Anti-Aging drug shows promise in prolonging animal life
A big review of animal studies says cutting calories (or sometimes fasting) is the most reliable way to boost lifespan.
The drug rapamycin—usually given after organ transplants—also showed similar effects, while metformin (a common diabetes med) didn't really move the needle.
Findings of the study
Eating less or fasting helped both male and female animals live longer.
Rapamycin also worked in many cases, but not always.
Metformin was expected to help too, but it didn't consistently extend lifespan like researchers hoped.
Rapamycin is being tested as an anti-aging treatment
Rapamycin looks promising as an anti-aging treatment because it can mimic some benefits of eating less.
Early human trials suggest that small, spaced-out doses might improve health without major side effects—though doctors are still cautious about immune system risks.
Scientists are now testing safer ways to use rapamycin and similar drugs to see if they can help people stay healthier for longer.
