WELLNESS
Welcome to my page. The N in N-health stands for my name, Natasja, but also for Nature and Nurture. Essential for us as humans.
Health isn't a coincidence. It's the result of understanding biology, consciously choosing a lifestyle, and providing the body with the right conditions to recover and thrive. It also involves building awareness so the brain knows what needs to be done. In my practice, prevention is key: optimizing energy, cognitive acuity, hormonal balance, stress regulation, and metabolic flexibility before symptoms arise.
Science means that every intervention is rooted in current insights from clinical psychoneuroimmunology, epigenetics, and metabolic medicine. Health means looking at the whole: brain, immune system, hormones, mitochondria, gut microbiome, and environment as a single, integrated network. Wellness means vitality, clarity, resilience, and a body that not only functions but performs.
For those seeking more than just symptom management, I offer a comprehensive program that combines prevention, optimization, and recovery. Whether it's about longevity and performance, or specialized support for cancer, metabolic syndrome, Long COVID, or trauma-related dysregulation, the principle remains the same: strengthening the individual, regulating the system, and building sustainable health.
For those who consciously want to optimize their health, but also for those who have already traveled a long way with conventional and/or complementary care without finding a lasting answer, I offer a different approach. It's not focused on treating isolated symptoms, but on restoring underlying regulation. Where systems are out of balance, the key often lies.
Whether it concerns preventive vitality, or guidance for cancer, metabolic syndrome, Long COVID or trauma-related dysregulation: the core remains the same.
Empowering humanity. Regulating the system. Building sustainable health. Investing in your health is investing in freedom. In the energy to create, lead, and live at the highest level.
You are very welcome!

What exactly is kPNI or Orthomolecular?
Ook wel nutritionele, functionele of integrale geneeskunde genoemd. Orthomoleculaire geneeskunde is een benadering die werkt met stoffen en interventies die het lichaam van nature herkent en gebruikt: voedingsstoffen, leefstijlinterventies en gerichte ondersteuning van biochemische processen. In plaats van het onderdrukken van symptomen, ligt de nadruk op het optimaliseren van fysiologische functies. Leefstijl vormt de basis. Voeding is daarbij een essentieel uitgangspunt, omdat voedingsstoffen op celniveau en moleculair niveau directe invloed hebben op enzymen, receptoren, mitochondriën (de energiecentrales van de cel), hormonen en immuunreacties. Wanneer er langdurig tekorten bestaan aan essentiële voedingsstoffen, kan gerichte suppletie tijdelijk nodig zijn om biochemische processen weer op gang te brengen. Orthomoleculaire geneeskunde beperkt zich echter niet tot voeding en supplementen. Advies over gedrag, beweging, slaap, stressregulatie en herstelmomenten maakt integraal deel uit van de begeleiding. Het doel is het creëren van optimale omstandigheden waarin het lichaam zijn zelfherstellend vermogen kan benutten. Binnen het huidige zorglandschap wordt orthomoleculaire geneeskunde vaak onder de complementaire geneeskunde geplaatst. In de praktijk kan zij in veel gevallen aanvullend worden ingezet naast reguliere behandelingen. kPNI is wetenschappelijk PNI staat voor Psycho-Neuro-Immunologie. De k voor klinisch of de c voor clinical. Deze discipline onderzoekt de wisselwerking tussen psyche (gedachten en emoties), het zenuwstelsel (onder andere neurotransmitters), het hormonale systeem en het immuunsysteem (zoals cytokinen en barrièrefuncties). De klinische toepassing hiervan wordt klinische PNI genoemd. kPNI is gebaseerd op moderne biomedische wetenschap en verbindt kennis uit onder meer immunologie, endocrinologie, neurologie, metabole geneeskunde en evolutionaire biologie. Het wordt daarom ook wel een metadiscipline genoemd: een verbindende wetenschap die verschillende specialisaties samenbrengt. Waar in de reguliere geneeskunde vaak per orgaan of specialisme wordt gekeken, richt kPNI zich op de onderlinge samenhang tussen systemen. Gedachten beïnvloeden hormonen. Hormonen beïnvloeden het immuunsysteem. Het immuunsysteem beïnvloedt de hersenen. Lichaam en geest zijn biologisch onlosmakelijk met elkaar verbonden. Verschillende zienswijzen De reguliere geneeskunde is onmisbaar, vooral binnen acute zorg, chirurgie, infectieziekten en levensbedreigende situaties. Zij werkt veelal via een gerichte interventiestrategie: medicatie, bestraling of chirurgie om een acuut probleem te behandelen. De orthomoleculaire en kPNI-benadering richt zich vooral