A comprehensive study published in Cell Metabolism tracked 2,500 adults over 10 years, measuring various health markers. Researchers found that mitochondrial function tests predicted healthy aging outcomes more accurately than traditional biomarkers like cholesterol or blood pressure. Lead researcher Dr. David Sinclair notes that ‘interventions targeting mitochondrial quality, including Urolithin A supplementation, represent our most promising avenue for extending healthspan.’ The study found that individuals with optimal mitochondrial function maintained 40% better physical performance and cognitive function into their 70s and 80s.
