Focus on ADHD and neurochemical balance

When your mind never quiets down — and no one asks why.

Data-driven coaching for adults with ADHD or suspected ADHD: focus, energy, micronutrients and hormones, looked at together.

„You're just stressed." „You're probably just exhausted." „Sounds like burnout." Many adults hear these sentences for years before anyone asks whether it might be ADHD. Women in particular are recognised late. Some only see the pattern in themselves after their child gets a diagnosis. If you recognise yourself in any of this, it pays to take a closer look at your focus, your energy and your biochemical foundation. If you're looking for coaching for adults with ADHD in Switzerland or anywhere across Europe, this is the work I do.

Important context: I'm a PhD scientist and coach (not a medical doctor). I don't diagnose ADHD and I don't prescribe medication. My coaching complements medical care and works on the lifestyle levers that support your focus and well-being.

Three situations where ADHD coaching makes a real difference.

Late-diagnosed ADHD in women

You were the kid teachers described as a daydreamer. The grades were still fine. Today, you're exhausted no matter how much you sleep. You put off things you actually know how to do. Emotions blindside you out of nowhere. You spend twice the energy others do just to get through the day. Maybe your child has just received an ADHD diagnosis, and suddenly a lot of what you never understood about yourself starts to make sense. That's a familiar pattern. It's worth taking seriously.

ADHD gets louder in perimenopause

For years, you've kept your ADHD in check. Then, somewhere between 35 and your early forties, the wheels come off. Focus, gone. Mood, all over the place. A kind of exhaustion you've never felt before. What's rarely talked about: estrogen supports dopamine function. When estrogen fluctuates and falls during perimenopause, the ADHD that used to be quiet suddenly becomes loud.

The diagnosis is there, the medication isn't enough

You have the diagnosis. The medication helps, but not the same way every day. Sometimes the effects fluctuate, sometimes the side effects weigh on you, and often you sense: something underneath isn't right. Iron too low. Sleep restless. Blood sugar on a rollercoaster. That's exactly where coaching steps in — alongside what your physician prescribes.

ADHD isn't a willpower issue or a character flaw. It's biochemistry — and biochemistry is something you can understand and support.
More than focus

Five biological systems that shape how loud your ADHD feels.

ADHD often gets reduced to „a dopamine deficit". In reality, several biological systems work together, all of them influencing how much dopamine and noradrenaline are available. That, in turn, shapes how clearly you can think, how much energy you have, and how steady your mood is. Turning only one screw means missing the rest of the levers.

The gut-brain axis

Your gut and your brain are in constant conversation — through the vagus nerve, the microbiome and inflammatory messengers. About 90 percent of your serotonin is made in the gut, and certain bacteria also influence dopamine precursors and your stress response. What this often explains: brain fog, mood swings, focus that drops out mid-task, broken sleep, that „tired but wired" feeling.

Iron and ferritin

No iron, no dopamine. Iron is a core building block for dopamine synthesis. Studies show that many adults with ADHD have strikingly low ferritin, even when the GP calls it „within range". For the brain, the optimum tends to sit above 50–80 ng/ml — not at the lab's lower cutoff of 15. What this often explains: tiredness despite sleep, a low stress threshold, restless legs, scattered focus especially in the afternoon.

Blood sugar and insulin

The ADHD brain is especially sensitive to blood sugar swings. The post-lunch energy crash, the afternoon sugar cravings, the irritability when the next meal is late — all of it points to an unstable glucose curve. Steady this, and focus becomes much more reliable. What this often explains: focus falling apart after a meal, hangry mornings, sugar cravings in the late afternoon, attention that yo-yos throughout the day.

Thyroid and estrogen

Estrogen supports dopamine and serotonin. When it fluctuates and falls during perimenopause, ADHD often becomes much more noticeable in women. A thyroid in the grey zone amplifies the picture too, by slowing the metabolism and dropping energy production. What this often explains: ADHD that suddenly gets much louder in your late thirties, focus dips in the second half of the cycle, exhaustion despite thyroid markers that the lab calls „normal".

Sleep and the HPA axis

ADHD brains are unusually likely to have a shifted sleep rhythm and a sensitive stress response. A flat or inverted daily cortisol curve — too low in the morning, too high in the evening — makes almost every ADHD symptom louder: trouble falling asleep, trouble waking up, that „tired but wired" feeling in the evening, emotions that flood in without warning. Steadying sleep is often the single strongest lever we have in coaching. What this often explains: chronic undersleep despite real fatigue, only becoming productive late at night, waking up foggy after eight hours.

