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.

What We Cover:

• Jenn's backstory: clean living since high school, her son's diagnosis, and the audit that started Zebra
• The difference between micro- and nano-hydroxyapatite
• Why micro-hydroxyapatite may block your saliva's own remineralization system
• Nano particles and the blood-brain barrier, and why "industry-funded" matters
• How to read research: always start with the declaration of interest
• Fluoride concerns and the pineal gland
• The truth about heavy metals in natural products, and the affiliate ecosystem profiting from panic
• Prop 65 compliance and what it actually means
• Polyester floss and microplastic exposure at the gum line
• How "clean" and "natural" labels are unregulated by the FDA
• Lake dyes hidden in color index numbers (and why the Switch Natural app catches them)
• Carmine, "natural" pigments, and what's really in your lipstick
• Jenn's advice for parents navigating a serious diagnosis

A note on the Zebra Toothpaste and the Switch Natural App:

If you scan the Zebra Toothpaste in the Switch Natural App, you'll see the ingredient "flavor" flagged. 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.

The latest cosmetics legislation (MoCRA) was supposed to transform beauty safety in the U.S. But while we were all distracted during the 2025 holidays, the FDA quietly withdrew key safety rules from it.In this video, I’m breaking down the "MoCRA Betrayal" and the latest regarding Talc, PFAS, and Formaldehyde.IN THIS EPISODE• The Talc Rule Withdrawal: It's not just asbestos.• Teflon in Your Makeup: The FDA found forever chemicals and took zero action.• Formaldehyde Deadlines: Bans on hair-straightening products stall.• The EU vs. The U.S.: FDA at a standstill while Europe moves forward.The bottom line? We can’t wait for regulators to keep us safe.

I was inspired to record this episode after witnessing the silencing of legitimate safety concerns about cosmetic ingredients. In this video, I share the shocking retraction from a major beauty publication plus glaring examples of how "Big Beauty" is shutting down safety questions in the name of science.

In this episode, we’ll uncover:

- The Truth about Parabens: Why the industry is burying years of peer-reviewed research.

- The Sunscreen Scandal: Which ingredients are being detected in your bloodstream (and what the FDA says about it).

- The Fragrance Loophole: How one word on a label can hide hundreds of undisclosed chemicals.

- Industry-Funded Research: How to spot a conflict of interest in "safety" studies in seconds.
