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 20, 2026Arterial Stiffness Risk: Cocoa Flavanols, Aged Garlic, Olive Leaf, and BeetrootAerobic training and blood-pressure control remain primary for arterial stiffness. Cocoa flavanols, aged garlic, olive leaf, and beetroot may provide modest vascular support.
Feb 14, 2026Magnesium: Deficiency in Aging, Form Comparison, and Evidence for Sleep, Blood Pressure, and MuscleMagnesium is the fourth most abundant mineral in the body and cofactor for over 300 enzymes. Dietary insufficiency is widespread — over 50% of adults consume below the RDA. Supplementation improves sleep quality, blood pressure, and muscle function, with form choice determining tolerability and absorption.
Jan 20, 2026Blood Pressure: Natural Interventions — Potassium, Magnesium, Beetroot Nitrate, and DASHLifestyle and supplement approaches to blood pressure are evidence-supported and often underused. Potassium intake, dietary magnesium, beetroot nitrate, and the DASH dietary pattern each have RCT-level evidence for modest but meaningful blood pressure reduction.
