MEET KARI — FUNCTIONAL GUT HEALTH DIETITIAN

I'm so glad you're here!

I'm Kari Natwick, and my passion is helping women find gut health empowerment. As a Registered Dietitian Nutritionist (RDN), Integrative and Functional Nutrition Certified Practitioner (IFNCP), and Certified Gastrointestinal Nutritionist (CGN), I specialize in guiding women through the maze of persistent digestive issues. From bloating, constipation, and diarrhea to gas, reflux, and abdominal pain, I'm here to create a personal roadmap for your gut healing.

My journey toward this field wasn't just professional — it was personal. Battling my own autoimmune thyroid disorder, digestive woes, and mold toxicity, I intimately understand the hurdles of managing chronic health issues.

My approach is not just about treating symptoms; it's about holistic healing. I delve into the intricate relationship between the gut and brain, recognizing the profound impact it has on our overall wellbeing. Through functional lab testing, a personalized gut-healing program, and education, I guide my clients toward improved wellness, increased energy, and hormone balance.

My mission is simple: to empower you on your path to vitality. I believe in creating a space where you feel heard, supported, and uplifted. When you take charge of your gut health, you're not just restoring balance in your body — you're reclaiming your energy to pursue your passions.

Witnessing the remarkable transformations of my clients fuels my passion every day. Together, let's embark on a journey toward optimal health and happiness.

I help women restore health by addressing the true roots of chronic symptoms—through advanced functional nutrition, nervous system regulation, and whole-person systems thinking—so healing becomes embodied, sustainable, and life-giving.

Many of the women I work with have already “done all the right things.” They’ve tried supplements, elimination diets, protocols, and testing, yet still don’t feel well.

My approach begins with a different understanding: healing isn’t something we force through willpower or aggressive protocols—it emerges when the body has the right conditions, capacity, and support.

I combine high-level clinical nutrition and functional testing with trauma-informed care and nervous system regulation. I use data—labs, history, patterns—to inform decisions, but I never reduce a person to numbers. Labs provide insight; they do not replace discernment.

I treat the gut as an ecosystem, the nervous system as foundational, and the body as intelligent.

Rather than starting with restriction or symptom suppression, I focus on building terrain—supporting digestion, mineral balance, detoxification capacity, metabolic resilience, and nervous system safety—so change can occur without overwhelm.

Food and botanicals are used thoughtfully and strategically, with an emphasis on nourishment rather than deprivation. I avoid unnecessary elimination diets and prioritize approaches that are realistic, sustainable, and supportive of long-term health.

At the heart of my work is embodiment. True healing does not happen through protocols alone. It requires attunement, pacing, witnessing, and reconnection to the body’s signals and needs.

My role is not to override the body, but to listen to it—so health becomes something you can maintain, not manage.

• I have a love for all things nature and the great outdoors.

• Being surrounded by nature is therapeutic and restorative.

• Whether it's hiking, backpacking, cross-country skiing, snowshoeing, paddle boarding, canoeing, or kayaking, I'm always up for an adventure!

• Cooking is another passion of mine.

• I'm a master gardener with an emphasis on vegetable gardening. I believe in the power of growing your own food and connecting with the earth.

• Did you know that by incorporating whole, nourishing foods into your diet, you can help to support your digestive health and overall wellbeing.

I'm here to support you every step of the way in your journey towards optimal health. Let's work together to uncover the root causes of your health issues and help you transform your life.

High Clinical Excellence
I work with complex cases using advanced functional nutrition and testing while honoring the full context of each person’s life and physiology.

Whole-System Thinking
Health emerges from the interaction of biology, environment, nervous system capacity, and lived experience—not isolated symptoms.

Nervous System Safety First
Healing is limited by capacity. My care is trauma-informed, consent-based, and paced to support regulation and resilience.

Nourishment Over Restriction
I prioritize food and botanicals as medicine without unnecessary deprivation, supporting both human health and ethical, sustainable food systems.

Embodiment as Essential
Lasting change happens when women move out of override and back into relationship with their bodies.
