Metformin, a drug used to treat Type 2 diabetes, shows potential to slow aging in monkeys, improving cognitive abilities, reducing brain shrinkage, and restoring youthful cellular states. The drug also reduces chronic inflammation and age-related issues in multiple organs. The study bridges rodent and primate research, suggesting metformin could inform future clinical trials aimed at extending health span.
