For more than 25 years, Thorne Research has set the standard for exceptional formulations, quality, and purity in the dietary supplement industry. At Thorne Research, our mission is to enhance the health and well-being of people by providing superior dietary supplements that have the highest level of quality and purity thereby creating the most respected and valued company in the dietary supplement industry.


Setting a higher standard.
While Thorne operates under comprehensive GMPs, we go a step further to meet the stringent standards set by Australia's Therapeutic Goods Administration (TGA). Thorne's TGA "medicinal products" certification is the same required of Australian pharmaceutical manufacturers.

Purity means performance.
At Thorne, we know the purity of a supplement's raw ingredients makes the difference between an effective, well-tolerated product and an inferior, poorly absorbed one that may even cause allergenic reactions. That's why our commitment to using the purest ingredients possible is nothing short of obsessive.

Trust. It's our secret ingredient.
No other dietary supplement manufacturer has earned the trust of leading research organizations like Thorne. We provide our technical and manufacturing expertise to prestigious institutions such as Columbia University, University of California, the U.S. Navy, and Tufts University.


We put quality and purity to the test.
Thorne is one of the few dietary supplement manufacturers to maintain a state-of-the-art testing laboratory in-house. We believe this is an integral component to providing superior product quality and purity, as it allows us to keep extreme and constant control of our entire manufacturing process.

Earning Experts' Trust
No other dietary supplement manufacturer has earned the trust of experts, such as research organizations and leading health-care practitioners, like Thorne Research has.

We have provided our technical and manufacturing expertise to numerous researchers, and our products are currently included in more than a dozen studies in such prestigious institutions as Bastyr University, Columbia University, University of California, the U.S. Navy, Oregon Health Sciences University, and Tufts University.

We've also earned the unwavering trust of thousands of health-care practitioners worldwide. Indeed, in many cases, a patient's life actually depends on the quality, purity, and integrity of our products. Undeniably, our actions throughout the years have always spoken louder than the rhetoric of our competitors. Confidence in Thorne is the single most important reason why practitioners turn to us for their critical dietary supplement needs.

In this competitive industry, the amount of money spent on advertising is tremendous, with all companies claiming they have the best products. Thorne's reputation hasn't been shaped through clever marketing, but rather through the unbiased scrutiny and approval of health-care practitioners throughout the world who discovered one important detail our products consistently produce positive results in their patients.

The Bottom Line?
Thorne is the only hypoallergenic dietary supplement manufacturer with the highest degree of purity that you and your most severely allergic, chemically sensitive, and immune-compromised patients can truly trust.
