The Physical Side of Mental Health
The brain requires a continuous supply of specific nutrients, stable blood sugar, an intact gut-brain communication pathway, and balanced neurotransmitter production to function at its best. Poor gut function impairs serotonin, dopamine, and GABA production. Nutritional deficiencies directly impair neurotransmitter synthesis. Chronic inflammation crosses the blood-brain barrier and disrupts cognitive performance. These are measurable drivers with targeted solutions.
Cognitive and Mental Health Symptoms We Investigate
The following symptoms frequently have identifiable physiological drivers that functional testing reveals, including nutritional deficiencies, gut dysbiosis, HPA axis dysregulation, and neurotransmitter imbalances.
Cognitive Symptoms
- Difficulty concentrating and sustaining focus
- Short-term memory lapses and word-finding difficulty
- Mental fatigue after moderate cognitive effort
- Brain fog that is present most days regardless of sleep quality
- Declining performance at work or in tasks requiring sustained attention
- Early signs of cognitive decline including confusion and identity disorientation
Anxiety and Mood Symptoms
- Persistent anxiety disproportionate to circumstances
- Low mood, emotional flatness, or loss of motivation
- Irritability and mood swings without obvious cause
- Racing thoughts and difficulty switching off
- Mild to moderate depression that has not responded to standard intervention
Sleep and Energy Overlap
- Insomnia, difficulty falling or staying asleep
- Waking unrefreshed despite adequate hours
- Afternoon energy crashes accompanied by cognitive dullness
- Wired but tired in the evening, unable to wind down
- Night-time rumination and inability to quiet racing thoughts before sleep
- Disrupted sleep patterns linked to elevated evening cortisol
- Early morning waking with inability to return to sleep
Brain Function Optimisation Starts With the Right Investigation
Standard mental health assessment focuses on symptom severity and behavioural patterns. It does not routinely assess nutritional status, gut microbiome, cortisol rhythm, or inflammatory markers that directly influence brain function. That is the gap functional testing fills.
Neurotransmitter Imbalance
Serotonin, dopamine, GABA, and acetylcholine production depends on B6, B12, folate, zinc, and magnesium. When these nutrients are depleted or the gut produces excess disruptive metabolites, the entire signalling network is affected.
OAT neurotransmitter metabolites including serotonin, dopamine, and GABA precursor markers. Comprehensive nutrient panel for B6, B12, folate, zinc, and magnesium.
Gut-Brain Axis Disruption
Approximately 90% of serotonin is produced in the gut. When dysbiosis is present, bacterial metabolites enter circulation, trigger neuroinflammation, and alter neurotransmitter availability. Many clients with anxiety or poor concentration have significant gut dysbiosis on GI microbiome testing.

HPA Axis Dysregulation and Anxiety
Elevated evening cortisol disrupts sleep and impairs memory consolidation. Chronically low cortisol following adrenal depletion produces fatigue, anxiety, and inability to cope with ordinary stressors. Both patterns are invisible on standard blood tests.
AdrenoCortex salivary panel measuring four-point cortisol plus DHEA. Distinguishes elevated, depleted, and dysrhythmic patterns.
Nutritional Depletion
Magnesium deficiency impairs GABA receptor function, increasing anxiety. B12 deficiency causes cognitive slowing and mood instability before appearing as anaemia. Iron deficiency below functional threshold impairs dopamine synthesis and reduces mental drive.
Comprehensive nutrient panel covering B12, folate, ferritin, vitamin D, zinc, magnesium RBC, and omega-3 index.
Thyroid and Cognitive Function
Subclinical hypothyroidism and poor T4 to T3 conversion consistently produce cognitive slowing, poor memory, low mood, and anxiety, frequently missed because TSH remains within the standard reference range.
Comprehensive thyroid panel including TSH, free T4, free T3, reverse T3, TPO antibodies, and TgAb.
Toxic Load and Neuroinflammation
Environmental toxins, heavy metals, and mould-related compounds impair detoxification pathways and increase neuroinflammation. Clients with cognitive symptoms and no clear nutritional or gut driver frequently show elevated oxidative stress markers on the OAT.

