Thorne Vet: People Committed to Healing Animals

We Honor the Human-Animal Bond

You only need to know one thing about the people who make up Thorne Vet: every one of us is passionately committed to healing animals.

We deeply honor the bond between humans and animals. All of us at Thorne Vet know and have experienced the emotional pain an owner feels when their animal is in a diseased state. We also understand the stress and obligation that you, as a veterinarian, are under to help animals heal. Therefore, Thorne Vet's mission is to help you and the other 50,000 veterinarians in private practice heal more animals, more effectively by providing you with the most potent, effective tools available.

How We Help You Facilitate Animal Healing

We know you are time challenged. Therefore, the fastest way we can help you get a quick understanding of the Purity-Healing Relationship is to simply look at a short list of what we at Thorne Vet consider to be ingredients that can negatively impact purity and thus the efficacy of a product. If you go to your own supplement shelf right now, you will be surprised to find that 98 percent of the products that you are currently giving your animals contain the compromising ingredients listed below.

Extensive research and Thorne's expertise and experience have led us to conclude that these components negatively affect purity and efficacy. (You will find these same compromising ingredients in the human supplements you are taking.) Because we believe these lubricants, binders and additives compromise purity, these are ingredients you will never ever see in a Thorne Vet product.

Thorne Vet's foundation of healing is made up of 4 Essential Elements:

1. Efficacy through Purity
2. Healing through Science
3. Transformation through Education
4. Helping You Choose

Our strict adherence to these four principles ensures that you and your clients will always receive the highest quality, most effective, bioavailable, and hypoallergenic animal health products in the world. As you can see on our Why Purity page, the effectiveness of any animal health product you use is substantially affected by its level of purity.

All of our innovative formulas are based on the latest scientific research and have been reviewed and tested by the most knowledgeable and experienced minds in our industry. You can prescribe Thorne Vet products knowing you are prescribing the best.

Thorne Vet knows that, in your practice, “Knowledge is Power.” Our website and monthly “Knowledge Minute” will continually keep you on the leading edge of the most relevant scientific advances in integrative veterinary medicine. We know how time-stressed you can be in your practice and we package these knowledge bytes in a manner that allows you to quickly and effectively assimilate the information. Click here to sign up for your monthly “Knowledge Minute.”

Thorne Vet is seriously committed to supporting your efforts to heal animals, any way we can, even if you don't use one of our formulas. This means that in the rare case Thorne Vet does not carry the particular product you are looking for... we will help you find it. Just contact us.
