Sourcing Exceptional IngredientsWe 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 - and ultimately better health. | Manufacturing the Right WayWe 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. Our Charleston, South Carolina, manufacturing facility is GMP certified by NSF International, a well-recognized independent third-party certification organization. | Four Rounds of TestingWe perform four rounds of testing for each product we manufacture – far above the industry standard. Thorne has invested in two state-of-the-art in-house laboratories that enable us to conduct four rounds of testing, including raw material testing, in-process batch testing, finished product testing, and expiration date stability testing for each lot of product that we manufacture. | Thinking SustainablyWe're thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards. |
