I've been investigating functional medicine testing for years, but Evan Brand has run more than 5,000 of these specialized lab panels - putting him in the top 10 worldwide. And what he's discovered will challenge everything you think you know about health problems. We're talking about parasite infections in 80% of people tested, mold toxicity reversing autism diagnoses, and environmental toxins showing up in three-year-olds at higher levels than 80-year-olds. This isn't about adding more supplements to your routine. It's about understanding why your body isn't working the way it should. Evan walks through the specific biomarkers that reveal gut infections, mycotoxin exposure, heavy metal toxicity, and Lyme disease - conditions that conventional medicine rarely tests for but that could be driving your symptoms. This conversation will shift how you think about root causes versus symptom management. Knowledge is power - and these testing tools give you data your body has been trying to communicate for years.
