'Wonder Drug': Common Diabetes Pill Could Transform How We Age, Scientists Say

Key Points:

• Metformin, a drug widely used since the 1950s to treat type 2 diabetes, is being studied for its potential anti-aging and longevity-boosting effects, though more research is needed to confirm these benefits in humans.
• The drug activates AMP-activated protein kinase (AMPK), which helps lower blood glucose and may slow cellular aging by promoting autophagy, reducing oxidative stress, and improving insulin sensitivity.
• Metformin may also induce beneficial epigenetic changes and positively alter the gut microbiome, potentially reducing inflammation and age-related diseases, as suggested by preliminary studies in animals and small human trials.
• Despite promising observational and animal studies, definitive evidence from large-scale clinical trials on metformin’s effects on aging and longevity in healthy humans is still lacking.
• The upcoming Targeting Aging with Metformin (TAME) trial aims to provide more conclusive data by testing the drug’s impact on aging in 3,000 participants over six years, potentially confirming metformin’s role as a "wonder drug" for healthy aging.
