Feb 24, 2026Longevity Biomarkers: What to Test, What the Results Mean, and How to Track ProgressBiological age testing spans conventional labs (HbA1c, CRP, lipids) to newer epigenetic clocks and proteomic aging scores. Most conventional biomarkers are actionable today; epigenetic clocks measure biological vs. chronological age but their clinical utility for intervention-guiding remains limited. A pragmatic panel of validated tests provides meaningful signal about longevity trajectory.
Feb 24, 2026Longevity Biomarkers: What to Track, How Often, and What the Evidence Says They MeanNo single biomarker captures biological age, but a panel of accessible blood and functional markers — HbA1c, hs-CRP, homocysteine, IGF-1, DHEA-S, grip strength, and VO2 max — provides a practical composite picture. Epigenetic clocks offer precision but limited actionability at current cost.
Feb 12, 2026Biomarker Testing Before Supplementing: B12, Vitamin D, Homocysteine, Ferritin, and CRPSupplementing without baseline testing is guesswork. Vitamin D, B12, folate, ferritin, homocysteine, and hs-CRP are the most actionable starting points. This guide explains what each test reveals, what ranges mean, and which supplements to prioritize based on results.