op het herstellen van verstoorde regulatiemechanismen die vaak ten grondslag liggen aan chronische klachten. In plaats van het symptoom centraal te stellen, wordt gezocht naar de onderliggende ontregeling in energiehuishouding, ontstekingsbalans, darmbarrière, hormonale regulatie of stressas. Het symptoom is zelden het werkelijke beginpunt van het probleem. Het is meestal het zichtbare gevolg van een dieper liggend proces. Evolutie als fundament De mens is gevormd door miljoenen jaren evolutie. Onze genen, stofwisseling, stressrespons en immuunsysteem zijn afgestemd op omstandigheden die sterk verschillen van onze huidige leefomgeving. kPNI gebruikt evolutionaire biologie als referentiekader om te begrijpen waarom bepaalde moderne leefstijlfactoren kunnen bijdragen aan chronische ontregeling. Zonder kennis van onze biologische oorsprong is het moeilijk te begrijpen waarom ons lichaam reageert zoals het reageert. Energie als kern Een centraal concept binnen zowel orthomoleculaire geneeskunde als PNI is energie. Energieproductie in de mitochondriën bepaalt in grote mate de functionele capaciteit van weefsels. Wanneer de energieverdeling in het lichaam verstoord raakt, kunnen organen en systemen minder goed functioneren. Chronische klachten gaan vaak gepaard met een verstoorde energiebalans. Herstel begint daarom vaak bij het optimaliseren van de energiehuishouding. Voeding als biochemische sturing Voeding beïnvloedt alle systemen in het lichaam: het immuunsysteem, de hersenen, de hormonen, de darmbarrière en de energieproductie. Daarom wordt binnen kPNI gebruikgemaakt van inzichten uit de orthomoleculaire geneeskunde om gerichte voedingsinterventies in te zetten. Intermittent living Een belangrijk concept binnen kPNI is intermittent living: het gecontroleerd blootstellen aan korte, gezonde prikkels zoals koude, warmte, vasten of intensieve inspanning. Het moderne leven is comfortabel en constant. Juist het ontbreken van acute, kortdurende stressprikkels kan leiden tot verminderde adaptatie. Het lichaam heeft variatie nodig om veerkrachtig te blijven. Deep learning – inzicht Tijdens consulten wordt veel aandacht besteed aan uitleg. Door middel van duidelijke schema’s en tekeningen wordt inzicht gegeven in hoe systemen werken, hoe ze ontregeld raken en hoe herstel mogelijk is. Begrijpen wat er gebeurt in het lichaam vergroot motivatie, zelfregie en duurzame gedragsverandering. De echte oorzaak Binnen consulten staat het opsporen van verstoorde werkingsmechanismen centraal. Niet alleen welk orgaan klachten geeft, maar welk regulatiesysteem uit balans is geraakt. Wanneer deze onderliggende ontregeling wordt aangepakt, kan langdurige symptoombehandeling vaak worden verminderd of zelfs overbodig worden. Behandeling richt zich op het herstellen van regulatie via voeding, leefstijl, gerichte suppletie, inzicht en cognitieve herstructurering. Het doel is niet afhankelijkheid van zorg, maar herstel van zelfregulatie. Heeft u vragen of wilt u bespreken wat deze benadering voor uw situatie kan betekenen? Neem gerust contact met mij op. Ik heb de vernieuwde versie van de kPNI opleiding genoten, de 4 jarige SNRO HBO NVAO geaccrediteerde versie, er bestaan ook 2 jarige of Belgische versies, of andere landen
Why should you work with me on your health, and not with someone else? Perhaps the most honest answer is: feel what feels right for you. Health is personal. Trust is too. Yet there is more. You are welcome with a request for help regarding prevention, but just as much with existing complaints or illness. My focus is not on suppressing symptoms, but on understanding the underlying regulation. I explain what is happening, in plain language, so that your brain understands what is needed and the body regains the space to tap into its self-healing capacity. Also, if you currently have no complaints, for example, I look at your lifestyle and choices, and the mechanisms as they are currently operating. Together with you, I can look at what choices your body might start making as the path continues, or if you start making adjustments here and there. I view complaints as signals: a system trying to communicate. Prevention is better, but if they are present, we can look at them together and also work on preventing them. Together, we investigate where those signals truly originate and what is needed to restore balance. Even when you come with a diagnosis, I look beyond the label. I map out connections between the brain, immune system, hormones, gut, nervous system, and metabolism. Which patterns reinforce each other, and in which direction does the system move if processes remain unconscious? Health is dynamic. What seems small today can be a guiding force tomorrow. By making those lines visible in a timely manner, space is created to