// Evidence Hierarchy

Not all studies are created equal.

We prioritize the top tiers. Here is how the hierarchy of scientific evidence works.

1.
Systematic Reviews

Comprehensive analysis of all available studies on a question, with strict inclusion criteria and bias assessment.

We cite this
2.
Meta-Analyses

Statistical pooling of multiple RCTs to compute a weighted average effect across thousands of participants.

We cite this
3.
Randomized Controlled Trials

Gold standard experiments — participants randomly assigned to treatment or control, isolating cause and effect.

Our evidence threshold
4.
Cohort Studies

Observational research tracking groups over time. Useful for trends, but cannot prove causation alone.

5.
Case Studies

Individual patient reports. Valuable for rare conditions and hypothesis generation, not for drawing conclusions.

// Study Breakdowns

The science we stand on.

Each breakdown takes a peer-reviewed paper and explains the finding, the mechanism, and why it matters for your health.

HORMONESMeta-Analysis

Insulin Resistance & Androgen Elevation

Hyperinsulinemia directly upregulates ovarian androgen production via theca cell stimulation — independent of body weight.

PMID 31296325Read breakdown →
STRESSSystematic Review

Cortisol Dysregulation & Chronic Stress

Chronic psychological stress flattens the diurnal cortisol curve, impairing immune function, sleep architecture, and metabolic regulation.

PMID 27557747Read breakdown →
NUTRITIONRCT

Linoleic Acid & Systemic Inflammation

Excess omega-6 linoleic acid from seed oils increases tissue arachidonic acid and pro-inflammatory eicosanoid production.

PMID 29610056Read breakdown →
GUT HEALTHSystematic Review

The Gut-Skin Axis: Intestinal Dysbiosis

Intestinal permeability and microbial imbalance trigger systemic inflammation that manifests as acne, eczema, and psoriasis.

PMID 34572345Read breakdown →
CIRCADIANRCT

Blue Light & Melatonin Suppression

Evening blue light exposure (460nm) suppresses melatonin onset by 90+ minutes, fragmenting sleep architecture and reducing REM density.

PMID 25535358Read breakdown →
TOXINSCohort Study

Microplastics in Human Blood

Quantifiable microplastic particles detected in 77% of human blood samples — with PET and polystyrene as dominant polymer types.

PMID 35316545Read breakdown →
CIRCADIANMeta-Analysis

Circadian Cortisol Curve

The cortisol awakening response (CAR) is a reliable biomarker of HPA axis function — blunted CAR predicts fatigue, depression, and metabolic syndrome.

PMID 26647166Read breakdown →
HORMONESSystematic Review

Birth Control & Nutrient Depletion

Oral contraceptives significantly deplete B6, folate, zinc, magnesium, and selenium — nutrients critical for methylation, mood, and immune function.

PMID 23852908Read breakdown →
