Build your IBD nutrition knowledge, grow your business & change lives.

Millions of people have inflammatory bowel disease (IBD), notably Crohn's disease and ulcerative colitis, and they struggle to eat and enjoy food. They need help from knowledgeable professionals. We know there are many RDNs who WANT to counsel IBD patients but don't feel comfortable due to lack of experience. 

That's why we created this course... 

If you're seeing or want to see more IBD patients (and they need you!), this comprehensive course (made up of >15 years clinical experience) will give you the tools and confidence you need to help your IBD patients feel better using food and nutrition.