make adjustments. I work systemically, using a scientifically grounded approach within functional medicine and clinical psycho-neuro-immunology. This means that we do not view the body in separate parts, but as one coherent network in which the brain, immune system, hormones, mitochondria (the cell's energy factories), gut microbiome, and living environment continuously communicate with each other. My approach goes beyond orthomolecular therapy alone. In a comprehensive intake (Deep Dive), I map out your health via timelines: not just a snapshot, but the story behind it. Step by step, the common thread becomes visible, allowing us to work back to the root cause of the complaint. From there, a personal plan emerges. Not a standard protocol, but a tailored approach, with follow-up and guidance. Consultations can take place online or at the practice. Ultimately, health revolves around energy: how well your system can produce, utilize, and regulate energy. When that energy balance falters, symptoms arise. When energy becomes available again, space for recovery is created. My goal is to empower you. With as few consultations as possible, but with maximum clarity and insight. After each consultation, you will receive a detailed advice letter with a plan of action, so that you understand why we do what we do. The most important thing is that you feel at ease. That we work together on your best version, on multiple levels simultaneously. We start at the basics, with real depth. Mouth and gut health. The mouth forms the beginning of the digestive system. Disruptions in the oral flora can affect gut health and the immune system. Therefore, the entire process, from mouth to gut, is always examined before working on restoring gut health. Metabolism and healthy weight loss. When metabolism functions well, the body can regulate energy better, and weight loss can occur naturally. Cancer and prevention. In my practice, we look at how the body can be supported as effectively as possible, both preventively and during periods when recovery and regulation are particularly important. Long COVID and chronic diseases. When the immune system and energy balance are under prolonged pressure, the body can become unbalanced. By examining the underlying systems, space for recovery is often created. In addition to these areas of focus, I also guide people who want to optimize their health. People who want to experience more energy, think clearly, and support their bodies to age healthily. Health is no accident. It is the result of understanding what the body needs and consciously making room for it.

QUESTION QUARTER
15 minutes of expertise, clarity without a process. Sometimes a full treatment plan isn't necessary. Sometimes you just need direction. The Q&A session at N-Health® is a short, powerful 15-minute consultation where you can ask one specific health question. No extensive intake. No mandatory follow-up. Even if you're not already a client. You can be completely new. Who is this suitable for? For individuals who: – Want to better understand a specific complaint, question, or insight, whether curative or preventative – Are unsure about a result or advice (this can also be obtained from someone else as a second opinion) – Want to know if a more extensive process or intake is useful – Want quick professional insight so they can move forward independently, as a kind of support along the way For professionals who: – Want to discuss a case of their clients – Want to delve deeper into a complex client of their own – Need medical or comprehensive support – Want to strengthen their own practice with substantive sparring This consultation is also suitable if you run a salon, practice, or healthcare business and need a scientifically substantiated perspective on a client's question. What can you expect? In 15 minutes, you will receive: • A sharp analysis of your question • Explanation based on neuro-immunological and metabolic connections • Concrete direction or next steps • Clarity about what is and isn't necessary No standard answers. No superficial reactions. But concentrated expertise. Personalized and often fully reimbursed for individuals with supplementary health insurance (more information further down this website) Why this works Many health questions don't immediately require a long-term process. Sometimes it's enough to: – recognize patterns – correct an incorrect assumption – identify a missing factor – or simply gain reassurance The Q&A session is intended as a professional compass. A moment of alignment. A short but valuable benchmark. And can be booked as often as desired. Practical Duration: 15 minutes Format: online For whom: new and existing clients, individuals and professionals Schedule directly via the online calendar.
