Visit the Store Visit the Store Thorne offers a choice of nutritional supplements to support an active lifestyle and to achieve goals – no matter what they are. Although there are many different paths to peak performance, what remains constant is meeting basic hydration and electrolyte needs, maintaining the body’s normal inflammatory response, and getting enough sleep. Just as fueling activity is important, so is the importance of maximizing recovery from that activity. Implementing an effective recovery strategy involves accounting for the metabolic demands of training, rehydrating, and supporting recovery from injury. Many Thorne products offer healthy supplementation to meet these needs. Thorne's Sports Performance products are trusted by athletes and health-care practitioners to allow individuals to personalize their pre- and post-workout routine based on their specific needs. 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 - and ultimately better health. 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. Our Charleston, SC facility is third-party certified. 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, while most competitors test only one or two times. We test our raw materials, in-process batches, finish products, and product stability for each product. We'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.
