Science-backed research · 2025–2026

Oh Darling,
It's Biology.

Your body isn't broken. It's under-explained. The research exists — it's just rarely joined up. Five condition clusters. Eight research guides. One coherent map.

The Missing Piece

These conditions don't travel together by coincidence.

Every cluster on this site shares upstream biological drivers — chronic inflammation, mitochondrial dysfunction, nervous system dysregulation and a gut-brain connection. Treating them in isolation is why so many people don't improve.

🦠
Gut-Brain Axis Disruption
Dysbiosis reduces serotonin, GABA and SCFA production — driving mood, pain, immunity and hormonal dysfunction simultaneously across all clusters.
🔋
Mitochondrial Energy Failure
Chronic inflammation damages the electron transport chain. Reduced ATP means tissue can't repair, brains can't regulate, and fatigue becomes structural — not motivational.
⚡
Nervous System Dysregulation
Central sensitisation, HPA axis hyperactivation and autonomic dysfunction amplify every signal — pain, emotion, sensation — turning the volume up body-wide.
Five condition clusters

Each cluster has a free research guide and a phased supplement stack — evidence-matched, introduced one at a time.

Cluster 1
Fascia & Mitochondria
hEDSPOTSMCASMigraine

Where connective tissue, the interstitium and mitochondrial energy collide. The CHA axis, piezoelectric collagen, and the fascia-mast cell loop explain why these conditions share a broken biology.

Cluster 2
Gut-Brain & Hormones
FibromyalgiaPMOSDepressionAnxietyIBSOCD

One broken gut-brain system expressing in six ways. The HPA axis, insulin resistance, central sensitisation and gut dysbiosis are the shared upstream drivers — not separate diagnoses.

Cluster 3
AuDHD & Brain Health
AutismADHDAuDHDBurnoutBrain Health

AuDHD is not ADHD plus Autism — it's a distinct neurobiological profile. The masking-to-burnout-to-mitochondrial damage pathway and the dementia prevention protocol.

Cluster 4
Mental Health as Physical Health
DepressionAnxietyOCDBurnoutMetabolic Psychiatry

Harvard, Edinburgh, Stanford and Nature Mental Health are all pointing in the same direction — mental illness is a metabolic and mitochondrial condition. The body is where mental health lives.

Cluster 5 · New 2026
Perimenopause
PerimenopauseHeart PalpitationsHistamineBrain FogSleep

Oestrogen wasn't just a reproductive hormone — it was managing your nervous system, immune system, metabolism, heart and brain simultaneously. What you're experiencing is the withdrawal of that management.

New research.
When it matters.

Science moves faster than clinical guidelines. When new peer-reviewed research changes what we know about these conditions, you'll hear about it first.
