Mould & Mycotoxins

The learning framework

1
Why mould-related illness is commonly missed
Chronic mould exposure is increasingly recognised as a driver of fatigue, brain fog, hormonal disruption, respiratory issues, and persistent immune activation, yet it remains one of the most misunderstood and underdiagnosed triggers of chronic illness, with conventional care often missing the connection between water-damaged buildings, biotoxin burden, and multi-system dysfunction.
2
The gaps in practitioner assessment and training
Most practitioners lack training to identify mould-related illness, assess genetic susceptibility affecting biotoxin clearance, interpret functional markers of immune activation and detoxification impairment, or guide environmental remediation and recovery, leaving clients told their symptoms are psychosomatic while biotoxin exposure drives inflammation, mitochondrial dysfunction, and neurological symptoms.
3
A structured framework for environmental biotoxin recovery
The Mould module trains you to identify, assess, and support clients affected by environmental biotoxin load,understanding how mycotoxins trigger immune activation, mitochondrial stress, and systemic inflammation, and to build phase-based protocols that reduce exposure, support detoxification, and restore resilience.

What you'll learn

By the end of this module, you will be able to:
Understand the mechanisms of mould-related illness
Recognising how mycotoxins trigger immune activation, cytokine release, mitochondrial dysfunction, oxidative stress, and inflammatory signalling across brain, gut, hormones, and nervous system.
Identify clinical patterns suggestive of biotoxin burden
Recognising the constellation of symptoms that point to chronic mould exposure and CIRS.
Assess genetic susceptibility and detoxification capacity
Understanding HLA-DR gene variations that influence biotoxin clearance ability, explaining why some develop chronic illness from exposure while others do not.
Interpret functional markers of biotoxin illness
Using inflammatory markers, hormonal indicators, and immune activation patterns to assess biotoxin burden and systemic dysfunction.
Identify exposure sources and environmental risk factors
Recognising signs of water-damaged buildings, understanding when home testing is appropriate, and guiding environmental remediation or relocation decisions.
Apply targeted nutrition and detoxification protocols
Using binders, mitochondrial support, antioxidants, and anti-inflammatory strategies to support biotoxin clearance and reduce inflammation.
Build phased mould recovery protocols
Sequencing interventions through exposure elimination, binding and clearing biotoxins, restoring detoxification pathways, supporting mitochondrial function, and rebuilding immune resilience,operating within scope while recognising when specialist referral is needed.

Why this matters

The ability to solve cases others dismiss
Plus icon, svg, dark
Many clients with chronic, unexplained symptoms have undiagnosed mould exposure, and identifying this connection creates breakthrough results.
Confidence in complex, multi-system presentations

You'll assess immune activation, mitochondrial dysfunction, detoxification capacity, and environmental factors simultaneously.
Better client outcomes

Addressing biotoxin load often resolves fatigue, brain fog, hormonal issues, and autoimmune flares previously unresponsive to other interventions.
Professional differentiation

What does an Integrative Nutritional Therapist do?
Plus icon, svg, dark

An Integrative Nutritional Therapist utilises the latest evidence-based research to create an integrative approach to optimising each client’s health and wellbeing.

They design bio-individual nutrition plans, personalise supplementation where appropriate, and interpret functional laboratory data, including blood work, to gain deeper insights, achieve better accuracy and tailor every intervention to the individual.

How is functional medicine different from conventional medicine?
Plus icon, svg, dark

Conventional medicine often waits until a disease is clearly present before intervention begins. Treatment is focused on managing or suppressing a diagnosed condition.

Functional medicine looks upstream. It assesses the early drivers of dysfunction and works to prevent disease from developing in the first place, or restore balance in the body. It uses a whole-systems view of the body, then applies personalised, preventative nutrition and lifestyle interventions to support long-term health rather than only reacting once things have gone wrong.

What will be my scope of practice after completing this certification?
Plus icon, svg, dark

After completing the certification, you will be recognised and insured as a Integrative Nutritional Therapist inclusive of Nutritional Therapy and Functional Blood Work, with a clearly defined scope of practice.

You will be trained and insured to:

  • Design bio-individual nutrition plans
  • Recommend and prescribe over-the-counter supplementation up to safe, optimal intake thresholds
  • Utilise functional blood work from a wellness perspective to guide your reasoning and recommendations
  • Collaborate with and refer to medical professionals when red flags, pathology or out-of-scope conditions are identified

Our scope of practice has been aligned with nutritional therapy standards and externally audited, so you can work with confidence and clarity.

Is your course accredited?
Plus icon, svg, dark

Yes. Our certifications are accredited by multiple independent professional bodies, including the International Institute for Complementary Therapists (IICT) and the Complementary Medical Association (CMA).

To receive these accreditations, our curriculum undergoes forensic external auditing to ensure every component is up to date, evidence-informed, ethically delivered and aligned with recognised Nutritional Therapy and Functional Health standards. This includes rigorous evaluation of our academic content, assessments, delivery methods and scope of practice frameworks.

This external oversight gives you confidence that the qualification you are investing in is credible, robust and widely recognised within the industry, with clear pathways for insurance, professional membership and global practice.

Will I be able to practise internationally?
Plus icon, svg, dark

Yes. Our graduates are eligible for insurance through IICT that is recognised across 36 countries, including:

Australia, Austria, Belgium, Bulgaria, Canada, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, South Africa, Spain, Sweden & United Kingdom.

This allows you to work with clients internationally, including in online practice, provided you respect local regulations and the scope of practice defined by your insurer and professional associations.
