I help high-achieving women who are tired of feeling burnt out overwhelmed and unlike themselves. Using functional testing, we look beneath the symptoms to understand what may be driving your brain fog, anxiety or lack of focus – so you can think clearly, feel better and feel like yourself again.

Hello, I’m Karoline!
I’m here for you. Maybe you’ve spent more nights than you’d like to admit falling down a neuro-divergent Google rabbit hole, trying to piece together what’s actually going on. Maybe you’ve been told your bloods are “normal,” but you don’t feel normal at all.
You can’t switch off at night or wake up at 3am with your mind racing. You snap at the people you love over things that shouldn’t matter. You’re wired but exhausted and you can’t focus on work or in life. Maybe you’re crying more easily, or maybe you’ve gone numb.
Whatever it looks like for you, it’s real, and there’s a reason – most likely more than one – behind it. Functional testing helps us find what it is.
My methodology helps us look further upstream than symptoms alone can show us. Instead of chasing what’s on the surface, we look at what’s actually happening in your hormones, your gut, your detox system and your stress response, the dysfunction underneath.
My role isn’t to hand you a quick fix. It’s to help restore function, balance and resilience to your body, so it can do what it’s innately capable of doing.
Imagine waking up feeling rested. Not dragging yourself through the first two hours on caffeine, just awake, clear, ready for the day.
Imagine your weight starting to shift, not because you’re eating less or pushing harder at the gym, but because your body is finally getting what it needs to regulate itself.
Imagine feeling like yourself again. Not a medicated version, overwhelmed and barely recognisable. Yourself.
That’s what becomes possible when we stop managing symptoms and start addressing what’s behind them.

As a certified Functional Diagnostic Nutrition Practitioner, I bring specialised training in functional lab testing, so you get answers instead of guesswork.

Every plan is built around your unique biological lab results and health story, and an understanding of your mental and emotional wellbeing.

Using the FDN methodology, I help you break the cycle of trial and error, by looking past symptom management toward change your body can actually sustain.
My path here started with my daughter. Toddler acne showed up before her third birthday, and changing her diet cleared it completely. I thought that was the end of it, until it came back the moment she hit puberty at 10.
That’s when I turned to functional lab testing, and it showed things the specialists never looked at: gut permeability, food sensitivities an irregular hormone cycle. Working with an FDN practitioner, I watched real, lasting change happen for her, not by treating what was on the surface, but by understanding what her body was actually dealing with underneath.
That same principle is what I bring to my work with women now. Anxiety, low mood, brain fog and overwhelm are signals too. My job is to help you understand what they’re pointing to.
I believe your body wants to heal and knows how, once we have removed the obstacles getting in the way. Symptoms aren’t random, they’re information, and my job is to help you make sense of these messages instead of just managing them.
I believe in testing instead of guessing, so we’re working with your real biology rather than a generic checklist. That means looking at what’s actually happening with your body’s systems – hormones, immune, digestion, detoxification, stress response- and not assuming.
I believe you deserve a plan built around you, not a protocol you can get off the internet. Our coaching sessions involve working together to implement small, sustainable changes, with the right information that fits your life and adds up to real and lasting change.

How it works
1.
We start with a free 45-minute conversation. You share what’s been going on, I explain how I work, and we figure out together whether this is the right fit. It’s a real conversation, not a sales call. You’ll leave with clarity either way.
2.
If we move forward, we start with a detailed health history and order your functional lab panel. Most tests are done at home with a collection kit sent directly to you. No clinic visit required.
3.
Once your results are back, we go through them together in a dedicated session. You’ll understand exactly what we found, why each part of your protocol is there, and what we’re working toward.
4.
We meet regularly throughout your program to track progress and adjust as needed. A recommended second lab panel mid-program shows us what’s shifting so we’re always working from current data.
My Programs

30 DAYS
A starting point that allows us to include the most essential lab test paired with lifestyle assessments to identify what’s driving your health challenges.

3-6 MONTHS
Core program if you want comprehensive answers to your main health complaint, and a clear actionable plan to get you back on track to feeling like you again.

12 MONTHS
This is for you if you’ve been living with health challenges for a long time. Deep Dive gives us more time and the option to test further, to understand what else might be going on.

Most are completed at home. You’ll receive a collection kit, complete the sample yourself (saliva, urine, stool, blood draw or finger stick depending on the panel), and ship it to the lab. Results come back to me, and we review everything in a dedicated session.
Programs run from 30 days to 12 months depending on how long you’ve been dealing with your health issue. My goal is always to get you to a point where you don’t need me anymore, with the option to move onto a lighter maintenance plan for ongoing support after that.
Functional lab testing and health coaching are typically not covered by insurance. Think of this as an investment in getting actual answers rather than more managed care.
No. Many clients come to me having only had standard bloodwork, or none at all. We start wherever you are. If you’ve had testing done before, that’s helpful context, but it’s not a requirement.
I don’t treat the paper. Meaning, I don’t base your plan on test results alone. It’s personalised, evidence-based and focused on understanding your body rather than just managing symptoms.
That’s the most common story I hear. It usually means the approaches weren’t matched to what was actually happening in your body. Starting from your data rather than a general protocol tends to produce a very different experience.
That’s not a barrier. Many clients I work with are already on medication for anxiety, or working with a therapist or psychiatrist, and still feel there’s more going on. We work alongside your current care, and what we find can also be useful information to share with your other providers.
We start with a complimentary 45-minute call to understand your health goal and see if we’re a good fit. If after this call you decide you’d like to work with me, I will order your functional tests and build your plan around what the results show and your comprehensive health history.
