What We Do

No More Guesswork.
No More Generic Vitamins.

At The Catalyst Clinic, we believe optimal health is not found on a shelf — it is built around you. Our Bespoke Supplementation Programme combines advanced diagnostics, clinical interpretation, and pharmaceutical-grade manufacturing to create a formulation designed specifically for your body's needs.

Every protocol begins with in-depth bloodwork and a comprehensive clinical review. Dr. Ethan analyses your biomarkers, lifestyle, medical history, medication interactions, and performance goals to identify deficiencies, imbalances, and opportunities for optimisation. Then he designs a precision supplement plan — formulated at therapeutic doses, refined every month as your data changes.

Whether your focus is energy, cognitive performance, hormonal balance, metabolic health, longevity, or recovery — your programme evolves as you do. This is supplementation redefined: strategic, data-driven, and built for measurable outcomes.

Proprietary Technology

AURION™️
The Intelligence Behind Your Formula.

AURION™️ is our proprietary AI formulation engine — the system that translates your bloodwork, medical history, current medications, lifestyle data, and clinical goals into a precision supplementation plan. It does not replace clinical judgement. It enables it — giving Dr. Ethan a complete biological picture before designing your formula.

AURION™️ integrates data points that standard supplement programmes never consider: nutrient competition, absorption pathway conflicts, medication interactions, circadian timing, and metabolic pathway dependencies. The result is a formulation that is genuinely yours — not a wellness archetype applied to your name.

What AURION™️ Analyses

01

Bloodwork & Biomarker Data

Full panel analysis — micronutrients, hormones, inflammatory markers, metabolic function, thyroid, liver, and kidney status — integrated into a single clinical picture.

02

Medication & Peptide Interactions

Screens for interactions between recommended supplements and any current medications or peptide advisory protocols — before formulation begins.

03

Absorption Pathway Optimisation

Identifies nutrient competition and absorption conflicts — structuring AM and PM formulations to eliminate negative interactions and maximise bioavailability.

04

Goals & Lifestyle Integration

Integrates performance goals, sleep patterns, stress levels, training load, and dietary data — ensuring your formula supports your life, not just your labs.

05

Continuous Refinement

Formula updates every month as your bloodwork evolves — maintaining precision over time, not just at the point of initial formulation.

The Process

Six Steps to Your
Precision Formulation

From your first consultation to your first delivery — every step is physician-led, data-driven, and built around your individual biology.

Step 01

Comprehensive Clinical Assessment

Every programme begins with a detailed medical evaluation — the clinical context from which your formulation is built.

  • Full medical and medication history
  • Lifestyle and performance review
  • Symptom mapping and health goal definition
  • Nutritional and environmental considerations
  • Peptide protocol interaction review

Step 02

Advanced Diagnostic Testing

Precision begins with measurable data. Testing is selected based on your clinical profile and goals.

  • Micronutrient profiling
  • Hormonal panels
  • Metabolic markers (glucose, lipids, insulin)
  • Inflammatory and oxidative stress markers
  • Gut health analysis
  • Functional and performance biomarkers

Step 03

Clinical Interpretation

Dr. Ethan interprets results within a systems-based medical framework — treating the whole person, not isolated numbers.

  • Endocrine, metabolic, neurological pathway analysis
  • Root cause prioritisation over symptom management
  • Identification of nutrient deficiencies vs insufficiencies
  • Medication interaction screening
  • Clinical return-on-investment prioritisation

Step 04

AURION™️ Precision Formulation

Once the clinical blueprint is clear, AURION™️ translates it into a bespoke formulation — produced at pharmaceutical grade in an EMA-regulated EU laboratory.

  • Individually dosed to laboratory values
  • High-bioavailability pharmaceutical-grade ingredients
  • AM and PM formulations to prevent nutrient competition
  • Free from unnecessary excipients and fillers
  • Manufactured to rigorous quality and purity standards

Step 05

Integration into Your Broader Programme

Supplementation sits within a wider optimisation strategy — designed to work synergistically, not in isolation.

  • Nutrition and dietary planning alignment
  • Sleep and circadian rhythm optimisation
  • Stress management protocol integration
  • Training and recovery alignment
  • Peptide advisory protocol coordination

Step 06

Ongoing Monitoring & Iteration

Biology evolves. So does your formulation. Monthly reviews and repeat biomarkers ensure your formula remains precisely calibrated.

  • Monthly symptom and performance review
  • Repeat biomarkers at appropriate intervals
  • Dose and ingredient adjustments
  • Formula refinement based on physiological response
  • AURION™️-driven continuous optimisation

Why It Matters

Supplementation Redefined.
Strategic. Data-Driven. Measurable.

