Feb 24, 2026Heat Stress and Aging: Why Older Adults Are More Vulnerable and How to AdaptThermoregulatory capacity declines with aging: sweating onset is delayed, cardiovascular reserve is reduced, and thirst is blunted. This article covers why older adults face higher heat mortality risk and what evidence supports safe heat adaptation.
Feb 24, 2026Nocturnal Blood Pressure Non-Dipping: The Hidden Cardiovascular Risk You Can MeasureBlood 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.
Feb 24, 2026Orthostatic Intolerance in Aging: Causes, Risks, and Evidence-Based ManagementOrthostatic 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.
Feb 24, 2026Sodium-Potassium Balance in Aging: The Dietary Lever for Blood Pressure and Vascular HealthThe ratio of dietary sodium to potassium is a more powerful predictor of cardiovascular risk than sodium intake alone. This article reviews the evidence for the Na/K balance as a therapeutic target and practical approaches to correction.
Feb 24, 2026Tobacco, Smoking, and Aging: Health Damage and Evidence-Based Cessation SupportTobacco is the leading preventable cause of accelerated aging, cardiovascular disease, and cancer. This article covers the biological mechanisms and evidence-based support for cessation and harm mitigation.
Feb 23, 2026Periodontal Disease and Aging: The Overlooked Systemic RiskPeriodontal disease is a chronic inflammatory condition linked to cardiovascular disease, diabetes, and cognitive decline. Here is what the evidence shows about management beyond brushing.
Feb 23, 2026Sedentary Behavior and Step Count in Aging: What the Evidence Says About Movement ThresholdsLow daily step count and prolonged sitting independently predict cardiovascular disease, metabolic dysfunction, and premature mortality. This article reviews the evidence thresholds and practical movement strategies for aging adults.
Feb 22, 2026Longevity Protocol for Men Over 50: Evidence-Based PrioritiesMen over 50 face accelerating cardiovascular, metabolic, and hormonal changes. This protocol covers the highest-leverage, evidence-based interventions for men in the second half of life.
Feb 22, 2026Vitamin E: Tocopherol vs Tocotrienol Forms, Antioxidant Evidence, and Supplementation RisksVitamin E encompasses eight molecules: four tocopherols and four tocotrienols. Synthetic dl-alpha-tocopherol dominates the supplement market but has underperformed in trials. Tocotrienols — especially delta and gamma forms — show more promising cardiovascular and neuroprotective signals.
Feb 19, 2026Metabolic Syndrome: A Comprehensive Evidence-Based ProtocolMetabolic syndrome affects 1 in 3 adults and accelerates aging across every system. This protocol covers the interconnected drivers and the best-evidenced interventions for each component.
Feb 18, 2026POLYCAD Trial: Spermidine Supplementation in Coronary Artery Disease — Design and Interim ContextThe POLYCAD trial is testing 24 mg/day spermidine in 187 older adults with coronary artery disease for 48 weeks. Trial completion is expected August 2026 — no efficacy results exist yet. Prior cohort data from Eisenberg et al. 2016 provides the rationale.
Feb 13, 2026Omega-3 Fatty Acids: EPA, DHA, Cardiovascular Outcomes, and Cognitive Aging EvidenceEPA and DHA are the two clinically relevant omega-3 fatty acids. High-dose EPA (REDUCE-IT trial, 4 g/day icosapentaenoic acid) significantly reduced cardiovascular events. DHA drives brain structural benefits. Standard fish oil doses produce modest effects; high-dose prescription forms show stronger outcomes.
Jan 21, 2026Taurine and Aging: Depletion with Age, Cardiovascular Evidence, and Longevity ResearchTaurine levels decline with age and the ICV mouse study showed lifespan extension with supplementation. Human cardiovascular evidence (blood pressure, heart function) is modest but consistent. The longevity case is promising but not yet established in humans.
Jan 16, 2026Citrulline Malate and Nitric Oxide: Exercise Performance Evidence in Older AdultsCitrulline raises plasma arginine and nitric oxide more efficiently than arginine supplementation. Human trials show improvements in exercise capacity, blood pressure, and endurance, particularly relevant for older adults with declining NO production.
Jan 7, 2026Vitamin K2 and Arterial Calcification: MK-4 vs MK-7, Bone and Vascular HealthVitamin K2 activates Matrix Gla Protein, which inhibits arterial calcification, and osteocalcin for bone mineralization. MK-7 has superior half-life and bioavailability vs MK-4.
