When your child is sick, do you know what’s really in the medicine you’re giving them? In this powerful episode, Dr. Taz sits down with David Johnson, co-founder and CEO of Genexa, the first clean medicine company in the U.S. Born into a naturopathic family and driven by fatherhood, David shares the emotional and entrepreneurial journey that led him to question what's hiding in over-the-counter medications and how 90–95% of most medicines are made up of inactive ingredients, many of which are banned in other countries.


Together, they dive into:

  • Why common ingredients like red dye, titanium dioxide, and artificial sweeteners may be harming our children.
  • The difference between "natural," "organic," and truly "clean" medicine.
  • How Genexa is disrupting Big Pharma from the inside out and the personal cost of that battle.
  • The heartbreaking moment that changed everything for David and shaped his mission.
  • What YOU need to know to protect your family and advocate for better health policies.

Whether you're a parent, practitioner, or wellness advocate, this episode will leave you questioning the status quo and inspired to demand better.

About David Johnson


David Johnson is the Co-Founder and CEO of Genexa®, the first clean medicine company. Born and raised in a family of naturopathic practitioners, David has been connected to natural health and wellness his entire life. After becoming a father in 2010, he was surprised to discover the artificial dyes, flavors, preservatives, and common allergens found in most children’s over-the-counter medicines. Seeing a need for clean options, David co-founded Genexa in 2014 to create medicine made with the same effective active ingredients as the leading brands, but without unnecessary artificial additives. Genexa believes in putting People Over Everything® and is on a mission to revolutionize the medicine aisle by offering clean choices for families everywhere.
