Trust. It's our secret ingredient.
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.
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.

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.
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.

The Thorne Difference.

For more than 25 years, Thorne has relentlessly pursued the highest possible quality and bioavailability in dietary supplements. At Thorne, we actually manufacture products that we sell – a key difference that allows us to control every aspect of the manufacturing process and ensure that every Thorne product is in pure, completely hypoallergenic form, and without the common additives, flowing agents, and binders used throughout the industry.

A few other companies have tried to do what we do, and many others claim to have the same philosophy and quality, but nobody has been able to duplicate what our clients call "Thorne Quality." We have changed the industry in many ways over the past two decades, and we continue to raise the bar and set new standards in product formulation, raw material purity, manufacturing, and quality control.
