Expert functional nutrition — for people who are done guessing.
I’m Heidi Nowalany, Registered Naturopathic Nutritional Therapist and founder of The Milk Practice. I work with individuals, couples and families at every stage of life — from preconception through to adulthood.
Nine areas, one approach: find the pattern, start there.
I work with individuals, couples and families across every stage of life. Whatever has brought you here, my approach is the same — to investigate what’s really driving them and build a plan around you.
Most chronic health issues aren’t random. They’re a pattern.
My route into nutritional therapy wasn’t a straight line. A decade working at the intersection of infant feeding, airway and oral development gave me a clinical perspective that no textbook could — and showed me, again and again, that the answers are rarely where you’d expect them.
They’re rarely random — they’re a pattern. Finding the pattern is where I start.
How it works
1
Get in touch
We start with a conversation about what’s going on for you and whether we’re a good fit.
2
Full case history
I take a thorough, unhurried look at your complete health picture.
3
Your plan
You receive a personalised plan built around your life, not a generic protocol.
I’m Heidi Nowalany — Registered Naturopathic Nutritional Therapist, IBCLC and LifeCode Gx practitioner. I work with individuals and families to investigate the deeper drivers of health, using functional testing, nutrigenomics and a genuinely personalised approach.
If you’ve tried the elimination diets, the supplements — and still don’t feel right — you’re in the right place.
The full story first — not just what’s in front of me.
My journey
I began my career as an International Board Certified Lactation Consultant, supporting families through many complex feeding challenges. Over a decade, I saw something that fascinated me — how often feeding difficulties, airway issues and oral development pointed to deeper patterns in the body.
That curiosity led me to train as a Registered Naturopathic Nutritional Therapist at the College of Naturopathic Medicine, so I could investigate those deeper patterns properly. Today I work with individuals, couples and families across every stage of life.
My approach
Every client begins with a thorough, unhurried review of their complete health history — how you’ve been feeling, diet, lifestyle, environment and the full timeline of how things developed. From there, I build a personalised plan.
The plan is only as complex as it needs to be. My job is to find what matters most and start there. Change that sticks is change that fits your life — not a protocol that requires your life to fit around it.
What makes my approach different
A decade working at the cutting edge of infant oral function and airway gave me an unexpected window into the deeper workings of the body. I understand, in a way few nutritional therapists do, how breathing, the airway and the nervous system shape long-term health.

How I work
A partnership — a proper investigation, not a quick fix.
Working with me is a partnership — a proper investigation into your health, not a quick fix or a generic plan. Here’s what to expect.
01
No pressure · No script
It starts with a conversation
Before anything else, we talk. Get in touch and we’ll arrange a short, no-pressure conversation about what’s going on for you, what you’ve already tried, and whether we’re the right fit to work together. There’s no obligation and no script — just an honest discussion.
02
Unhurried · In depth
A thorough case history
If we decide to work together, we begin with a full case history. This is an unhurried, in-depth look at your complete health picture — your diet, lifestyle, sleep, stress, environment and the full timeline of how things developed. Most people have never been asked these questions in this much detail before.
This is where the investigation begins. Most persistent problems aren’t random — they’re a pattern. My job is to find it.
03
Only when it changes the plan
Functional testing, where it helps
Where it’s clinically useful, I use functional testing to see what’s actually happening inside your body rather than guessing. Depending on your situation this might include organic acids testing, comprehensive stool analysis, hormone profiling, mycotoxin screening or blood chemistry.
I arrange any testing for you and interpret the results in detail — so you understand not just what they show, but what they mean for you. Testing is never done for its own sake; only when it will genuinely change the plan.
04
Built around your life
Your personalised plan
From everything I learn, I build a plan that’s yours alone. It brings together nutrition, targeted supplementation, lifestyle medicine and, where relevant, breathwork and nervous system support.
The plan is only as complex as it needs to be. I won’t overwhelm you with thirty changes at once. We find what matters most and start there — because change that sticks is change that fits your life.
05
Foundations first
A phased approach
Meaningful change happens in stages. We typically begin by laying foundations — stabilising symptoms and removing the biggest stressors. From there we move into more targeted support, refining the plan based on how your body responds. For longer programmes, we finish by consolidating progress and preparing you to continue confidently on your own.
06
LifeCode Gx
Nutrigenomics — precision nutrition
For clients who want the most tailored approach possible, I offer nutrigenomic testing through LifeCode Gx. This looks at how your unique genetic profile influences the way your body processes nutrients — so your plan can be built for you specifically, not for the average person.
07
6 weeks to 6 months
How long it takes
Every person is different. Some start with Starter for a single concern and a clear plan to follow. Others, particularly with complex or long-standing concerns, work with me over three to six months so we can investigate properly and adjust as we go. We’ll find the right level of support for you when we first speak.
Nine areas, one approach: find the pattern, start there.
I work with individuals, couples and families across every stage of life. Whatever has brought you here, my approach is the same — to investigate what’s really driving your symptoms and build a plan around you. Select any area to read more.
01
Pre & Post Conception
Preparing your body for pregnancy, and rebuilding it afterwards — nutrition for fertility, pregnancy and recovery.
+ Read more
The months before conception matter more than most people realise — for both partners. I support couples preparing for pregnancy with targeted nutrition to optimise fertility and lay strong foundations for a healthy pregnancy.
After birth, I help mothers replenish what pregnancy and birth deplete, supporting recovery from the inside out.
