Molecular Decoding
In-depth analysis of ingredients and their mechanisms of action. What the science says vs what the marketing says.
Iron panel: how to read ferritin, transferrin saturation and hemoglobin together
An iron panel is read by comparing ferritin, transferrin saturation, hemoglobin and inflammation. This method helps explain apparently discordant results.
Lp(a): The Genetic Cardiovascular Risk You Measure Only Once
Lipoprotein(a) is a cardiovascular risk factor set by your genes and stable for life. A single measurement is enough to know your status.
Fasting Insulin and HOMA-IR: Reading Insulin Resistance Before Glucose
Fasting glucose is a lagging indicator. Fasting insulin and HOMA-IR reveal insulin resistance years before blood sugar begins to drift out of range.
Ferritin: Why Its Reference Range Reads in Two Directions
Ferritin reflects the body's iron stores. Its very wide reference range masks a narrower functional zone that must be read in two opposite directions.
TSH: Why Your Optimal Level Is Not the Population's
TSH regulates the thyroid axis. Each individual has a narrow personal set-point, located inside a much wider population reference range.
Vitamin D: the optimal range for longevity
Why Singular uses 20 to 50 ng/mL as its internal 25(OH)D target, based on an indirect synthesis that does not establish a causal longevity benefit.
Which Supplements Should You Take: A Biomarker-First Method
Singular uses a biomarker panel to contextualize and calibrate a formula. This service method does not turn five tests into a universal medical prescription.
Low-Grade Inflammation: The Silent Fire Your Blood Panel Does Not Detect
Chronic low-grade inflammation is a biological process invisible to standard blood tests. hs-CRP, homocysteine and the copper/zinc ratio can detect it before it becomes entrenched.
Supplement Interactions: What No One Tells You About Combining Nutrients
Some nutrients cancel each other out when taken together. A factual map of documented antagonisms and synergies between dietary supplements.
Grey Hair: Is It Possible to Slow or Reverse the Process?
Science has recently identified the exact mechanism behind hair greying. Stuck stem cells, oxidative stress and nutritional deficiencies are at the heart of the process. A review of the current evidence.
DNA Testing and Supplementation: What Consumer Genomics Can (and Cannot) Tell You
Genetic testing kits promise personalized nutritional recommendations. Science tells a more nuanced story, where blood biomarkers remain the most reliable measure for calibrating precision supplementation.
The Multivitamin Myth: Why the 'One Size Fits All' Approach Is a Biological Absurdity
Multivitamins are the world's best-selling supplement. Yet their fundamental logic contradicts the most basic principles of individual biochemistry.
NAD+ and Cellular Aging: From Mechanism to Human Evidence
NAD+ plays a central role in cellular metabolism. But its trajectory with age varies across tissues, and raising it in blood does not by itself demonstrate a clinical benefit.
Homocysteine: The Inflammatory Signal Your Standard Panel Ignores
Homocysteine is an integrative marker of the methylation cycle. Its elevation reveals a metabolic dysfunction involving B9, B12 and B6 that routine bloodwork does not measure.
Magnesium and longevity: the mineral your biology demands in silence
Magnesium is involved in over 600 enzymatic reactions. Its chronic deficiency accelerates cardiovascular, metabolic and cerebral aging. A deep dive into forms, data and implications.
Creatine: what survives replication
Two regulators refused creatine's cognitive claim in 2024. Its performance foundation, by contrast, holds at 3 g per day, and even below.
Kidney Function: Why Creatinine Is an Obsolete Metric for Athletic Profiles
Creatinine has been the default kidney function marker for decades. But for muscular and active individuals, it systematically generates false positives. Cystatin C changes the equation.
The Daily Glass Myth: Why Alcohol Has No Protective Threshold
The French paradox and the supposed benefits of red wine rest on methodological biases. Current evidence is unequivocal: there is no level of alcohol consumption free of health risk.
The Absolute Dosage Illusion: The Difference Between What You Ingest and What You Absorb
Displaying 500 mg of magnesium on a label says nothing about what actually reaches your cells. The molecular form of a bioactive determines its biological fate far more than its raw dosage.
Apolipoprotein B: The Only Lipid Marker That Dictates Your Cardiovascular Trajectory
LDL cholesterol tells only part of the story. Apolipoprotein B measures the actual number of circulating atherogenic particles. That number is what predicts risk.
