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 Products
Made 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.

Our Healing Purpose

As a division of Thorne Research, we offer the same quality standards in our animal product line as we do for our human products

We’ve developed the most advanced, scientifically-based veterinary formulas in the world, and we give veterinarians and pet parents the tools to use them more effectively.

Through science and education we help you gain more knowledge more efficiently so you can stay on the leading edge of nutritional support for companion animals.

Not only do our supplements heal animals more effectively (and that’s proven through research with every supplement we create), our educational efforts are designed so vets and pet owners understand the knowledge behind how animals heal.

Through the most advanced, scientifically-based supplements, plus education on how to more effectively use suplements and other beneficial practices, we can all heal more animals. It’s this combination of science and education that has made ThorneVet the leader in transforming the animal health product industry.
