Trusted ManufacturerFor more than 30 years, Thorne has been trusted by health-care practitioners who prescribe our products to their patients. In addition, our products are now recommended by U.S. National Teams and multiple professional sports teams for their elite athletes. Thorne products are a testament to Thorne’s mission to provide high-quality supplements that are tested for quality, safety, and efficacy. |
Individuals at high risk for mineral deficiencies include the elderly because of deteriorating digestion, children and teenagers because of poor diet, individuals who have an eating disorder, and anyone suffering from a chronic disease. Taking certain prescription medications can also cause mineral deficiencies. Because the mineral content of fruits and vegetables depends on the soil health a crop it is grown in, even a healthy individual who maintains a good diet can be at risk for a mineral deficiency because of mineral-depleted soils.
By their very nature, minerals are not particularly well-absorbed by the human body. In addition, various dietary, lifestyle, and health factors can have a negative impact on mineral absorption. One of the barriers to mineral absorption is overcoming the natural form the mineral comes in. Thorne’s mineral ingredients are primarily in their chelated form – the mineral is linked to an amino acid or an organic acid via a molecular reaction that provides a predictable, high quality, and hypoallergenic chelate. Thorne’s mineral supplements are designed for optimal absorption.
When the highest standards have been met, Thorne creates higher ones.

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, SC facility is third-party certified. |
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. |