Naturopathic Support for Anxiety in Melbourne
Anxiety is one of the most common presentations. It frequently coexists with gut dysbiosis, HPA axis dysregulation, nutritional depletion, and thyroid dysfunction. Treating anxiety without investigating these underlying drivers is one of the reasons many people cycle through interventions without lasting relief. Naturopathic support for anxiety at Vital Health begins with identifying which physiological pattern is driving the presentation. Anxiety driven by elevated cortisol and adrenal dysregulation requires a different protocol to anxiety driven by gut-derived neurotransmitter disruption or magnesium and B6 deficiency. Functional testing makes that distinction possible.
Anxiety Driven by HPA Axis Dysregulation
Elevated evening cortisol produces racing thoughts, hypervigilance, and disrupted sleep. Cortisol depletion following prolonged stress produces feeling overwhelmed by minor stressors and inability to cope with previously manageable demands.
Anxiety Driven by Gut Dysbiosis
Dysbiosis-driven neuroinflammation activates the vagus nerve and alters neurotransmitter availability. Many clients with anxiety have significant gut dysbiosis on GI microbiome testing, and addressing the gut frequently produces meaningful improvement.
Anxiety Driven by Nutritional Depletion
Magnesium is required for GABA receptor function, the primary inhibitory neurotransmitter that calms neural activity. B6 deficiency impairs serotonin synthesis. Zinc deficiency dysregulates the glutamate-GABA balance. All are common and correctable through targeted supplementation.
Mild to Moderate Depression
Gut-derived inflammation, HPA axis depletion, thyroid conversion dysfunction, and deficiencies in B12, folate, iron, and omega-3 fatty acids are the most consistently identified drivers. Naturopathic support works alongside, not instead of, psychological and psychiatric care where that is in place.
Functional Testing for Cognitive and Mental Health at Vital Health
Vital Health uses functional testing to investigate the physiological drivers of cognitive and mental health symptoms. Testing is matched to your specific presentation. Most clients require two to three tests.
Organic Acids Test (OAT)
At-home urine test measuring over 70 metabolites including neurotransmitter metabolites, mitochondrial function markers, nutritional adequacy, oxidative stress indicators, and gut dysbiosis markers. The primary test for cognitive and mental health presentations at Vital Health.
AdrenoCortex Salivary Panel
At-home saliva test measuring four-point cortisol rhythm plus DHEA. Essential for anxiety, mood instability, and sleep disruption. Identifies the specific HPA axis dysregulation pattern driving the presentation.
Complete GI Microbiome Map
At-home DNA stool test assessing gut microbiome balance, pathogen load, intestinal permeability, and inflammatory markers. Used when gut-brain axis disruption is suspected as a driver of anxiety, low mood, or cognitive symptoms.
Comprehensive Thyroid Panel
Blood test covering TSH, free T4, free T3, reverse T3, TPO and TgAb antibodies. Used when cognitive slowing or low mood accompanies fatigue or weight changes suggestive of thyroid involvement.
Comprehensive Nutrient Panel
Blood test covering B12, folate, ferritin, vitamin D, zinc, magnesium RBC, and fasting glucose and insulin. Identifies the nutritional depletions most commonly driving cognitive and mood symptoms.
How Domenic Approaches Cognitive and Mental Health
Cognitive and mental health symptoms rarely have a single cause. They typically involve gut dysfunction, nutritional depletion, HPA axis dysregulation, and thyroid involvement operating simultaneously. The ROOT Method is Domenic’s framework for working through these interconnected patterns systematically.
For cognitive health, restoring gut integrity first improves absorption of the nutrients needed for neurotransmitter production. Sequencing matters as much as the intervention itself.
Reveal
Identify specific physiological drivers through targeted functional testing.
Optimise
Address gut health, nutritional status, and HPA axis function in the correct sequence.
Orchestrate
Phase dietary, herbal, and lifestyle interventions so each stage builds progressively.
Track
Monitor neurotransmitter metabolites, nutrient levels, and clinical markers through retesting.
What Improvement Typically Looks Like
Cognitive and mental health improvements follow a specific sequence as physiological drivers are addressed.
Foundation Phase
Sleep quality typically improves first as cortisol rhythm stabilises and magnesium is restored. Irritability reduces and morning energy becomes more consistent.
Stabilisation
Anxiety frequency and intensity begin to reduce. Concentration improves. Most clients notice they are managing daily stressors with more capacity.
Deeper Improvement
Memory and cognitive clarity improve more consistently. Emotional resilience increases. For those with gut-driven symptoms, this is typically the window where gut and cognitive improvement align.
Sustained Progress
Sustained improvement becomes the baseline. Follow-up testing confirms whether neurotransmitter metabolites and nutritional markers have shifted and informs any protocol adjustments.

Frequently Asked Questions
Yes, as a complementary approach. At Vital Health, functional testing identifies the specific physiological pattern driving each client's anxiety, whether HPA axis dysregulation, gut dysbiosis, nutritional deficiency, or thyroid dysfunction, so the protocol addresses the cause rather than the label. Naturopathic support works alongside existing psychological or psychiatric care, including for clients seeking naturopathy for depression alongside conventional treatment.
Cognitive health refers to how well the brain processes information, retains memory, and maintains focus. Common drivers of decline include nutritional deficiencies, gut dysbiosis disrupting neurotransmitter production, chronic inflammation, HPA axis dysregulation, and thyroid dysfunction. These are identifiable through functional testing and addressable through targeted protocols.
Approximately 90% of serotonin is produced in the gut. When dysbiosis is present, bacterial metabolites drive neuroinflammation and alter neurotransmitter availability. Many clients with anxiety or low mood have significant gut dysbiosis on GI microbiome testing, and addressing the gut frequently produces meaningful improvement.
Mental health covers emotional well-being and psychological resilience. Cognitive health covers information processing, memory, and focus. The two are closely connected because depression and anxiety impair cognitive function, and declining cognition triggers emotional distress. Naturopathic care at Vital Health addresses both through the same functional testing framework.
Yes. Brain fog has measurable physiological drivers including gut dysbiosis, nutritional deficiencies, thyroid conversion dysfunction, and mitochondrial impairment. Where brain fog accompanies significant fatigue, it is frequently investigated alongside the chronic fatigue testing protocol as the two often share common drivers.
The initial consultation is 60 to 90 minutes covering symptoms, timeline, previous investigations, medications, diet, sleep, and stress load. Functional tests are recommended based on your specific presentation and results are reviewed in a dedicated consultation with a written protocol provided.
In most cases yes. Domenic reviews all current prescriptions before recommending any herbal intervention. The default approach is to support physiology through nutrition, gut health, and lifestyle before introducing herbal medicines, which minimises compatibility concerns.
Yes. All consultations are available via video call and test kits are delivered to your door anywhere in Australia. No referral is required to book.
Naturopathic support for cognitive decline focuses on identifying modifiable drivers including nutritional deficiencies, gut-driven neuroinflammation, mitochondrial dysfunction, and vascular risk factors. The goal is to reduce the physiological burden on the brain and support conditions most conducive to cognitive resilience. This is most effective when begun early, before significant decline has occurred.
