Thorne's Sale to P&G and What It Means for Your Pet

On August 3rd, Thorne announced a $3.8 billion sale to Procter & Gamble. That same morning, the family running the veterinary side of that business announced their own news: they were stepping away from the Thorne name entirely to become PetDomain, a fully independent, family owned company.

In this episode, Dr. Angie and JoJo sit down with PetDomain owner and CEO Alex Pearson, whose father joined Thorne over thirty years ago and who has personally run the veterinary supplement line since 2019, to talk about what led to the split and what it means for the pet parents who have trusted these products for years.

Alex walks through what family ownership looks like day to day: sourcing ingredients from trusted, longtime partners, testing every product for heavy metals and contaminants before it ships, and randomly retesting products already on the shelf to confirm they still deliver full potency months and years later. He talks candidly about why proprietary blends make it hard for pet parents to know what they're really giving their pets, and why PetDomain discloses full ingredient amounts on every label instead.

The conversation also covers what NASC certification means, how to think about supplement dosing for dogs and cats, and why Dr. Angie often recommends pet parents use fewer, better dosed supplements rather than more.

This is a family business built by people who grew up in this industry and still answer the phone themselves. Boulder Holistic Vet has used and trusted these products for years, including PetDomain's Probiotic Support Formula, available in our shop.

Key Takeaways

  • Formulations, sourcing, and testing protocols have not changed with the split from Thorne.
  • Proprietary blends can hide exact ingredient amounts from pet parents. PetDomain discloses full amounts on every label.
  • NASC certification is one practical way pet parents can vet a supplement brand's manufacturing and testing standards.
