Sourcing Exceptional Ingredients
We develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility.
Manufacturing the Right Way
We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States.
Four Rounds of Review
We run four rounds of testing for each of our products. We have invested in two state-of-the-art in-house laboratories that allow us to conduct four rounds of testing. We test our raw materials, in-process batches, finish products, and product stability for each product.
Our Impact
At Thorne, we believe that doing our part to protect the natural world and its most valuable resources goes hand in hand with our product quality standards.