Important: An ADHD diagnosis and, if needed, medical treatment belong to your physician. In coaching, we work on the lifestyle levers that support your focus, your energy and your well-being — micronutrients, sleep, blood sugar, gut, movement. That complements an existing or future medical treatment; it doesn't replace it.

My path to this work

Why the biochemistry behind focus and energy has held my attention for years.

My own path into functional medicine started with gut issues and chronic exhaustion in childhood. One thing I understood early on: focus, energy and emotional steadiness aren't a question of character. They are the output of a finely tuned biochemical machinery — one that tips when iron, B12, magnesium, omega-3 or sleep are missing, when the gut is out of balance, when hormones go off-script.

The deeper I went into the research, the clearer it became how often what gets labelled „burnout" or „depression" is in fact a mix of undiagnosed ADHD, depleted micronutrient stores and shifting hormones. Especially in women who managed to compensate for their ADHD for decades — until perimenopause pulls the curtain back.

I work with adults who have ADHD, or suspect they might, and who sense that there's more to their exhaustion than „just stress". Many of them have heard for years: „You just need to be more structured." That rarely holds. What more often holds: no one has actually looked at their biochemical foundation in any real depth.

My coaching is for people who sense that their brain works differently — and who want a data-driven way to finally take the lifestyle side of their ADHD seriously.

„ADHD isn't a parenting failure, it isn't a character flaw, and it isn't burnout. It's a biochemical reality — and that's precisely why there's so much you can move biochemically, alongside what medicine can do."

My approach

Inspired by functional medicine: ADHD in its full biological context.

ADHD support doesn't end with a diagnosis and a prescription. If you really want to move forward, you need both — the medical side and the biochemical, everyday foundation that holds everything else up. That's exactly where my coaching steps in.

Step 1

Preparation and history-taking

Before we meet for the first time, I go through your existing lab results and your ADHD history, if you have one. That way I can ask targeted questions in our session instead of losing time on the basics. In the conversation itself, I take the time for your full story: focus, sleep, energy, mood patterns, how you handle stress, what you eat, family history, earlier diagnoses.

Step 2

Deeper context and test suggestions

After the history session, I review your results and your story in depth. Where important markers are missing, we work out together which tests could bring clarity — ferritin, active B12, vitamin D, magnesium in whole blood, zinc, omega-3 index, an extended thyroid panel, fasting insulin and HbA1c, possibly a daily cortisol profile. The tests themselves are ordered through your GP, your psychiatrist or a specialised lab. I help you ask the right questions.

Step 3

The full picture and a prioritised plan

Once the additional results are in, I place them carefully within the full picture — together with your symptoms and your daily life. From that, we develop a prioritised plan that supports your focus, energy and stress resilience: nutrition with an eye on blood sugar and micronutrients, exercise as a dopamine booster, sleep strategies, stress regulation, micronutrient guidance. Specific medication and ADHD treatment itself stay with your physician or psychotherapist — I give you the understanding to talk with them as an equal.

Step 4

Step-by-step support

Nobody has to change everything at once, and that matters even more for ADHD brains. We work through the plan at your pace, reflecting, adjusting, going deeper. After three to four months, a second round of markers is often worth it so you can objectively see what has shifted — in your results and in your daily life.

Markers in coaching

Which biomarkers we review together.

With ADHD, it pays to look at markers that directly connect to dopamine and noradrenaline, energy production and neural function. Which ones you actually request from your physician or a specialised lab is something we work out together.

Micronutrients and neural co-factors

  • Ferritin and transferrin saturation: iron status — critical for dopamine synthesis. The functional optimum is often well above the lab's lower cutoff.
  • Active B12 (holo-TC) and methylmalonic acid: more meaningful than total B12.
  • Folate (active as 5-MTHF): central to methylation and dopamine pathways.
  • Magnesium in whole blood and zinc: both co-factors for neurotransmitter synthesis.
  • Vitamin D: influences dopamine receptor expression and mood.
  • Omega-3 index: several studies link it to ADHD symptom load.

Metabolism, hormones, inflammation

  • TSH, free T3, free T4, reverse T3: the full thyroid picture, not just TSH.
  • Fasting insulin, HbA1c, HOMA-IR: insulin sensitivity and glucose stability — a direct focus marker.
  • Daily cortisol profile (saliva, 4 time points): HPA axis and sleep-wake control.
  • Estrogen and progesterone (for women from their mid-thirties): essential to dopamine function.
  • hsCRP: silent inflammation that can amplify neuroinflammation and symptoms.
  • Homocysteine: a signal for methylation themes and B-vitamin status.

