Semaglutide, the active ingredient in Ozempic and Wegovy, extended median lifespan by nearly 100 days in older female mice, according to a National Institutes of Health-funded study published in Nature. A team at the University of California, Berkeley, led by Danica Chen, began treatment when the mice were 20 months old, well into late life for the animals.
