Welcome back to Beautifully Broken, where healing meets high performance. Today, I’m joined by Dr. Chad Yarbrough, a pioneer in genetic testing who’s changing the way we think about privacy, precision, and personalized care. Dr. Chad takes us from his early days in functional medicine—watching nonverbal kids go verbal and infertility cases resolve—to building his own lab for complete data control.

We dive deep into the science of SNPs, alleles, and the epigenome, and how to interpret your genetic report without panic or paralysis. Dr. Chad explains why knowledge truly is power, how to avoid being sold unnecessary supplements, and why environment and lifestyle are still the ultimate levers for gene expression. You’ll also hear real-world stories of patients reversing early dementia, overcoming histamine intolerance, and reclaiming their vitality by aligning with their genetic strengths.

This is a masterclass in genetic literacy, data privacy, and actionable wellness. If you’ve ever felt overwhelmed by health advice online, this conversation will leave you clear, empowered, and ready to take ownership of your biology.
