We're so much more than JUST a supplement manufacturer.
ThorneVet has developed the leading scientifically-based animal health supplement formulas in the world. And we provide veterinarians and pet owners with information on why these formulas are better and how to use these products more effectively. This is why so many veterinarians recommend our products and why pet owners trust giving ThorneVet supplements to their companion animals.
Here’s how we set the standards in the animal supplement industry:
Carefully Considered ProductsMade Without Compromise

The single-most important reason ThorneVet is trusted by veterinarians and pet owners around the world is because they know ThorneVet products are made with the highest degree of quality possible.
They know this, in part, because Thorne Research, our parent company, is the sole provider of nutritional supplements to 11 U.S. National teams, as well as dozens of teams and hundreds of athletes in the NFL, NBA, MLB, and UFC. If Thorne quality is good enough for our Olympic athletes, then we hope ThorneVet quality is good enough for your companion animal.
