Personalised nutrition to get to the root of fatigue, hormone issues, digestive problems, inflammation, and more.

Functional nutrition support that’s evidence-based, clinically grounded, and tailored to real life.

 

Functional Nutrition & Root Cause Health Optimisation

 

Are you dealing with pain, inflammation, fatigue, brain fog, stubborn weight gain, or gut issues and not getting answers?

 

Perhaps you’ve been told everything looks “normal,” but you still don’t feel well. Whether you’re struggling with hormone imbalance (thyroid, menopause, andropause), autoimmune symptoms, skin conditions, or poor sleep, these issues are rarely random - they often point to deeper imbalances in the body’s systems.

 

If you’re tired of symptom suppression and want a deeper understanding of your health - I can help.

 

At Lauren Wallis Nutrition, I offer functional health assessments and personalised nutrition plans grounded in biochemistry, clinical insight, and ancestral principles. I help you uncover the why behind your symptoms - with practical, evidence-based strategies to restore balance.

 

With a background in nutritional biochemistry (BSc, University of Nottingham) and a Master’s in Medical Molecular Biology (MSc, University of Westminster), I’ve worked in life sciences and nutraceuticals for over 18 years. I’m a qualified nutritional therapist, IFM-accredited health coach, and FNTP-registered practitioner. My approach combines advanced testing (where needed), thorough assessment, and targeted support - so you can stop chasing symptoms and start building lasting health.

"Nutrition is a foundational tool - not just for symptom relief, but for restoring function, resilience, and long-term health from the inside out."

Areas I Commonly Support

I work with a wide range of complex, chronic, and unexplained symptoms - whether they’re new, or have been ongoing for years. My approach is functional, personalised, and focused on identifying what’s driving dysfunction beneath the surface.

 

Key areas include:

 

  • Hormonal health – including perimenopause, menopause, andropause, PMS, and adrenal dysfunction

  • Metabolic resilience and flexibility – supporting insulin resistance, thyroid health, stubborn weight gain, and fatigue

  • Digestive and gut issues – from IBS, bloating, reflux, and SIBO, to food reactions and leaky gut

  • Detoxification – supporting liver health, reducing toxic burden (e.g. heavy metals) and chemical sensitivity

  • Immune and inflammatory conditions – such as MCAS, mould-related illness, histamine intolerance, and chronic inflammation

  • Cognitive and emotional wellbeing – brain fog, low mood, poor focus, and disrupted sleep

  • Recurring conditions – including UTIs, candida, fibroids, skin issues, and viral reactivations

  • Ageing well – supporting cardiovascular health, cognition, longevity, and prostate health

 

I help you restore function across multiple systems - not by chasing symptoms, but by addressing the imbalances beneath them.

Your Health, Rebuilt From the Ground Up

I focus on clinical insight, symptom mapping, and functional assessment to create a clear plan - one that’s tailored to your biology and your priorities. I also offer advanced lab testing where appropriate, but the foundation of my work is food as medicine - combined with precise nutritional and lifestyle strategies that deliver sustainable change.

Take the First Step

Your health is your most valuable asset. When your body is in balance, you think more clearly, sleep more deeply, move with more ease, and feel more like yourself again.

Food as Medicine: The Power of Personalised Nutrition

Nutrition is more than just weight management—it’s the foundation of healing, metabolic balance, and long-term health. The foods you eat directly influence energy levels, digestion, hormone regulation, and immune function.

A functional nutrition approach goes beyond generic diet advice, identifying hidden imbalances that contribute to fatigue, stubborn weight gain, digestive distress, and inflammation. By understanding your body’s unique needs, we create a targeted nutrition strategy to restore balance and optimise well-being.

Functional Nutrition

A personalised approach can help:

 

  • Rebalance hormones and restore energy through targeted nutrition, thyroid support, adrenal work, and blood sugar regulation

  • Improve gut integrity, reduce bloating, and calm reactivity by restoring microbiome health

  • Enhance detox pathways and liver function to support resilience, skin health, and toxin clearance

  • Modulate immune activity and reduce chronic inflammation, especially in autoimmune, mould or histamine-driven conditions

  • Identify the drivers behind cravings, low mood, and emotional eating patterns by addressing stress physiology and neurotransmitter balance

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
