FROM OUR FOUNDER – REED DAVIS
FROM OUR FOUNDER – REED DAVIS
Over 20 years ago, I recognized clients were caught in a “cycle of trial and error” and I committed to being the last person they needed to see. While working with top leaders in alternative medicine, I ran thousands of labs on thousands of people and learned to identify “healing opportunities.” Using all-natural, drug-free protocols I made my own observations about who got better and who didn’t, codifying which “general principles of health building” would outperform “specific treatments” being provided by standard and even alternative medicine.
And through this work I then developed the Functional Diagnostic Nutrition Certification Course and D.R.E.S.S. for Health Success
Protocol to educate and empower as many people as possible to get well and stay well naturally, so they, in turn, may empower others to do the same.

Lab&Learn 7 – MRT: Identifying Food-Induced Inflammatory Reactions w/ Evan Transue
MRT: Summary The Lab&Learn provides an exploration of food sensitivities, allergies, intolerances, and celiac disease. It begins by distinguishing between food sensitivities and food allergies, explaining that allergies are IgE-mediated immune responses, while sensitivities can involve other immune reactions. The script also clarifies that food intolerances are not immune responses but are often related to digestion issues, such as lactose intolerance.
