When Jenn Thatcher's son was diagnosed with a brain tumor, one of only 26 documented cases in the world, she went home and audited every "clean" product her family was using. What she found in her toothpaste and deodorant became the foundation for Zebra, a wellness brand built on custom formulations, third-party testing, and black and white ingredients. In this conversation, Jenn and I get into the science behind hydroxyapatite (and why she pulled her own approved formulation a year into development), the difference between micro and nano particles, the industry-funded studies most consumers never look at, and why heavy metals in natural toothpaste aren't the scandal the internet wants you to believe. We also talk about the realities of manufacturing a truly custom product and why Zebra makes consumer-first decisions. If you've ever been duped by a nontoxic product, this one is for you.

I want to be transparent about why: "flavor" can sometimes be a generic term that masks undisclosed synthetic compounds, which is why the app flags it. In this case, Jenn confirmed that the flavor used is organic and that every component is naturally derived, disclosed to her, and vetted. The app is doing its job of flagging a potentially risky ingredient, and this disclosure is the brand doing theirs. Both matter, and that nuance is something the app's automated scan can't capture on its own. Help spread the word. Rate, review, share.
