RACHEL SCHEER NUTRITION · ESTABLISHED 2018
The RSN Institute trains coaches and medical professionals in functional nutrition - with the clinical reasoning, framework, and lab testing interpretation that separate real practice from protocol-reading. Then we help our graduates launch, grow, or be placed in a thriving practice.


A client can have the right assessment and the right labs ordered and still struggle to heal - because the interventions weren't applied with proper sequencing.
Most functional practitioners don't follow a clinical model. They find root causes and throw protocols at them - lab-and-supplement combinations deployed in parallel, without the proper order. The RSN Method is the clinical framework we teach inside the institute - a sequenced approach that addresses the body in the order that allows healing to occur. The framework is what turns a certificate into a career.
Most certification programs end at the credential. The RSN Institute treats certification as the beginning — with equal investment in how our graduates actually build careers.

I was told I needed surgery to remove my large intestine. I refused. Years of functional nutrition work rebuilt my body - and became the methodology I now use to train the next generation of practitioners.

I came in already credentialed and thought I'd be reviewing familiar material. By module three I realized I'd been treating downstream effects for ten years. The sequencing alone rewired how I work with every client

I tried 2 other certifications before RSN, neither gave me a real framework - just protocols. Rachel teaches you how to think about the client. That's the thing no one else teaches.
