Feb 11, 2026Circadian Rhythm and Longevity: Disruption Effects, Melatonin, and Timed SupplementationCircadian disruption — from shift work, artificial light, and irregular sleep — accelerates biological aging and increases disease risk. Melatonin, light hygiene, and chronobiologically timed supplement dosing (e.g., resveratrol at night) may partially mitigate disruption effects.
Feb 10, 2026Telomere Biology and Aging: Attrition Rate, Telomerase, and What Supplements ShowTelomeres shorten with each cell division, and critically short telomeres trigger senescence or apoptosis. Telomerase can extend them but its activation is complex and cancer-relevant. This article covers the biology, what supplements like vitamin D and astragalus show, and honest limitations.
Feb 9, 2026Epigenetic Clocks and Biological Age: Horvath, GrimAge, DunedinPACE — What They MeasureEpigenetic clocks measure DNA methylation patterns that change predictably with age. Different clocks predict different endpoints — Horvath measures biological age, GrimAge predicts mortality, DunedinPACE measures aging speed. Understanding what they do and don't measure is essential before acting on results.
Feb 9, 2026Gene Therapy for Aging: Telomerase Activation, AAV Delivery, Current Trials, and RisksGene therapy to extend healthspan is moving from animal studies to human trials. Telomerase activation via AAV delivery extended lifespan in mice. Human applications are in early development. The risks — including oncogenic potential — are significant and must be understood clearly.
Feb 8, 2026Epigenetic Reprogramming: Yamanaka Factors, Partial OSK Reprogramming, and the Clinical HorizonPartial epigenetic reprogramming using OSK (Oct4, Sox2, Klf4) Yamanaka factors has reversed multiple aging hallmarks in animal models without inducing cancer. Human translation is in early clinical development. This article explains the biology, current trials, and realistic timeline.
Feb 4, 2026The 12 Hallmarks of Aging: Which Supplements Address Each and the EvidenceThe 12 hallmarks of aging — from genomic instability to chronic inflammation — each represent targetable mechanisms. This article maps which supplements have mechanistic or clinical evidence for each hallmark, providing an evidence-calibrated framework for building a longevity protocol.
