The Mitochondrial Free Radical Theory of Aging

The Mitochondrial Free Radical Theory of Aging suggests that as we age, mitochondria—the energy-producing parts of our cells—produce harmful molecules called free radicals during energy production. These free radicals can damage cell components, including DNA, proteins, and membranes. Over time, this accumulated damage impairs cell function and contributes to the aging process and related diseases. Essentially, the theory links the gradual buildup of mitochondrial damage from free radicals to the decline in cellular health and the aging of the entire organism.