Which markers matter most in your case depends on your story, your life phase and your symptoms. We discuss that in the free consultation, and in coaching we prioritise together.

FAQ

Frequently asked questions about adult ADHD coaching

How is ADHD coaching different from psychiatric ADHD treatment?

A specialist psychiatrist or psychotherapist diagnoses ADHD, prescribes medication where appropriate, and provides psychotherapy. My coaching complements that. I work with you on the lifestyle side: micronutrients, sleep, blood sugar, movement, daily structures, self-awareness. That doesn't replace a diagnosis or a medical treatment plan.

How do you recognise late-diagnosed ADHD in adults, especially in women?

ADHD in adult women often goes unnoticed for years because many girls present the quiet, daydreaming subtype and compensate well at school. Typical adult signs are chronic exhaustion despite enough sleep, procrastination despite real talent, emotional flooding, sensory overwhelm, time-blindness, rejection sensitive dysphoria (RSD), and a noticeable worsening during perimenopause. An ADHD diagnosis is made by a specialist physician or psychotherapist — I can help you find the right places to start that process in Switzerland or across Europe.

Does perimenopause make my ADHD symptoms worse?

Very often, yes. Estrogen supports dopamine and serotonin function. When estrogen fluctuates and then drops during perimenopause, the dopamine availability that's already reduced in ADHD becomes even more noticeable. Many women report that their symptoms get sharply louder somewhere between their late thirties and early forties. This is where it pays to look at estrogen, thyroid, the HPA axis and your micronutrients alongside the ADHD picture.

Which markers are useful to look at with ADHD?

In coaching we look together at markers that connect to dopamine and noradrenaline availability, energy production and neural function: ferritin and iron (ferritin ideally above 50–80 ng/ml), vitamin B12 and folate (ideally in active forms), vitamin D, magnesium in whole blood (intracellular), zinc, omega-3 index, thyroid markers (TSH, free T3, free T4), hsCRP for silent inflammation, fasting insulin and HbA1c for glucose stability. Which markers make sense in your case is something we work out together. Tests are ordered through your physician.

What does my gut have to do with my focus?

A great deal. About 90 percent of your serotonin is produced in the gut, and the gut-brain axis communicates with your brain through the vagus nerve, the microbiome and inflammatory messengers — directly shaping your mood, focus and sleep. In ADHD, dopamine availability is naturally reduced. A leaky gut barrier or a microbiome out of balance can make that picture worse. Many people with ADHD benefit from looking at the gut in parallel.

Do micronutrients really matter in ADHD?

The research is clear here: iron, zinc, magnesium, vitamin B6, omega-3 fatty acids and active B-vitamins are co-factors for dopamine and noradrenaline synthesis and for neural function. Studies show that micronutrient gaps can significantly amplify ADHD symptoms. That doesn't make medication unnecessary, but it can make medication work better and reduce side effects. Specific supplements are discussed individually and, where needed, coordinated with your physician.

I'm already on ADHD medication — does coaching still make sense?

Yes, often even more so. Many clients come in with an existing prescription and notice that the medication's effectiveness fluctuates, or that the side effects are tiring. That's exactly where coaching works: stable blood sugar, enough iron and the right micronutrients, sleep quality, stress regulation — all of that can support the medication. The medication itself stays in your physician's hands, nothing is changed without their knowledge.

How does the coaching work online?

The coaching takes place entirely online via video call. All you need is a stable internet connection. I work with clients across Switzerland, Germany and Austria. Tests can be ordered through your GP, your psychiatrist or a specialised lab in your country — a recommendation of what's accessible where you live is part of the coaching.

Does health insurance cover the cost?

Some Swiss supplementary health insurances such as SWICA or CSS contribute to health coaching. It's worth asking your insurer specifically. The coaching packages themselves are billed directly with me. The cost of laboratory tests is partly on you, depending on the test and your insurance — we discuss this transparently before you order anything.

How long does it take before something shifts?

First changes — steadier energy, calmer sleep, less of the afternoon crash, clearer focus — are often noticeable within the first four to eight weeks, when the right lifestyle levers are pulled. Building up iron or vitamin D stores typically takes three to six months. Nothing is guaranteed; it depends on where you're starting from. But most clients notice a real difference once the biochemical foundation is in place.
