People ask for help for many reasons. Mostly though we reach out and humbly ask because we just don’t know what we need to know so as to move forward. Getting informed breaks the hold of fear, doubt and lethargy.

Hartmut Gunther

Science, experience,
and genuine curiosity

Born in Germany and based in Tasmania, I bring an unusual combination of molecular science, clinical nutrition, and human psychology to health practice — a range that allows me to address not just what is happening in the body, but why, and what a person is actually ready and able to do about it.

I currently teach and design health programmes at a residential drug and alcohol rehabilitation centre, consult for a national corporate health company, and am the founder and CEO of Toxtest — an Australian environmental analysis laboratory operating through Southern Cross University, NATA certified.

I also write — for Innerfood on Substack and for Travel for Health — because making complex health information genuinely accessible to real people is something I care deeply about.

There are real benefits by engaging with life’s learnings and inner experiences. Equally, our misplaced openness to others’ dramas, our tendency to blame and revenge, worrying about what others think of me, being ruled or influenced, albeit subtly or unconsciously, by fear, causes us unnecessary dis-stress. We then get to see what works and what doesn’t.

Four ways I can help —
and how you benefit

Each area draws on the same foundation: rigorous science, decades of clinical experience, and a genuine desire to help you understand and act on your own health.

01 — Clinical Consulting

Health & Nutrition Consultations

Individual consultations addressing root causes, not just symptoms. Biochemistry, clinical nutrition, and psychology working together — including blood test interpretation, gut health, hormones, weight, and addiction support.

You leave with clarity, a plan, and the confidence to work effectively with your own health team.

02 — Environmental Testing

Toxtest Laboratory Analysis

Australia's dedicated environmental and biological analysis service. Testing water, soil, dust, food, hair (human and animal), and supplements for heavy metals, PFAS, pesticides, and more. NATA certified through Southern Cross University.

You know exactly what you're exposed to — and what you can do about it. Knowledge replaces fear.

03 — Clinical Trial of One

Listen to Your Body. Document It. Decide.

Health decisions grounded in your own data. It begins with learning to truly listen to your body — noticing, paying attention, documenting what you observe. That observation becomes data. Data, paired with objective measurements, becomes evidence you can act on.

You move from guesswork to clarity, and from passivity to genuine ownership of your health outcomes.

04 — Education

Health Education for Individuals & Groups

Classes, presentations, one-on-one mentoring, and written resources. Topics include how to talk to your doctor effectively, how to understand your own pathology results, and how to use AI responsibly as a health research tool.

You develop lasting health literacy — the confidence and skills to navigate your health independently, for life.

Real benefits — in your own words

Even a short engagement brings you back into contact and focus with what matters. It re-acquaints you with all that is good and powerful within you.

Better Health Outcomes & Clearer Priorities

Driven by sustainable micro habits — enjoying being physical, eating what is right for you, stopping fights with sleep, moving forward and understanding. Standing on your own two feet, empowered, especially if you need to interface with the medical profession or health professionals.

More Brain Power and Energy

Greater clarity, less pain, more joy, less addiction, better work performance, more insights and realisations. Getting to the core of what is driving your fatigue — and doing something about it.

Cost Savings — Now and Later

Early investment minimises big expenses later in life. Invest in learning and quality food and you are rewarded with the wealth of health. Spending now on prevention costs far less than spending later on illness.

The Upward Spiral

As the positive synergistic effects of the nine doctors kick in, the quality of life feels like it is on an upward trajectory. It doesn't matter how old or young you are, man or woman, rich or poor — the playground of life is levelled when we commit to all nine.

The Nine Doctors

Also known as: The Non-Negotiables of Life

The original meaning of Doctor is teacher — docēre, to instruct, to show. Each of the Nine Doctors is something you already have access to. Together, they form the non-negotiable foundation of a healthy and meaningful life. Small, sustainable habits practised with each of them compound quickly — and noticeably.

Agency & Growth
Act now. Thinking and planning are not doing. Don't put off till tomorrow what can be done today.

