The AURION™ System

Supplementation That Knows Your Biology.

AURION™ is The Catalyst Clinic's proprietary precision supplementation engine. It integrates your bloodwork results, medical history, current medications, lifestyle data, and advisory protocol into a single unified picture of your biology — and generates supplementation recommendations that are specific to you, not to a demographic, a goal category, or a marketing archetype.

Most supplementation programmes — even those offered by premium clinics — are built on templates. A goal is stated, a stack is assigned. The individual biology behind that goal is rarely interrogated. AURION™ was built to close that gap. Every recommendation it produces is reviewed and approved by Dr. Ethan personally before it reaches you.

The result is a programme structured into precise morning and evening formulations, designed to work in concert with your advisory protocol, reviewed monthly as your biomarker data evolves. No unnecessary supplements. No conflicting compounds. No guesswork.

What AURION™ Integrates

  • Full pre-consultation bloodwork results
  • Complete medical history
  • Current medications and supplements
  • Lifestyle data — sleep, activity, diet
  • Advisory protocol compounds
  • Contraindication and interaction screening
  • Stated health and longevity goals
  • Previous supplementation history
  • Monthly review data and biomarker changes
  • Dr. Ethan's personal clinical assessment

How It Works

From Your Bloodwork To Your Programme.

The AURION™ supplementation process is an integrated extension of your advisory consultation — not a separate service, not an afterthought, and not a generic add-on. It begins with your diagnostics and it never stops evolving.

Step 01

Comprehensive Diagnostics

Mandatory pre-consultation bloodwork covering all biomarkers relevant to your goals and health profile. No supplementation programme is designed without this data. This is where everything begins.

Step 02

Personal Review by Dr. Ethan

Dr. Ethan reviews your results personally — not via algorithm, not via delegation. He identifies nutritional gaps, imbalances, and interactions specific to your biomarker profile and health history.

Step 03

AURION™ Programme Design

Your data is processed through AURION™ alongside your advisory protocol to generate a fully personalised AM and PM supplementation programme. Dr. Ethan reviews and approves every recommendation before it reaches you.

Step 04

Monthly Evolution

As your bloodwork changes, your supplementation programme changes. Monthly physician reviews ensure your programme evolves with your biology — not against it. Your plan is never static.

Why AURION™ Is Different

The Standard That No Generic Stack Can Meet.

The supplementation market is saturated with products that promise personalisation and deliver templates. AURION™ was built on a different principle — that personalisation without diagnostics is not personalisation at all.

01

Bloodwork-Led, Not Goal-Led

Most programmes start with your goals and assign a stack. AURION™ starts with your biology. Goals inform context — your biomarkers determine the recommendations.

02

PhD-Level Personal Oversight

Every AURION™ recommendation is reviewed and approved by Dr. Ethan Hausman-Marquis personally — PhD, Cell & Genomic Biology, Karolinska Institute. No algorithm makes the final call.

03

Interaction Screening

Your current medications, advisory protocol compounds, and supplementation history are all screened for interactions before any recommendation is made. Nothing conflicts. Nothing is redundant.

04

AM & PM Formulation Architecture

Your programme is structured into precise morning and evening formulations designed around circadian biology, absorption timing, and your daily routine. Not a single list — an intelligently sequenced programme.

05

Monthly Biomarker Alignment

Every four to five months your bloodwork is repeated. Your supplementation programme is reviewed and updated in response. A programme designed six months ago may not be the right programme today.

06

Advisory Protocol Integration

Your supplementation programme is designed to work in concert with your advisory protocol — not independently of it. AURION™ accounts for every compound in your programme when making recommendations.

The Diagnostic Foundation

Why Bloodwork Comes Before Everything.

Supplementation without diagnostics is directional guesswork. You may be supplementing nutrients you already have in excess, missing the ones you are actually deficient in, or introducing compounds that interact with medications you are already taking. At The Catalyst Clinic, this is not acceptable. Comprehensive bloodwork is mandatory before any supplementation programme is designed — because a programme built on your data is categorically different from one built on your goals alone.

The AURION™ Difference

What Separates A Genuine Programme From A Template.

Most supplementation — including that offered by premium wellness brands — is fundamentally a template with a personalisation veneer. The questions change. The stack does not. AURION™ was built to do something categorically different.

Generic Supplementation Programmes

  • Designed around your stated goals — not your biology
  • No mandatory bloodwork before recommendations
  • Template-based stacks assigned by category
  • No physician involvement in design
  • No medication or compound interaction screening
  • Static — does not evolve with your data
  • No integration with wider health programme
  • No ongoing clinical oversight

The Catalyst Clinic — AURION™

  • Designed from your mandatory pre-consultation bloodwork
  • Comprehensive diagnostics required before any recommendation
  • Fully bespoke — no two programmes are identical
  • Personally designed and approved by Dr. Ethan
  • Full medication, compound, and supplement interaction screening

Common Questions

Supplementation FAQ

AURION™ is The Catalyst Clinic's proprietary precision supplementation engine. It integrates your bloodwork results, medical history, current medications, lifestyle data, and advisory protocol to generate a fully personalised supplementation programme. Every recommendation produced by AURION™ is reviewed and approved by Dr. Ethan Hausman-Marquis personally before it reaches you. It is not a quiz. It is not a template. It is a data-driven, physician-approved programme built from your individual biology.
Yes — without exception. No AURION™ supplementation programme is designed without comprehensive pre-consultation bloodwork reviewed personally by Dr. Ethan. This is non-negotiable. Supplementation without diagnostics is directional guesswork — you may be supplementing nutrients already in excess, missing deficiencies that actually exist, or introducing compounds that interact with medications you are taking. Mandatory diagnostics is one of the core principles that distinguishes The Catalyst Clinic from every other supplementation provider in this space.
The difference is fundamental. Personalised supplement quizzes and subscription services assign a stack based on your stated goals and lifestyle answers. AURION™ assigns a programme based on your actual bloodwork, reviewed by a physician with a PhD in Cell and Genomic Biology. One is a marketing exercise. The other is a clinical process. The recommendations that result are categorically different — and so are the outcomes for the patient.
Yes — monthly. Your supplementation programme is reviewed every month as part of your physician review, and updated in response to changes in your biomarker data, your advisory protocol, and your health profile. Bloodwork is repeated every four to five months, triggering a full programme reassessment. A supplementation programme designed six months ago may not be the right programme today. At The Catalyst Clinic, your programme is never static.
Yes — by design. Your AURION™ supplementation programme is not a separate service. It is an integrated extension of your advisory consultation, designed to work in concert with your advisory protocol compounds. AURION™ accounts for every compound in your programme when making supplementation recommendations — ensuring nothing conflicts, nothing is redundant, and everything is working towards the same biological goals.
Yes. Every AURION™ programme is personally reviewed and approved by Dr. Ethan Hausman-Marquis — PhD, Cell and Genomic Biology, Karolinska Institute — before it reaches the patient. No algorithm makes the final decision. No recommendation reaches you without Dr. Ethan's personal review and approval. This is the standard at The Catalyst Clinic and it does not change regardless of how many patients we see.
Yes. The Catalyst Clinic offers supplementation programmes as part of remote advisory consultations for patients across the UK, Europe, the UAE, Australia, Canada, and the United States. The clinical standard — mandatory diagnostics, personal physician review, AURION™ programme design, and ongoing monthly oversight — is identical for remote and in-person patients. To begin, book an initial consultation from £150 and Dr. Ethan will personally review your pre-consultation bloodwork before your appointment.
