Blue Zones Healthspan longevity

What Actually Extends Healthspan

The longevity field is full of compounds that work in worms. What holds up in humans is a shorter and much less exciting list.

Brown Fat Cardiovascular Cold Exposure

Cold and Heat: Where the Evidence Is Strong and Where It Is Not

Sauna has population-scale data behind it. Cold exposure has enthusiasm, real mechanisms, and much thinner outcome evidence — and one interaction worth knowing.

Alcohol Circadian Rhythm Glymphatic

Sleep: The Highest-Yield Thing on This Site

Nothing else returns as much for as little. It is also the one people are proudest of neglecting.

Autophagy: The Cleanup System, and What Actually Switches It On

Cells recycle their own damaged parts, and the process runs hardest when nutrients are scarce. The mechanism is Nobel-winning; the timing claims made about it are mostly invented.

Blood Sugar Depression Inflammation

Mental Health: The Metabolic Angle Nobody Screens For

The brain uses a fifth of the body's energy. When energy metabolism falters, the symptoms are psychiatric — and psychiatry has begun to notice.

Parasite Cleansing: The Traditional Approach, Done Properly

Every traditional medical system had a way of clearing parasites, and many of the plants they used show antiparasitic activity in the laboratory. Here is what they are, what the evidence in people actually shows, and how to run a cleanse well.

Cancer Insulin ketogenic-diet

Cancer: The Metabolic Question Alongside the Genetic One

The genetic model has driven cancer research for fifty years. A parallel line of work asks why tumour cells metabolise fuel so strangely — and what follows if that is a cause rather than a consequence.

Autoimmune Gluten Inflammation

Autoimmunity: Starting at the Barrier

Different autoimmune conditions attack different tissue, but they share a mechanism — and one of the few modifiable inputs sits in the gut wall.

Hashimoto Iodine Selenium

Thyroid: Why TSH Alone Misses Most of the Problem

One number is used to rule the whole system in or out, and it sits two steps upstream of anything you would actually feel.

Bioavailability Dosing Labels

How to Choose a Supplement Without Being Sold One

Most of what is on the shelf is unnecessary, underdosed or in a form the body handles poorly. A few things are genuinely worth taking. Here is how to tell them apart.

NAD+, NMN and NR: Promising Biology, Thin Human Evidence

NAD+ genuinely declines with age and genuinely matters. Whether swallowing a precursor changes anything you would notice is a separate and much less settled question.

Adaptogens Ashwagandha cortisol

Adaptogens: A Vague Word and a Few Real Herbs

The category is loose enough to sell almost anything. Two or three of the herbs in it have genuine human evidence, and they are not interchangeable.

Amino Acids Bone Broth Collagen

Collagen: What It Can and Cannot Do

The digestion argument against it turns out to be partly wrong — but the reason it works is not the reason it is sold.

Fermented Foods Gut Microbiome Prebiotics

Probiotics: Strain-Specific, or Nothing

The species on the front of the box tells you almost nothing. Effects are documented at the strain level, and most products do not name theirs.

Omega-3: The Ratio Matters More Than the Amount

Taking fish oil while eating industrial seed oil is filling a bath with the plug out. The ratio between the two families is what the body actually responds to.

Dha Epa omega-3

B Vitamins: Why the Form on the Label Matters

They work together and fail together — and a substantial share of people handle the synthetic forms poorly.

B Vitamins B12 Folate

Collagen High Dose Immune Function

Vitamin C: Two Different Arguments, Often Confused

The role in collagen synthesis and immune function is settled. The claims made for high-dose intravenous protocols are a separate question with much weaker support.

Brazil Nuts glutathione Selenium

Selenium: A Narrow Window and Two Important Jobs

Required to activate thyroid hormone and to run the body's own antioxidant system — with a therapeutic range tighter than most minerals.

Anaemia Blood Testing Ferritin

Iron: Where Both Deficiency and Excess Do Damage

The nutrient most likely to be supplemented without testing, and one of the few where being too high is as harmful as being too low.

Copper Immune Function Mineral Balance

Zinc and the Copper Problem

Central to immunity, healing and hormone synthesis — and in direct competition with copper for absorption, which is why sustained high doses create a new deficiency.

Magnesium: Which Form for What

Involved in hundreds of reactions and depleted by exactly the things modern life supplies. The form on the label determines what it actually does.

Citrate Cramps Glycinate

Arterial Calcification Fermented Foods Mk-7

Vitamin K2 Decides Where the Calcium Goes

Largely absent from modern diets because it comes from fermented food and pastured animal fat — and it is the difference between calcium in bone and calcium in artery wall.

Blood Testing Magnesium Sunlight

Vitamin D: The Dose Nobody Can Give You

Less a vitamin than a hormone, and one of the few supplements where deficiency is genuinely widespread at northern latitudes. The right dose varies more between people than for anything else on the shelf.

Adherence Diet Selection Elimination Diet

How to Choose Between Diets Without Joining a Camp

The patterns that work disagree loudly and overlap quietly. Choosing well is mostly a matter of knowing which variable is your problem.

Food Quality Refined Carbohydrate seed-oils

Whole Foods: The Precondition, Not the Diet

Almost every eating pattern with evidence behind it removes the same five things. That overlap explains more than the differences between them do.

Epidemiology Mediterranean Diet Olive Oil

The Mediterranean Diet: What the Studies Actually Observed

The most consistently supported dietary pattern in the literature, and the most frequently misrepresented by the food sold in its name.

Autoimmune Carnivore Elimination Diet

Carnivore Is an Elimination Diet Taken to Its Endpoint

Its strongest case is as a diagnostic tool for people who have run out of variables to remove — not as a permanent way of eating for everyone.

Appetite Electrolytes Epilepsy

Keto Is a Metabolic Intervention, Not a Diet Trend

Restricting carbohydrate far enough to run on ketones changes insulin, appetite and, in some conditions, symptoms that food is not supposed to touch.

fasting Meal Composition Micronutrients

OMAD: One Meal a Day, Done Properly

The simplest fasting pattern to follow and the hardest to do well, because a single sitting has to carry an entire day's nutrition.

Adherence autophagy Caloric Restriction

Fasting-Mimicking: Does the Compromise Hold?

Eating little enough to trigger part of the fasting response while still eating. The appeal is adherence; the question is how much survives the compromise.

autophagy Electrolytes Refeeding Syndrome

Water Fasting: An Honest Account of What Is Known

The most demanding protocol and the one with the thinnest modern evidence base relative to its reputation.

autophagy Electrolytes Extended Fasting

Extended Fasting: What Changes After Forty-Eight Hours

Past two days the metabolic picture changes in kind rather than degree — and so do the risks worth taking seriously.

Circadian Rhythm Glucose insulin-sensitivity

Time-Restricted Eating: The Circadian Case

The same meal is handled differently at eight in the morning than at ten at night. Time-restricted eating is built on that difference rather than on calories.

Insulin Intermittent Fasting meal-timing

Intermittent Fasting: What the Window Actually Does

Most of the benefit attributed to the eating window comes from what falls out of the diet when it closes, not from the clock itself.

Creatine Beyond Five Grams: What the Newer Research Is Finding

The muscle dose has been settled for thirty years. The brain research keeps pointing at a higher one — and at effects that have nothing to do with lifting.
