What Do Our Clients Say?

FDN has helped with my own health tremendously!  When I first enrolled, my health was very poor (despite doing all the right things) and I was having difficulties functioning normally.  Although I suspected ‘what’ my challenges were, having them confirmed via the lab testing was VERY motivating. Having a greater knowledge (‘why’) and a working plan to resolve things (‘how’) has given me the hope and confidence that I’ll be feeling like a (retired) super hero again soon.  I’m beyond grateful to FDN!!!

I had been experiencing some traumatic stress over the last few years. I had no idea that I had been operating physically in an acute response taking care of everyone else and not myself. When I spiraled down, it happened fast and I found myself in exhaustion phase.  My 205 was an eye opener as well as the 101 and an excellent learning tool.  No wonder I couldn’t sleep!

The levels of health I have regained from only the first two tests as well as going through all aspects of DRESS have been amazing. I have energy levels that I haven’t had for 10 years! The brain fog has significantly gone down. The widespread pain is manageable even with a manual labor job. I am well on my way to fully recovering from fibromyalgia which has crippled me for the past 10 years. I owe FDN a lot. I’d like to thank Reed and all of FDN for sharing this knowledge and I hope to help spread it! Filling the ‘needs gap”.
