A Functional Health Framework That Gets Results | D.R.E.S.S. For Health Success™.

D.R.E.S.S For Health Success is a proven framework that helps restore function within the body, no matter what symptoms or diagnosis a person has.This is the exact framework being used by thousands of FDN Practitioners around the world today, and it works.

Let’s break it down. 

D for Diet

Leverage functional nutrition to fuel healing. Learn how to create nourishing protocols based on functional lab results so your clients get exactly what they need to heal & restore balance. This is about saying goodbye to calorie-counting & restriction, and giving the metabolism a total reboot so it can function the way it’s intended to.

R for Rest

Master sleep hygiene & rest. You’ll learn exactly why deep sleep is so crucial to the healing process. We’ll review proper sleep hygiene & ways to help your clients improve sleep quality. We’ll also go over some common ways to measure sleep quality for clients who are interested in tracking their progress. 

E for Exercise

Learn to adjust intensity & frequency. We’ll teach you how to select the right type of exercise, intensity & frequency to accommodate you or your clients health goals. More is not always better! In fact, when the body is stressed, exhausted, or dealing with certain forms of disease, too much intensity can interfere with the healing process. 

S for Stress Reduction

Uncover hidden stressors for better results. Stress reduction is a key element to any successful health building program. When stress is left unresolved, the body begins to break down, and symptoms eventually appear. Learn to uncover hidden stressors before they’ve made themselves visible, so you can accelerate healing & optimize health. 

S for Supplementation

Harness the power of targeted supplementation. High-quality supplementation can be a game changer, when done strategically. Learn how to choose the most effective supplements for you + your client, based on functional lab results.

“I had already completed the Institute for Integrative Nutrition (IIN) health coach certification, but...

As a client working with an FDN practitioner, I saw how quickly the approach helped me get to the root of my health issues despite doctors saying there was nothing wrong. Having seen the radical transformation in my own health, I knew I had to become certified. I had already completed the Institute for Integrative Nutrition (IIN) health coach certification, but it was clear to me that FDN had another layer of knowledge that would benefit my clients.”
