The Problem

You’ve Tried to Do the Right Things

But Your Body Still Feels Stuck

Here’s Why…

You’re treating symptoms, not systems

You may have changed your diet, tried supplements, or followed medical advice but the gut, hormones, and nervous system are deeply connected. When they’re addressed separately, progress stalls.

Your nervous system is overloaded

Chronic stress, life demands, and past experiences keep your body in survival mode. When this happens, digestion, hormones, sleep, mood, and energy can’t regulate properly no matter how hard you try.

There’s no clear, supportive path forward

You’ve been given pieces of information, but not a clear order or framework. Without structure, healing feels confusing, overwhelming, or impossible to sustain.

THE SOLUTION

You don’t need to try harder.

You need a calm, structured approach that supports your whole system together.

I work with the gut, hormones, and nervous system as one integrated foundation, so your body can finally feel safe enough to respond.

Kirstie Vesseur

I’m Kirstie Vesseur, a Registered Clinical Nutritionist supporting women with complex gut, hormone, and nervous system concerns who feel unheard, overwhelmed, and stuck despite doing “all the right things.”

My work focuses on understanding patterns rather than chasing symptoms, and on supporting the body in a way that is calm, structured, and sustainable.

Over the past decade, I’ve worked with women navigating perimenopause, PMS and PMDD, digestive dysfunction, chronic stress, and nervous system overload often after being told their tests are normal or their symptoms are “just part of life.”

I specialise in cases where progress has stalled, symptoms feel interconnected, and standard approaches haven’t gone far enough.

My approach integrates functional nutrition, nutrigenomics, and nervous-system–informed care to support the gut, hormones, and stress response together because lasting change doesn’t come from doing more, but from doing the right things in the right order.

The Healing Journey

The Clinical Case Assessment is the first step in working together. This session allows us to understand your full health picture including symptoms, history, nervous system load, nutrition, labs, and current capacity.
The purpose is to determine whether a functional, nutrigenomics-informed approach is appropriate and what level of care your body requires.
Based on your assessment, a clear clinical pathway is recommended. This may include a short-term stabilisation programme, longer-term comprehensive care, or preconception support depending on your presentation and goals.
Functional testing and nutrigenomic insight are used selectively when clinically indicated. These tools help identify underlying drivers rather than guessing or escalating interventions prematurely.
Care is delivered in the correct clinical sequence, prioritising nervous system regulation, physiological safety, and tolerance. Plans are adjusted as your body responds, with education and support provided throughout.

Supporting Women With Hormone, Gut and Genetic Health Concerns

Practical, non judgemental women’s health nutrition support

My work is designed to meet you where you are, not where you think you should be. Every plan is personalised around your symptoms, your biology, and your capacity. There is no value in a perfect protocol if it does not fit your life.

I work one on one with women through structured three and six month clinical nutrition journeys, supporting hormone balance, gut health, nervous system regulation, and metabolic health. We look at symptoms, lifestyle patterns, blood work, and genetics to build a plan that makes sense and can be sustained.

This is not about doing more. It is about doing the right things, in the right order.

Whether you are seeking fertility nutrition support, exploring the hormone gut connection, or wanting DNA informed nutrition, this is evidence informed care that works with your body, not against it.
