in Ozempic and Wegovy, extended lifespan by nearly 100 days in older mice while improving memory, muscle function, and reducing aging markers, according to an NIH-funded UC Berkeley study. The drug outperformed calorie restriction in memory and blood-sugar control, suggesting it acts through biological mechanisms of aging independent of appetite suppression.

  • Median lifespan extended by nearly 100 days in treated mice
  • Improved memory, muscle function, blood sugar control, and reduced inflammation
  • Outperformed calorie restriction in exploratory behavior and spatial memory
  • Metabolic rate remained unchanged (unlike calorie restriction)
  • Suggests separate aging pathway beyond appetite suppression
