BUILD A CLINICAL UNDERSTANDING OF IMMUNOLOGY IN 8 WEEKS
WITH IMMUNOLOGY FOR DIETITIANS & NUTRITIONISTS (IDN) 8-WEEK COURSE
Transform the way you care for patients.The immune system is central to how the body responds to food, infection, stress, injury, gut dysbiosis, hormones, environmental exposures, and metabolic dysfunction. When you understand immune signaling, inflammation, and the difference between normal immune activation and chronic immune dysregulation, complex cases become easier to organize and prioritize.
​
The immune system is the foundation of health. With this new expertise, you will have a clearly defined focus and a straightforward clinical path with patients of all levels of complexity.
IDN COURSE
IDN IS FOR YOU IF...
You are a healthcare practitioner who wants to better understand why some patients stay inflamed, reactive, fatigued, hormonally imbalanced, metabolically dysregulated, or symptomatic despite improving their diet.
You seek to understand how acute and chronic inflammation affect patient symptoms and nutritional status
You’d like to connect gut health, immune activation, autoimmunity, hormones, metabolism, and mitochondrial stress
You are looking for considerations when patients do not improve after gut healing and diet changes.
You want to interpret bloodwork and functional patterns through a more immunology-informed lens
You'd like to understand immune terminology so you can read research and communicate more clearly with other providers
You'd like to feel more confident working with complex patients without relying on generic protocols
IDN COURSE
BY THE END OF IDN, YOU WILL BE ABLE TO...
Understand how immune activation shapes symptoms, labs, and clinical patterns
Connect inflammation with gut health, autoimmunity, hormones, metabolism, mitochondrial stress, and chronic disease
Choose nutrition, lifestyle, supplement, and testing strategies with greater clarity
Approach complex cases with more confidence, precision, and clinical reasoning
BUT ABOVE ALL ELSE...
IDN is not about memorizing immunology. It is about learning how to think differently when patients are complex, inflamed, reactive, or not responding to standard nutrition strategies.
WHAT YOU'LL LEARN
Meet the Immune System
Learn the foundational language of immunology, including internal versus external inflammation, conflict and resolution, mitochondrial signaling, ROS, and cell communication.
WHY IDN IS DIFFERENT
Most functional nutrition education teaches protocols such as gut protocols, detox protocols, hormone protocols, supplement protocols.
​
IDN teaches the biology underneath the protocols.
You will learn how to think through the immune system’s role in inflammation, food reactivity, gut dysfunction, autoimmunity, mitochondrial stress, hormone disruption, metabolic dysfunction, and chronic symptoms.
This allows you to stop guessing, stop over-supplementing, and start building strategies that are better matched to the person in front of you.
THIS COURSE IS NOT FOR YOU IF...
IDN may not be the right fit if you are looking for a quick protocol, a supplement cheat sheet, or a plug-and-play system that tells every practitioner to do the same thing.
​
This course is for practitioners who want to understand mechanisms, ask better clinical questions, and think more clearly through complex cases.
Taught by
Stacy Seslowsky, RD, LDN, MS
Stacy Seslowsky is a functional nutrition dietitian with more than 25 years of experience in dietetics and advanced training in functional nutrition and immunology. She created IDN after realizing that many nutrition practitioners are taught what to recommend, but not enough about the immune mechanisms driving chronic inflammation, autoimmunity, gut dysfunction, food reactivity, and complex patient presentations.
​
IDN brings that missing framework into practical clinical education for dietitians and nutritionists.
