Your Blood Is Both a Mirror and a Driver of How Fast You Age
Key Insight
This review suggests blood-based tests and therapies may become central tools for tracking and slowing aging.
Scientists are finding that the stuff floating in your blood, proteins, metabolites, and tiny vesicles, doesn't just reflect your age. It actively sets the pace of aging across organs. In animal studies, swapping old blood for young blood or filtering out pro-aging factors restored tissue function and even extended lifespan. Human trials using plasma exchange are now showing early promise for age-related decline.
