Age-Related Hearing Loss: Mechanisms, Cognitive Links, and Nutritional Support
Age-related hearing loss (presbycusis) affects over 60% of adults over 70 and independently accelerates cognitive decline. This article reviews the mechanisms and the limited but growing evidence base for nutritional support.

Kidney Health and Aging: GFR Decline, Protein Intake, and Renoprotective Strategies
GFR declines ~1 mL/min/year after age 40. In early-stage CKD, protein restriction, blood pressure control, and avoiding nephrotoxic supplements (high-dose oxalate, aristolochic acid) are the primary levers. Potassium citrate and omega-3 have supportive evidence.

Longevity Biomarkers: What to Test, What the Results Mean, and How to Track Progress
Biological 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.

Nocturnal Blood Pressure Non-Dipping: The Hidden Cardiovascular Risk You Can Measure
Blood pressure normally falls 10–20% during sleep. When this nocturnal dip is absent, cardiovascular and renal risk increase substantially — even if daytime readings appear normal. This article explains the mechanism and evidence-based management strategies.

Orthostatic Intolerance in Aging: Causes, Risks, and Evidence-Based Management
Orthostatic intolerance — dizziness or near-fainting upon standing — affects up to 20% of adults over 65 and substantially increases fall risk. This article reviews the mechanisms and evidence-based management strategies.
