 "In April of 2018 I was 180 pounds 57 years old and experiencing fatigue, water retention, stiffness in joints especially feet and back, kind of hard getting into and out of the car, feeling like I’m older than I was. I read Cathy Hains's article in Marlene’s Sound Outlook about the MRT food sensitivities testing, read up on it and decided it could be useful information that would help me. 

Unlock the power of comprehensive nutrition care

Nutritional DNA Testing -The Next Frontier

Some of the best weight loss tips are in your genes. Get the best nutritional DNA testing.

 Study results flip flop all the time, partially because they don't account for genetic differences in each individual in the cohort. Cathy has searched high and low for the best genetic nutrition test and has found Nutrigenomix®  to be one she can trust. 

LEAP MRT® Food Sensitivity Testing & Diet Therapy

Lose weight. Migraines, IBS, Crohn's or Ulcerative Colitis, headaches, joint pain, or MS

Get to the bottom of food sensitivities. Got migraines, IBS, joint pain, inflammation? There's no need for a blind elimination diet when you can finally pinpoint triggers. This is not the less reliable IgG testing, but rather a more much accurate food intolerance testing (not allergy testing).
