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

Key Points:

• Metformin, a widely used diabetes drug since the 1950s, is being studied for its potential anti-aging and longevity-boosting effects, with researchers calling it a possible "wonder drug" for slowing biological aging.
• The drug activates AMP-activated protein kinase (AMPK), which not only lowers blood glucose but also promotes cellular processes like autophagy, reduces oxidative stress, and improves insulin sensitivity, all of which may slow cellular aging.
• Metformin may also influence aging through epigenetic changes, such as stabilizing the enzyme TET2, which helps maintain genomic stability and reduce age-related diseases, as suggested by small studies showing slower biological aging in patients taking the drug.
• Additional benefits may come from metformin's impact on the gut microbiome, reducing inflammation and improving metabolic health, with animal studies indicating reduced tumor growth linked to these effects.
• Despite promising findings, definitive evidence of metformin's effects on human longevity is lacking, and large-scale clinical trials like the upcoming TAME study are needed to confirm its potential as a geroprotective drug.
