13 YEARS OF EXPERIENCE


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?
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.

EXTENDED INTAKE
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.

EXTENDED INTAKE
15 minuten deskundigheid, helderheid zonder traject. Soms is er geen volledig behandelplan nodig. Soms is er alleen richting nodig. Het Vragenkwartiertje bij N-Health® is een kort, krachtig online consult van 15 minuten waarin u één, of maximaal twee, gerichte vragen kunt bespreken of een korte evaluatie kunt doen. Voor uitgebreide analyses, behandelplannen of schriftelijke verslaglegging is een reguliere intake of voor bestaande clienten een vervolgconsult meer passend (zie bij contact) Het Vragenkwartiertje bij N-Health® is een kort, krachtig consult van 15 minuten waarin u één concrete gezondheidsvraag kunt voorleggen. Zonder uitgebreide intake. Zonder verplicht vervolg. Zonder dat u al cliënt bent. U mag volledig nieuw zijn. Of u mag een bestaande client zijn. Zie het als een soort helpende hand gedurende uw reis net als de ANWB. Voor wie is dit geschikt? Voor particulieren die: – een specifieke klacht, vraag of inzicht beter willen begrijpen, curatief of preventief – twijfelen over een uitslag of advies (kan ook welke via een ander is verkregen als 2d opinion) – willen weten of een uitgebreider traject of intake zinvol is – snel professioneel inzicht willen zodat ze zelf weer verder kunnen, als soort hulp voor onderweg Professionals kunnen terecht op de subpagina op deze webiste: n-health-academy (onder more....) Wat kunt u verwachten? In 15 minuten ontvangt u: • een scherpe analyse van uw vraag • duiding vanuit neuro-immunologische en metabole samenhang • concrete richting of vervolgstappen • helderheid over wat wel of juist niet nodig is Geen standaardantwoord. Geen oppervlakkige reactie. Maar geconcentreerde expertise. Persoonlijk en vaak geheel vergoedbaar voor particilieren vanuit een aanvullende zorgverzekering (meer info verderop deze website bij wie ben ik en vergoedingen) Waarom dit werkt: Veel gezondheidsvragen hoeven niet direct in een langdurig traject te worden geplaatst. Soms is het voldoende om: – patronen te herkennen – een verkeerde aanname te corrigeren – een ontbrekende factor te benoemen – of simpelweg geruststelling te krijgen Het Vragenkwartiertje is bedoeld als professioneel kompas. Een moment van afstemming. Een kort maar waardevol ijkpunt. En kan zo vaak ingeboekt worden als men wenst Praktisch Duur: 15 minuten Vorm: online Voor wie: nieuwe én bestaande cliënten, particulieren Direct in te plannen via de online agenda.