Bloating, discomfort, irregular digestion, food reactions, skin issues — these are some of the most common reasons people come to me, and some of the most rewarding to investigate.
Using detailed case history and, where helpful, comprehensive stool analysis, I look beyond the surface to find what’s actually driving them.
03
Maternal & Postnatal Nutrition
Replenishing what pregnancy and feeding deplete — targeted nutrition for new and recovering mothers.
+ Read more
Pregnancy and feeding draw heavily on a mother’s nutrient reserves, and the postnatal period is often when depletion catches up. Exhaustion, low mood, hair loss, poor recovery — these are common but they are not something you simply have to accept.
I provide targeted nutritional support to help you rebuild and feel like yourself again.
04
Child & Toddler Nutrition
Fussy eating, growth, immunity and gut health — helping your child thrive from the inside out.
+ Read more
From fussy eating and faltering growth to recurrent illness, eczema and digestive troubles, children’s health questions are rarely simple.
I support families with practical, evidence-based nutrition that works in real life — helping your child thrive without turning mealtimes into a battleground.
05
Airway & Breathing Health
How you breathe affects far more than you think — from sleep and energy to long-term chronic health.
+ Read more
How you breathe affects far more than you might think — your sleep, your energy, your focus, and your long-term health. Drawing on a decade of clinical work with airway and oral function, I help clients understand and address breathing patterns that may be quietly undermining their wellbeing.
Working with your body’s natural clock to restore energy, sleep and metabolic health.
+ Read more
Your body runs on an internal clock that governs sleep, hormones, metabolism and mood. When that rhythm is disrupted — by stress, light, shift work or modern life — the effects ripple through your whole system.
I help clients work with their natural rhythm rather than against it, to restore energy and proper, restorative sleep.
07
Men’s Health & Nutrition
Energy, metabolic health, stress resilience and longevity — nutrition tailored to men at every stage.
+ Read more
Men’s health is too often overlooked. Whether it’s energy, metabolic health, weight, stress resilience or longevity, I provide nutrition tailored to men at every stage of life — grounded in proper investigation rather than generic advice.
08
Mould & Environmental Health
When your environment is making you unwell — identifying and addressing hidden environmental triggers.
+ Read more
Sometimes the thing making you unwell is your environment. Mould and other environmental exposures can drive a wide range of stubborn, hard-to-explain health issues that don’t respond to conventional approaches.
I help clients identify and address these hidden triggers, using specialist testing where appropriate.
09
Nutrigenomic Testing
Precision nutrition tailored to your unique biology — using your genetic profile to build a plan made for you.
+ Read more
I use genetic testing to understand how your unique DNA influences the way your body processes nutrients — so your nutrition plan is built for you specifically, not for the average person.
As a LifeCode Gx certified practitioner, I translate your genetic profile into precise, personalised recommendations. This is precision nutrition: less guesswork, more clarity.

How you breathe shapes your health in ways most people never consider.
An unexpected window. I spent a decade working at the cutting edge of infant feeding, airway and oral development. It gave me an unexpected window into the deeper workings of the body — and showed me how something as fundamental as breathing connects to so much of our long-term health.
It’s a connection I now bring to all of my work, with clients of every age.
Why breathing matters more than you think. Breathing isn’t just about getting air in and out. The way we breathe — through the nose or the mouth, deeply or shallowly, by day and especially by night — influences how well our tissues are oxygenated, how our nervous system is regulated, and how our bodies recover and repair.
When breathing is dysfunctional, the effects rarely stay in one place. They ripple outwards, often quietly, over years.
The cascade. Disordered breathing can set off a chain of consequences throughout the body. Compromised airways and poor breathing patterns can reduce oxygen delivery and disrupt the production of nitric oxide — a molecule central to circulation, immune function and far more. Over time, this cascade has been linked to a wide range of chronic conditions.
What it connects to
Sleep quality and sleep disorders
Autoimmune and thyroid conditions
Cardiovascular and metabolic health
Inflammatory conditions
Energy, focus and mental health
The mouth and the microbiome
The story begins even higher up — in the mouth. Oral health, the oral microbiome and how the mouth and airway develop all play a part in how we breathe and, in turn, how we thrive. This is the territory I worked in for years, and it informs how I see the whole picture.
How I work with this
In practice, this means I look at breathing as part of your wider health picture — alongside nutrition, sleep, stress and environment. Where it’s relevant, I draw on breathwork and nervous system techniques from my yoga training, and from September 2026, the Buteyko Method, to help clients restore healthier patterns.
Alongside my functional nutrition practice, I am the founder of The Milk Practice — my specialist infant feeding and lactation consultancy, established in 2017.
Est. 2017 · IBCLC
Two practices, one practitioner.
As an International Board Certified Lactation Consultant, I have supported over 1,200 families through every kind of feeding journey — from breastfeeding and tongue tie to reflux, oral function and introducing solids.
It was this work that first opened my eyes to how deeply connected feeding, airway and whole-body health really are — and ultimately led me to train as a nutritional therapist.
The Milk Practice focuses on babies and infant feeding. My nutrition practice, here, works with individuals, couples and families at every stage of life. The two are separate — but they share the same investigative approach and the same commitment to looking beyond the obvious.
I see clients in person in Fulham, SW London, and virtually worldwide. Wherever you are, we can work together.
What happens next
When you get in touch, we’ll arrange a short conversation to talk through what’s going on for you and whether we’re the right fit. There’s no pressure and no obligation — just an honest discussion about how I might be able to help.