The partnership between The Catalyst Clinic and AURION™️ allows us to combine clinical depth, diagnostic accuracy, pharmaceutical-grade production, and continuous optimisation into a single seamless programme. This is personalised medicine translated into personalised formulation.

01

Clinical Data — Not Assumptions

Your formulation is built from your actual laboratory values — not your age, gender, or a symptom questionnaire. Every ingredient and dose is traceable to a specific clinical finding in your bloodwork.

02

PhD-Level Design — Not Algorithms Alone

AURION™️ powers the data integration. Dr. Ethan Hausman-Marquis — PhD in Cell and Genomic Biology, Karolinska Institute — provides the clinical interpretation and final formulation decision. Always.

03

EMA-Regulated Manufacturing

Produced in an EMA-regulated EU laboratory to pharmaceutical-grade standards. Not a contract-manufactured generic stack with your name on the label. A genuinely bespoke formula built from scratch.

04

Medication & Peptide Interaction Screening

Before any formulation is finalised, AURION™️ screens for interactions between your supplements, any current medications, and any peptide advisory protocols you are on. Safety and synergy considered together.

05

It Evolves With You

Because AURION™️ supports adaptable manufacturing, your formula can change every month as your bloodwork changes — maintaining precision over time rather than locking you into a formula that was accurate six months ago.

06

Integrated With Your Whole Programme

Supplementation at The Catalyst Clinic is never standalone. It is designed as an integrated extension of your broader programme — coordinated with your peptide advisory protocols, nutrition plan, and training approach.

What It Covers

Built Around
Your Goals.

Your bespoke supplementation programme is designed around the specific health goals you bring to the consultation — and the biological data that confirms what your body actually needs to achieve them.

Formulations can be targeted across any or all of the following areas — based on your clinical findings, not on what you assume you need.

  • Energy production and mitochondrial function
  • Cognitive performance and mental clarity
  • Hormonal balance and endocrine support
  • Metabolic health and body composition
  • Longevity and biological age optimisation
  • Athletic performance and recovery
  • Sleep quality and circadian regulation
  • Immune function and resilience
  • Gut health and microbiome support
  • Skin health and collagen synthesis
  • Stress resilience and HPA axis support

The Result

Personalised Medicine
Translated into Personalised Formulation.

The outcome of the partnership between The Catalyst Clinic and AURION™️ is supplementation that is strategic, data-driven, and measurable — not generic, not trend-based, and never static.

Common Questions

Frequently Asked

Standard supplement programmes are built around demographics or symptom questionnaires. Ours is built from your actual laboratory bloodwork — analysed by a PhD-level physician and processed through AURION™️, our proprietary AI formulation engine. Every ingredient and every dose is traceable to a specific clinical finding in your data. The formula changes every month as your biology changes.
Yes, always. Comprehensive bloodwork is mandatory before any formulation begins. This is not optional — it is the clinical basis of the entire programme. Without your biomarker data, it is not possible to design a safe, personalised, or clinically appropriate supplementation plan. This standard is applied to every patient without exception.
AURION™️ is our proprietary AI-powered formulation engine. It integrates your bloodwork data, medical history, current medications, lifestyle information, and clinical goals to create a complete biological picture that Dr. Ethan uses to design your formula. AURION™️ does not replace clinical judgement — it supports it by ensuring no data point, interaction risk, or absorption conflict is missed.
All formulations are produced in an EMA-regulated EU laboratory to pharmaceutical-grade manufacturing standards. This ensures consistent purity, potency, and bioavailability — and means your formula is a genuinely bespoke product, not a generic supplement with your name on the label.
Yes — and this is precisely why medication and peptide interaction screening is built into every formulation process. Before your formula is finalised, AURION™️ screens for interactions between your recommended supplements and any current peptide advisory protocols, medications, or other compounds. Safety and synergy are considered together, not separately.
Your formula is reviewed every month and updated whenever your bloodwork or clinical picture changes. Because AURION™️ supports adaptable manufacturing, formulations can evolve continuously — maintaining precision over time rather than locking you into a static formula that may no longer reflect your biology.
Programmes start from £200 per month. This includes your bespoke AM and PM formulations, delivery, and monthly physician review. Pre-consultation bloodwork is required before your first formula and is arranged as part of your initial consultation with Dr. Ethan.
Yes. The Catalyst Clinic offers remote supplementation consultations for patients across the UK, Europe, the UAE, Australia, Canada, and the United States. Bloodwork can be arranged locally in most regions. The clinical standard — mandatory diagnostics, PhD-level design, monthly reviews — remains identical for all patients regardless of location.
