HOMA-IR: The Blood Test Your Doctor Isn't Ordering (But Should Be)

HOMA-IR: The Blood Test Your Doctor Isn't Ordering (But Should Be)

Your doctor measures fasting glucose and HbA1c but never orders fasting insulin or calculates HOMA-IR. That's like checking temperature during pneumonia without doing a chest X-ray. Here's why this simple index is the key to early diagnosis.

Gastritis and Helicobacter pylori: A Complete Natural Treatment Protocol Based on Clinical Evidence

Gastritis and Helicobacter pylori: A Complete Natural Treatment Protocol Based on Clinical Evidence

Helicobacter pylori infects roughly half the global population and remains the leading cause of chronic gastritis, peptic ulcers, and a significant risk factor for stomach cancer. With antibiotic resistance rates climbing past 30-40% in many regions, evidence-based natural protocols are gaining clinical relevance.

Glutathione: The Master Antioxidant and 3 Phases of Detoxification

Glutathione: The Master Antioxidant and 3 Phases of Detoxification

Glutathione is a tripeptide present in every cell of the human body and widely considered the master intracellular antioxidant. It participates in all three phases of hepatic detoxification, protects cells from oxidative damage, and is essential for immune function. Why do its levels decline, and what does the science say about restoring them?

Medicinal Mushrooms: Reishi, Lion's Mane, Cordyceps — What Science Says

Medicinal Mushrooms: Reishi, Lion's Mane, Cordyceps — What Science Says

Medicinal mushrooms are among the fastest-growing categories in the nutraceutical industry. But what lies behind the millennia-old tradition: marketing hype or rigorous science? We examine the clinical evidence for Reishi, Lion's Mane, and Cordyceps — from beta-glucans and immune modulation to neurogenesis and cognitive enhancement.

Personalized Nutraceuticals: Why "One Vitamin for Everyone" Doesn't Work

Personalized Nutraceuticals: Why "One Vitamin for Everyone" Doesn't Work

Standard multivitamins contain nutrients in forms and dosages that ignore individual genetics, microbiome, and current deficiency status. We examine the personalized nutraceutical approach — from blood tests to custom-compounded capsules.

Leaky Gut: Intestinal Permeability — The Root of Autoimmune Disease

Leaky Gut: Intestinal Permeability — The Root of Autoimmune Disease

Increased intestinal permeability — commonly known as leaky gut — is no longer a fringe concept. Peer-reviewed research now places it at the center of autoimmune, metabolic, and neuroinflammatory disease. We examine the evidence and restoration protocols.

Cortisol and Adrenal Health: Why 'Adrenal Fatigue' Isn't a Diagnosis but a Real Problem

Cortisol and Adrenal Health: Why 'Adrenal Fatigue' Isn't a Diagnosis but a Real Problem

The term "adrenal fatigue" dominates integrative medicine discussions, yet it has never been recognized as a legitimate medical diagnosis. The real issue — HPA axis dysregulation — is well-documented in peer-reviewed literature and has measurable biomarkers, distinct phases, and evidence-based treatment protocols.

Testosterone in Men Over 40: When TRT Is Truly Necessary

Testosterone in Men Over 40: When TRT Is Truly Necessary

After age 40, testosterone declines by 1-2% annually. But age-related decline is not always benign. We examine when TRT is genuinely warranted, which labs are essential, and how to optimize testosterone naturally before committing to lifelong therapy.

Menopause Without Suffering: Bioidentical vs Synthetic Hormones

Menopause Without Suffering: Bioidentical vs Synthetic Hormones

Menopause affects every woman. But hot flashes, insomnia, anxiety, and bone loss are not inevitable. We examine the difference between bioidentical and synthetic hormone therapy, reinterpret the WHI study, and outline a personalized approach to menopausal hormone therapy.

PCOS: Why "Just Take Birth Control" Is Not Enough

PCOS: Why "Just Take Birth Control" Is Not Enough

In 70% of women with PCOS, the root cause is insulin resistance, not a hormonal imbalance. Standard birth control prescriptions mask symptoms without addressing the underlying mechanism. We examine the pathophysiology, proper diagnosis, and a comprehensive treatment protocol.

Pregnenolone: 'Mother of All Hormones' for Burnout and Chronic Fatigue

Pregnenolone: 'Mother of All Hormones' for Burnout and Chronic Fatigue

Pregnenolone — the precursor to every steroid hormone in the body — occupies a unique position at the intersection of endocrinology and neuroscience. During chronic stress and burnout, its levels decline among the first, triggering a cascade of hormonal disruption.

Migraine: Accurate Diagnosis and Treatment Beyond Painkillers

Migraine: Accurate Diagnosis and Treatment Beyond Painkillers

Migraine is not "just a headache." It is a neurovascular disease affecting 12% of the population. Standard painkiller treatment leads to medication-overuse headache. We examine accurate diagnosis, the CGRP pathway, and an evidence-based prevention protocol.

Nootropics: What Actually Works for the Brain According to Science

The nootropics market is valued at $6 billion and growing at 15% annually. But which of the hundreds of "smart drugs" are actually supported by clinical evidence? We examine citicoline, Lion's Mane, racetams, and modafinil — from mechanisms to protocols.

Cholesterol: When Statins Are NOT Needed and What Works Instead

Total cholesterol and standard LDL are outdated cardiovascular risk markers. LDL particle size, particle count (LDL-P), and ApoB/ApoA1 ratio tell a fundamentally different story. We examine when statins truly are not needed and what works instead.

NAD+ and Cellular Aging: What's Behind the Hype

NAD+ and Cellular Aging: What's Behind the Hype

NAD+ (nicotinamide adenine dinucleotide) is a central coenzyme of energy metabolism whose levels decline by roughly 50% by age 50. We examine the science behind the hype: sirtuins, NMN vs NR, IV NAD+, epigenetic clocks, and real-world protocols.
