Mitochondrial Dysfunction
The decline in efficiency of mitochondria, the cell's energy-producing structures, with age, reducing cellular energy output and increasing oxidative byproducts.
| Focus | Cell-level aging mechanism |
|---|---|
| What It Tracks | Declining efficiency and number of functional mitochondria within cells |
| Why It Matters | Reduced mitochondrial function is linked to lower energy availability in tissues and is a recognized hallmark of aging |
| Typical Setting | Research and preclinical study; indirectly reflected in some fitness and metabolic testing |
