A six-pillar clinical framework for gut health, hormone regulation, and nervous system recovery

The Legacy Method is a structured, evidence-based clinical nutrition framework designed to support women with complex gut, hormone, and nervous system symptoms.

This method is led by Kirstie Vesseur, Registered Clinical Nutritionist, with advanced training in precision health through the Academy for Precision Health founded by Dr Denise Furness. Kirstie is also an HPN graduate and a mentor to the Holistic Performance Institute, supporting developing practitioners working with complex clinical presentations.

A root-cause approach to women’s health

Many women arrive at this work after years of managing symptoms rather than understanding them. Blood tests may appear “normal”, yet the body continues to signal distress through fatigue, digestive issues, hormonal disruption, mood changes, and reduced resilience.

The Legacy Method does not treat symptoms in isolation.

Instead, it examines how stress physiology, digestion, hormones, nutrient status, genetics, and daily lifestyle patterns interact to create ongoing dysfunction. This systems-based view allows care to be delivered with clarity, precision, and respect for the body’s capacity.

Delivered in the correct clinical sequence

Care within The Legacy Method follows a deliberate clinical order.

Regulation and physiological safety are prioritised first. A dysregulated nervous system directly impairs digestion, hormone signalling, blood sugar control, and the body’s ability to tolerate intervention. Once regulation is established, deeper gut, hormone, and metabolic work can be introduced with far greater effectiveness and sustainability.

This sequencing reduces flare-ups, improves tolerance, and supports lasting change.

The six pillars of The Legacy Method

Pillar 1. Nervous system regulation

Restoring physiological safety and stress resilience. This pillar forms the foundation of all work, as nervous system dysregulation influences digestion, hormones, inflammation, and symptom reactivity.

Pillar 2. Gut health, immune function, and inflammatory load

Supporting digestion, absorption, microbiome balance, gut lining integrity, immune activation, and elimination in a way the body can tolerate without triggering symptom flare-ups.

Pillar 3. Hormones and cycle biology

Addressing cortisol rhythm, insulin sensitivity, thyroid signalling, and sex hormone balance, with attention to menstrual cycle patterns and life stage transitions.

Pillar 4. Nutrient status and biochemical foundations

Identifying and repleting key nutrients required for detoxification, neurotransmitter function, hormone metabolism, and cellular energy, based on individual needs and capacity.

Pillar 5. Genetics and nutrigenomics

Using genetic insight where appropriate to understand individual differences in stress response, inflammation, detoxification pathways, and nutrient requirements, allowing for more personalised care.

Pillar 6. Integration, advocacy, and long-term sustainability

Embedding changes into real life so improvements are sustainable, resilient, and compatible with work, motherhood, and ongoing stressors. This pillar supports long-term capacity rather than short-term fixes.

A framework designed for women who need depth and clarity

The Legacy Method is particularly suited to women with persistent or complex symptoms, those navigating hormonal transitions, or those who have felt medically dismissed and are seeking a more integrated approach.

Functional testing and nutrigenomic analysis are used selectively and thoughtfully where appropriate, not as a prerequisite to care. Consultations are delivered online, with testing available globally.

This is clinical nutrition designed to work with the body, not against it.
