The Real Missing Piece

Work on the foundations and address the underlying nutritional and biochemical drivers

If you've spent more time than you care to think about cutting out sugar, trialling supplements, and following conflicting advice online- but still feel like you're guessing- you're not doing it wrong. You just haven't been able to be specific enough about the nutritional foundations needed for YOUR child. That missing piece is what makes everything else make sense.

I'm Ruth Fellowes, an ADHD nutritionist with 18 years of clinical experience helping Australian families understand the nutritional and biochemical drivers behind their child's behaviour, focus and mood and building a clear, personalised plan to address them.

Let's find out what your child's body is actually asking for. Every program below is designed to give you that clarity — and to meet you where you are right now.

Unsure and need help with deciding? Book a free 20min Strategy Call to get you started. 

Take the direct approach by looking at underlying drivers: nutrient levels, food intolerances, gut health, inflammation, toxicity.

Programs

Each program can stand alone or be used as a progressive pathway - from awareness and direction through to long-term mastery maintenance. Start with the step that makes sense for your family right now. 

Stage 1 | CLARITY

mini assessment

The What's Eating Your Child Audit

$47

one-off

Gain a quick overview of the internal biochemical drivers worsening child's mood, sleep, focus and behaviour.

Think of this as an online assessment to determine the key nutritional and biochemical factors influencing your child's development. You fill in a detailed symptoms checklist which I review and create a recorded video explaining exactly what I see, where the pressure points are, and what I'd do first. Clear direction on what to prioritise and the next step.

  • Gain clarity on the biochemical drivers impacting your child

  • No live appointment needed

  • Take the first step towards answers

Stage 2 | precision

8 week program

The Nourish + Grow Formula

$697
(or 2 x $360)

Find out exactly what nutrients your child's mind and body need more of.

Targeted lab testing (child friendly) combined with expert interpretation to uncover specific nutrient imbalances and developmental blocks.

You'll leave with a precise, evidence-based plan built around your child's actual results.

  • Especially valuable in the preschool years when early intervention makes the biggest difference

Stage 3 | MASTERY

12 wk + 12 wk support

The Restless to Calm Program

$1197
(or 6 x $249)

12 week program + additional 12 week online support

Gain a quick overview of the internal biochemical drivers worsening child's mood, sleep, focus and behaviour.

Lab testing to understand what is needed right now (nutrient testing), and in the long term (DNA testing) combined with guidance on making the long term changes in diet and sleep specific to your child.

Focus on gut health, fussy eating, inflammation and toxicity to help your child turn the corner with their mood, behaviour and health.

What families notice when we deal with the biological drivers

When we support the underlying nutritional and biochemical systems  rather than managing surface behaviours families typically report:

  • Calmer moods and significantly fewer meltdowns

  • Better sleep - falling asleep faster, staying asleep longer

  • Improved focus and engagement at school

  • Less aggression and defiance at home

  • More emotional resilience and self-regulation

  • A child who feels more settled in their own skin

These changes ripple outward. Daily life gets easier. Parents feel less reactive. And children begin to thrive,  not just manage.

Words of Thanks

"...the difference in him in the mental health realm is amazing. It's almost like it was a fog for him. when he does act out like all kids he has started to apologise and he is not as highly strung most days now. It has made everyone's lives so much lighter and happier."

"After years of following GP instructions, we have had the best results by actually looking at the underlying cause".

"She is far more active than before, which i think has also really helped improve her mood swings and tantrums".

"We lost him for 2 years but now he is the old H again! No more anger, rages, only childlike ones. Has control over his emotions. His humour has come back- that spark has come back"

FAQs

What if my child hasn't been formally diagnosed with ADHD- will nutritional medicine still help?

A diagnosis isn't required. Many families come to me because they can see something isn't right - difficult behaviour, poor sleep, emotional dysregulation, fragile focus - but haven't had (or aren't pursuing) a formal diagnosis. The nutritional and biochemical drivers I look at are relevant regardless of whether there's a label attached.

How is this different from seeing a GP or paediatrician?

A diagnosis isn't required. Many families come to me because they can see something isn't right - difficult behaviour, poor sleep, emotional dysregulation, fragile focus - but haven't had (or aren't pursuing) a formal diagnosis. The nutritional and biochemical drivers I look at are relevant regardless of whether there's a label attached.

Do you work with adults, or only children?

My clinical focus is children - particularly those with ADHD, difficult behaviour, mood dysregulation, and sleep challenges. If you're a parent wanting to better understand how your own biology is impacting on yourself, give me a call to see if I can be of help

Your child deserves to feel like themselves.
