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.

Fun facts about me:

  • 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.
