Are you struggling with ongoing health symptoms but not getting clear answers?

Do you feel exhausted, inflamed, anxious, unable to sleep properly or unlike yourself?

Are you dealing with bloating, brain fog, stubborn weight gain, digestive issues, hormonal changes or ongoing symptoms despite being told your tests are “normal”?

Many chronic symptoms are interconnected and can be influenced by hormones, inflammation, gut health, blood sugar regulation, sleep, stress physiology, immune activity and overall metabolic health.

My approach focuses on understanding the wider picture of how the body is functioning through symptoms, health history, lifestyle, nutrition, blood work and functional assessment.

Nutrition plays an important role in energy production, metabolism, inflammation, hormone health, cognitive function and long-term wellbeing.

Areas commonly supported include:

• Fatigue and burnout

• Hormonal health including thyroid, peri-menopause, menopause and andropause

• Weight gain, insulin resistance and metabolic health

• IBS, bloating, reflux and digestive symptoms

• Anxiety, poor sleep and brain fog

• Histamine intolerance, MCAS and mould-related illness

• Joint pain and chronic inflammation

• Skin issues, recurrent UTIs and chronic symptoms

• Cognitive health and healthy ageing

• Cardiovascular and metabolic wellbeing

Every programme is personalised and built around the individual, their symptoms, lifestyle, health history and goals.

Advanced testing is available including hormone, gut health and metabolic testing.

Use nutrition, lifestyle analysis, blood work review and functional testing where appropriate to build a personalised and practical health strategy

Functional Laboratory Testing

These tests are designed to uncover root causes of fatigue, gut issues, hormone imbalance, brain fog, low mood, skin conditions, autoimmunity, and more. No GP referral is required, and most tests can be done easily from home using saliva, urine, stool, or finger-prick blood samples.

Core Functional Tests

Comprehensive Gut Health Panel

For IBS, bloating, constipation, fatigue, or skin issues
This test analyses microbiome balance, yeast and parasite overgrowth, gut inflammation, digestive enzyme output, and intestinal permeability.

Organic Acids Test (OAT)

For energy crashes, brain fog, mood swings, or detoxification issues
A deep metabolic analysis covering mitochondrial function, neurotransmitter metabolites, gut dysbiosis, and key nutrient pathways.

Adrenal and Cortisol Rhythm Test

For burnout, anxiety, or poor sleep
Assesses stress hormone patterns across the day to understand how the adrenal system is functioning and how it may be impacting mood, sleep, and energy.

DNA and Epigenetic Health Test

For personalised, preventative health planning
Analyses genes involved in detoxification, inflammation, methylation, nutrient needs, and ageing processes, with interpretation based on your current lifestyle.

Mycotoxin and Mould Exposure Test

For chronic fatigue, sinus issues, MCAS-type symptoms, or sensitivity to environments
Detects immune-reactive mould toxins that may be affecting mitochondrial and cognitive function.

Heavy Metal and Mineral Balance Panel

For neurological symptoms, fertility issues, or chronic fatigue
Assesses toxic load from mercury, lead, and aluminium, alongside essential minerals such as zinc, selenium, and magnesium.

Thyroid and Autoimmune Panels

For fatigue, anxiety, hair loss, weight gain, or cold intolerance
Comprehensive thyroid testing including T3, reverse T3, TPO antibodies, and Tg antibodies, which are not routinely tested on the NHS.

Blood Sugar and Insulin Resistance Panel

For cravings, energy dips, weight gain, or concerns around prediabetes
Functional assessment of fasting insulin, glucose, and HOMA-IR to detect early metabolic imbalance.

Functional Blood Interpretation

If you already have blood test results from your GP, I can interpret them through a functional lens
This allows us to spot patterns of dysfunction and nutrient depletion that may not yet meet diagnostic thresholds but still impact your health.

Specialist Panels Also Available

Food intolerance and histamine reactivity
Cardiovascular risk profiling including Lp(a), homocysteine, and hsCRP
Autoimmune reactivity and inflammatory markers
Glutathione status and oxidative stress
Environmental toxicant screening for plastics, pesticides, solvents, BPA, and phthalates
