Annette's Story: A Biochemistry-Led Approach to Long-Standing Depression

01 · The Situation

Decades of depression that had not responded to treatment

Annette, 62 and self-employed, was referred to the programme while receiving inpatient mental health care. She described a lifetime history of depression beginning in her early teens, and decades of treatment-resistant depression managed with antidepressant medication that had not resolved her symptoms.

In the weeks before intake she had experienced two hospital admissions. She described her energy as running on nervous energy, with sleep of around three hours a night. When asked what she hoped to achieve, her answer was to have joy in her life rather than continuing to fake her way through it.

02 · The Approach

A biochemistry-focused programme

This programme was delivered through functional pathology testing, targeted nutritional supplementation, dietary modification, and lifestyle adjustments. It did not include psychotherapy or counselling. Annette continued her existing prescribed medications throughout, under the care of her treating doctors.

Comprehensive testing

TestPurpose
Dried urine hormone panelHormone and cortisol mapping across the day
Comprehensive nutritional profileNutritional and metabolic assessment
Hair tissue mineral analysisMineral status, metabolic type, heavy metal exposure
Organic acids testingCellular metabolism, neurotransmitter metabolites, mycotoxins
Comprehensive GI panelGut microbiome analysis and inflammatory markers
Continuous glucose monitoringReal-time glucose stability assessment
Pharmacogenomic panelGenetic drug metabolism profile

What testing identified

Testing identified a number of findings that the naturopathic team considered relevant to Annette's presentation, including elevated metabolised cortisol suggesting the adrenal system was under sustained stress, low secretory IgA indicating compromised gut immune function, a metabolic pattern consistent with sluggish thyroid and adrenal function, elevated ammonia-producing gut microbes, and markers suggesting mould exposure.

Pharmacogenomic testing indicated she was a poor metaboliser on one enzyme pathway and an intermediate metaboliser on another — information relevant to how she processes certain medications, and shared with her treating practitioners.

A phased protocol

Phase 1 · Foundation

Mood support, omega-3 and fat-soluble vitamins, amino acid and mineral complex, and bone broth — focused on foundational nutrients and the gut-brain axis.

Phase 2 · Targeted Correction

Digestive enzymes, adrenal and thyroid support, zinc and copper rebalancing, vitamin C, and bioavailable iron.

Phase 3 · Metabolic Optimisation

Therapeutic B-complex and B1 repletion following further testing, alongside cardiovascular support.

Phase 4 · Detoxification Support

Liver and detoxification support as testing indicated the body was actively clearing accumulated heavy metals.

Dietary and lifestyle changes

Alongside supplementation, Annette introduced morning sunlight exposure to support her circadian rhythm, avoided corn following the mycotoxin findings, added daily bone broth and fermented foods, reduced evening blue light, and maintained daily walking.

03 · How Things Changed

Self-reported functional change

SleepAround 3 hours, interruptedRestful, waking refreshed
MoodAcutely unwell, recently hospitalisedDescribed as calm and stable
ActivityIn survival modeReturned to painting, writing, and language learning
AlcoholBinge patterns linked to depressive episodesReported months passing without drinking

Biochemical retesting over the same period showed her metabolic type shifting in a direction her practitioners interpreted as thyroid and adrenal function improving, with zinc and phosphorus levels rising, calcium normalising, and evidence of active detoxification.

These reflect one individual's reported experience, practitioner observations, and standardised assessment. Annette continued her prescribed psychiatric medications throughout under the care of her treating doctors. They illustrate a possible response to this type of programme and are not a guarantee of outcome for any other person.
04 · What May Have Supported Annette's Progress

Factors the care team identified

Annette's programme ran alongside her existing psychiatric care rather than in place of it, and change in a single case cannot be attributed to any one element. The naturopathic team identified the following as potentially significant.

Investigating biochemistry

Testing identified several imbalances — adrenal, thyroid, gut, and nutritional — that had not previously been explored, and which the team considered plausible contributors to her symptoms.

A phased, responsive protocol

Supplementation was adjusted over time in response to repeat testing rather than set once at the outset.

Dietary and lifestyle change

Sunlight exposure, sleep hygiene, dietary adjustments, and daily walking were sustained alongside the supplementation.

05 · Ongoing Care

Continuing to monitor

Annette continues with naturopathic support, and follow-up retesting is scheduled for late 2026 to monitor her biochemical markers over the longer term. She has remained under the care of her treating medical practitioners throughout.
