A customized approach to gut health

Tired of battling persistent gut issues and longing to reclaim your body's vitality? Leave behind generic solutions and embark on a journey to unravel the root cause of your gut symptoms, forging a path of harmony in your wellbeing.

I’m Kari Natwick, a functional gut health dietitian, known as the Gut Brain RD. Specializing in personalized gut health solutions, I guide women through a transformative journey, delving into the intricate gut-brain connection to address discomfort, pain, and lingering health challenges. Let’s partner together to craft a roadmap that cultivates lasting health and balance in the body.

I help women with:

GUT HEALTH CHALLENGES

I work with women who have been diagnosed with IBS, SIBO, Ulcerative Colitis, Celiac Disease, GERD, and EoE. I also work with women who have not been diagnosed, but have ongoing GI-related complaints, including diarrhea, constipation, bloating, and gas.

HORMONE IMBALANCES

If you’re experiencing PCOS, endometriosis, thyroid disorders, adrenal dysfunction, and hormonal imbalances, hormone testing can help address the underlying cause. After testing, we’ll craft a personalized approach to restore hormonal harmony and foster overall wellbeing.

AUTOIMMUNE CONDITIONS

Whether you're struggling with Hashimoto's thyroiditis, celiac disease, or other autoimmune symptoms, comprehensive testing can illuminate the root cause of your health challenges. Then we'll collaborate to develop a tailored strategy aimed at addressing the autoimmune dysfunction, guiding you toward restored health and vitality.

Meet the founder

My name is Kari Natwick, and I'm so glad you're here! I am a Registered Dietitian Nutritionist (RDN) and an Integrative and Functional Nutrition Certified Practitioner (IFNCP).

In short, I am passionate about serving people and guiding them into optimal health!

If you're a woman who has been burdened by chronic digestive issues, autoimmune conditions, fatigue, hormonal imbalances, inflammation, or you just want to reach optimal health, you first need to know that you're not alone — and I'm here to help.

My mission is to help women feel empowered, confident, hopeful, joyous, comfortable, safe, cared for, invested in, and like someone has their back and is going to work hard for them and alongside them to heal.

Why? Well, when it comes to doing the hard work to optimize your health, let’s just say, I’ve been there...

Get to know me!

Working on my health for decades, it was only until encountering Kari and her way of working that I finally found a path toward treating myself with sustained value. Kari has immense knowledge about protocols, supplements, and testing. But what really sets her apart as a guide is her way of helping to change one's way of thinking. This has been revelatory to me and has made all the difference. Brain fog, unneeded weight, exhaustion, undermining thoughts, and emotional malaise begin to fall away. This seemed at first like magic to me, but examining Kari's way of working, it all makes perfect sense. I highly recommend Kari Natwick, RDN, LD, IFNCP!
