Free radicals are a primary driver of biological aging
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Current biological evidence supports the free radical theory of aging, demonstrating that reactive oxygen species and chronic oxidative stress drive cellular senescence, functional decline, and age-related pathology.
