Why Functional Nutrition Resources?

Are you tired of hearing everything is normal when you know deep down it is not?  Of pushing thru day after day and just surviving instead of thriving.  We get it.  You want a team who listens carefully and has the ability to determine the root cause or “why” of your concerns and create a customized plan or blueprint just for you.  You want true solutions and long lasting results-not another cookie cutter approach.   

At Functional Nutrition Resources a functional medicine clinic in Tulsa, OK,  we practice functional medicine and nutrition which means we  take a holistic approach to health that focuses on the whole, interconnected person versus just symptoms or disease.  Combining nutrition with the essential elements inside of functional medicine we address the root cause or why behind your conditions or symptoms.  We want you to experience true health and healing but also have the tools and coaching to successfully continue your journey the rest of your life.  

After years of seeing this happen with practice members, Jennette Berry, RDN, LD opened a functional medicine clinic in Tulsa, OK that not only helps them improve their overall wellness and health, but also gives them the tools and coaching to successfully continue their journey for the rest of their lives.
