Core Blood Biomarkers Linked to Longevity
Markers such as high-sensitivity C-reactive protein, hemoglobin A1c, and fasting insulin reflect inflammation, glycemic control, and metabolic signaling pathways. Evidence from population studies associates sustained elevations with accelerated aging phenotypes, though individual variability and confounding factors limit direct inferences.
Epigenetic Clocks and DNA Methylation Patterns
Epigenetic clocks estimate biological age by analyzing methylation at specific CpG sites. These tools show correlations with chronological age and health outcomes in research cohorts, yet their predictive accuracy varies across populations and remains an area of active investigation rather than routine clinical use.
