NAC vs NAD vs Niacin vs NR vs NMN  vs NMNH. Due to the small alphabetical differences, these supplements are often mixed up and confused by most consumers. We will cover the essentials and explain about each of these supplements below. Contents NAD NAD vs NAD+ NAD+ for Anti Aging NAD+ Helps Restore Age-Related Muscle Deterioration NAD and Resveratrol NAD Supplements NAC Niacin (NA) NR NMN NAC vs NMN Gluthatione vs NAC NAC vs Niacin NR vs NMN Can you take NR and NMN together? Niacin vs NR vs NMN Stability and Storage of NMN and NR Naturally Boosting NAD Levels Related Articles NAD NAD is a type of coenzyme found in all living cells. NAD plays important roles in a variety of metabolic reactions, including energy production and DNA repair. NAD is derived from Nicotinamide Riboside (NR) and various...

Executive Summary Long COVID (post‑acute sequelae of SARS‑CoV‑2 infection, PASC) affects millions worldwide and remains one of the most complex post‑viral syndromes in modern medicine. While early narratives focused on a single culprit — persistent spike protein — current evidence suggests long COVID is multifactorial , involving immune dysregulation, metabolic dysfunction, microvascular injury, and in some cases residual viral antigens. Among emerging therapeutic strategies, nicotinamide riboside (NR) — a NAD+ precursor — has gained attention due to promising clinical trial signals targeting fatigue, sleep, and metabolic recovery. This article merges and updates insights from spike‑protein hypotheses and NR/NAD+ research, separating established evidence from speculation, and presenting a balanced, science‑grounded view for 2026. What Is Long COVID? Long COVID refers to persistent or new symptoms lasting three months or longer after acute SARS‑CoV‑2 infection, not explained by altern...

Metformin and berberine both have potential for controlling blood sugar levels and problems related to them. While metformin is a prescription drug with a longer history of clinical usage, berberine is a naturally occurring substance that is accessible without a prescription. To make it easier for you to know the differences, here's a comparison of two: Source: Berberine: Berberine is a chemical found in some plants like European barberry, goldenseal, goldthread, Oregon grape, phellodendron, and tree turmeric. Metformin: Metformin is not derived from plants or animals. It is a synthetic pharmaceutical medicine, which means it was created in a laboratory rather than derived from nature. Metformin was developed using chemicals discovered in the French Lilac plant (Galega officinalis), however the medicine is manufactured using chemical processes. Medical Use: Berberine: Berberine has been used in traditional Chinese and Ayurvedic medicine for centuries. It has gained attention for it...

Why insulin resistance, visceral fat, and metabolic dysfunction quietly drive most modern illnesses — and what actually improves outcomes. This article is a core cluster within the Preventive Medicine & Longevity pillar on OneDayMD. It explains why metabolic health sits upstream of cancer, cardiovascular disease, dementia, kidney failure, and accelerated aging. Executive Overview Over the past 50 years, the global disease burden has shifted from infectious illness to chronic, lifestyle-associated disease . Despite appearing unrelated, most of these conditions share common biological roots: Insulin resistance Visceral adiposity Chronic low-grade inflammation Mitochondrial dysfunction Endothelial damage This article explains why metabolic dysfunction is not just a risk factor, but a unifying driver of modern disease — and why improving metabolic health consistently reduces mortality across populations. What Is Metabolic Health? Metabolic health refers to the body’s ability to: Mainta...

What actually reduces cancer risk — organ by organ — based on human evidence, not headlines or supplements. This guide is a core cluster article within OneDayMD’s Preventive Medicine & Longevity hub. It focuses on risk reduction , not guarantees, and prioritizes interventions supported by epidemiology and clinical data. AACR Cancer Progress Report 2023 / 2024 How to Read This Guide Cancer prevention is probabilistic. No intervention eliminates risk entirely. Each section highlights: 🟢 High-evidence risk reducers (consistent human data) 🟡 Moderate evidence factors (context-dependent) 🔴 Low or no evidence claims (common myths) Lung Cancer Prevention 🟢 High-Evidence Factors Smoking avoidance and cessation (dominant risk modifier) Avoidance of secondhand smoke Radon exposure mitigation Smoking cessation reduces lung cancer risk at any age , though risk never fully normalizes. 🟡 Moderate Evidence Air pollution reduction (population-level effect) Occupational exposure control (a...