Willpower is overrated. Developing micro habits and sustainable systems is key.
I help you design micro habits that actually stick — and systems that run quietly in the background.
Movement
Exercise and strength, which fuels agility and becomes more important and rewarding as we age. Movement is integral to existence — find what you love and build from there.
I help assess the right movement for your body, age, and any specific conditions.
Nutrition
Nourishes trillions of cells so they can do their work. Knowledge of food preparation and organisation is essential. Eating well is one of life's genuine pleasures.
I provide personalised nutritional assessments — not generic diets, but practical guidance specific to you.
Hydration
Lubricates, transports nutrients in and waste out. Facilitates cellular communication at every level. The quality of your water matters as much as the quantity.
Toxtest offers affordable water quality testing for your home, school, or workplace.
Sleep
No longer rocket science. Prioritise at least 8 hours and tune into your own needs. Sleep deprivation cascades through every other Doctor — it is the foundation everything else rests on.
I help identify the biochemical and behavioural contributors to poor or disrupted sleep.
Work & Meaning
A gift and a challenge. Work enables resources. Meaning provides Joie de Vivre — the joy of life. Doing the right thing challenges us and facilitates growth so we don't stagnate.
Sometimes our work changes. It's useful to talk to someone or be guided through this transition period. Here to help.
Learning, Novel Experience & Travel
To survive, thrive and enjoy life, we need to keep learning. It's important to learn things we are passionate about and enjoy. Novel experiences — particularly in the form of travel — can rekindle the desire to discover something new.
I write about this at Travel for Health and Innerfood.
Kindness & Contact
A superpower that genuinely changes lives for the better. Connection with family, friends, or other living beings is not optional — it is physiologically and psychologically essential.
Often overlooked in clinical settings. I take it seriously in every consultation.
Self-Knowledge
Knowing thyself — that includes the good, the bad, and the divine. That is what gives us the feeling of a life well spent.
Psychology and behaviour training helps inform this dimension, as does the knowledge and practice of going within. Hartmut has 45 years experience in this domain.
The Tenth Doctor — Your GP & Health Team
Your medical team when needed — essential and valued. I help you get organised before appointments, articulate your symptoms clearly, and make those interactions as productive and non-frustrating as possible. Better conversations with your doctor lead to better outcomes for you.

Each moment is fragile and fleeting. The moment of the past cannot be kept, however beautiful. The moment of the present cannot be held, however enjoyable. The moment of the future cannot be caught, no matter how desirable. But the mind is desperate to fix the river in place: possessed by ideas of the past, preoccupied with images of the future, and lacking in any training or introduction to Knowledge of the Self. It overlooks the plain truth, the reality, the exquisite aliveness of the moment. And suffering prevails.

The deepest experience of one’s inner self has the ability to act like a calming balm to the mind and gives it permission, if you will, to completely let go. In that state all is forgiven, all is set right, clarity emerges and renewed energy to embrace the day prevails.

Clinical Trial
of One

A Clinical Trial of One begins not with a spreadsheet — but with truly listening to your own body. Noticing. Paying attention to what changes, what hurts, what improves, and when. That observation, once documented, becomes data. And data, paired with objective measurements, becomes evidence you can genuinely act on.

Rather than relying on population-level averages, this methodology gathers your specific baseline, tests a defined intervention, and measures what changes. It is particularly valuable when the evidence is nuanced, individual variation matters, and decisions involve weighing real benefits against real-life impact.

The Four Phases
1
Baseline — Comprehensive Data Gathering
Fact and data gathering before any intervention:
  • Blood work
  • Symptoms — documented using the LQQTSA framework
  • Lifestyle and activity patterns
  • Body composition
This is what we compare everything against — so we can see clearly what works and what doesn't.
2
Defined Intervention
One deliberate, measurable change — a supplement, exercise protocol, dietary shift, or medication withdrawal. One variable at a time, clearly defined before we begin.
3
Follow-Up Testing
Repeat the same measurements after a defined period. What changed, what didn't. The data does the talking — not assumptions or guesswork.
4
Informed Decision
Armed with before-and-after data, decisions move from guesswork to evidence.
Always shared with your GP or specialist for collaborative next steps.

Motivation often increases after you begin. The lesson is not to wish you had more motivation, but to make starting as easy as possible.

After a lifetime of blaming others, it is exceedingly difficult for us to finally acknowledge that the only person who has consistently been in all the scenes of that long-running soap opera we call our life is us — and that we bear some large responsibility for how the drama is turning out.

Learning more will increase knowledge, but only attempting more will reduce fear. The more you try it, the less you will fear it.

What clients say

I had really come to the end of the line. I was on a downward spiral. Medications, poor diet, couldn't think straight. The assessment and resulting interventions helped turn things around for me.

Working Mother — Queensland

Thank you for your diligent follow-up and your networking with the chef and Mum's doctor. She seems very satisfied that she has been heard. I am extremely grateful for the way you have advocated for Mum.