EXTENDED INTAKE
EXTENDED INTAKE FOR CANCER
An In-Depth Intake into your health. Not a superficial conversation — but a turning point. The in-depth intake at N-Health® isn't a standard initial consultation. It's a Deep Dive session. A carefully structured moment where we reflect together on your current situation, exactly as it is. No rush. No standard protocol. With room for nuance. I don't just look at symptoms. I explore mechanisms. What might be functioning differently than desired in the interaction between the brain, immune system, hormones, metabolism, and nervous system? Where is regulation disrupted? What patterns are visible? And perhaps even more importantly: why? During this comprehensive session, I will explore the following: – underlying biological mechanisms – hormonal and immunological regulation – neuropsychological patterns – metabolic processes – mental and emotional burden – lifestyle and environmental influences – potential risk factors in the present – past influences, trauma, toxicity, and the like – transgenerational burden, if applicable – factors that are no longer active but still have an effect Health develops in a coherent manner. And so does disruption. That's why we don't just look at "what's wrong," but at the larger system in which your body functions. From current situation to desired direction Together, we outline: • where you are now • the underlying dynamics • which factors hinder recovery • and what a desired situation might look like From there, a personalized treatment plan is developed that is realistic, strategic, and well-founded. No individual recommendations. No standard protocols. But a comprehensive course of action. Including preparation, analysis, and follow-up The investment in this intake encompasses more than just the consultation time. You will receive comprehensive intake forms beforehand, which will be carefully analyzed and interpreted, along with any laboratory or blood results you share. During an in-person consultation, an additional test will also be performed to assess how cell production functions at the body's cellular level. This provides valuable information about your mitochondrial capacity and energy regulation. (This test is, of course, not possible with online consultations.) Afterward, you will always receive: – a comprehensive written summary – nutritional advice – supplementation advice – lifestyle interventions – integration of psychoneuroimmunological and hormonal clusters – mental and physical focus points – the detailed treatment plan with in-depth information on what we discussed The preparation, analysis, interpretation, and follow-up are included. You don't just pay for the consultation. You invest in the entire process. Who is this intake for? For people who: – are no longer satisfied with symptom management – have undergone multiple treatments without a real breakthrough – are chronically ill or – are healthy people who want to optimize their health preventively – are curious about new insights – are willing to look deeper This isn't a quick fix. This is a foundation. Practical Duration: 75-90 minutes Format: on-site and online For whom: new clients, individuals, and professionals Schedule directly via the online calendar. (Please indicate your preference for online or on-site)
N-Health® — Your flashlight in the jungle of cancer. A cancer diagnosis brings life to a standstill. And yet, everything must go on. You enter a world full of medical terms, treatment protocols, results, uncertainties, and choices. The standard pathway is often intensive, technical, and focused on the tumor. And rightly so — that is essential. But who looks at *you* as a whole? The in-depth oncological intake at N-Health® is a Deep Dive conversation in which the cancer itself is not treated, but you as a person take center stage within the entire biological system in which you function. I work in addition to the standard pathway, in collaboration with oncologists and other medical specialists. Not alternative. Not opposed. But integral, scientific. What I do during this intake I take ample time to map out your current situation. Not only the diagnosis and the treatment plan, but also: – the state of your immune system – metabolic flexibility and energy regulation – mitochondrial function – hormonal balance – neuro-immunological load – inflammatory activity – stress axis regulation – mental and emotional resilience – lifestyle, nutrition, and recovery capacity In addition, we look at factors that may have been exerting an influence for some time: – previous stress moments in life – chronic stress – inflammatory history – metabolic dysregulation – transgenerational influences – old patterns that are still having an effect Not to assign blame. But to understand the connections. Why this is important Standard oncological treatment focuses on tumor control via surgery, chemotherapy, immunotherapy, radiotherapy, or other targeted therapies. These pathways are life-saving and form the basis if you are already in such a pathway. My role is complementary. Among other things, I investigate how your internal environment can be supported in such a way that: • your immune system functions optimally • your body tolerates treatments better and treatments are more effective • recovery capacity is supported • focused on supporting the body in managing side effects where possible and enabling regular treatments to work better • focused on supporting balance in inflammatory processes • energy levels remain as stable as possible or are even increased • the body is in the most favorable physiological state possible And much more…… A well-regulated body responds differently to treatment than an exhausted body. And that applies to recovery as well. I closely follow the latest scientific developments in the fields of oncology, immunology, and metabolic therapies, ensuring that advice aligns with current insights and can be safely integrated into your existing treatment plan. Always in alignment. Always complementary. Always responsible. From current situation to a strong foundation During the intake, we clearly map out: • where you currently stand • how your system functions as a whole • which factors may hinder recovery • which protective factors can be strengthened From there, we develop a personalized, supportive treatment plan focused on: – nutrition – supplementation – lifestyle – stress regulation – neuro-immunological balance – hormonal and metabolic stability – mental support With the aim of strengthening your coping capacity, resilience, and internal regulation within the standard treatment process. I also support your environment, the people around you who are also dealing with this. Including preparation, analysis, and follow-up, and I assist with interpreting hospital results. You will receive comprehensive intake forms in advance. Any laboratory results and medical reports are carefully analyzed. During an on-site consultation, we additionally examine cellular energy production to gain insight into functional capacity at the body cell level. (This part is not available online.) Afterwards, you will receive: – a comprehensive written summary of the consultation – a comprehensive interpretation of all clusters (psychoneuro-immunological, hormonal, metabolic) – nutritional advice – supplementation advice (if you would like a schedule for this, it is not included in the consultation costs; however, you will receive it in writing – lifestyle advice – the detailed supportive treatment plan with multiple interventions, which we will outline further throughout the entire process The investment covers the entire process: preparation, analysis, interpretation, and follow-up, not just the consultation time You are not alone A cancer diagnosis often feels like entering a jungle. Unknown territory. Overgrown. Unpredictable. My role is not to walk the path for you. But to bring light. So that you understand what is happening. So that you can make choices based on knowledge. So that your body stands as strong as possible within the journey you are undertaking. N-Health® — Your flashlight in the jungle of cancer.
