For over 20 years, Thorne Research has set the standard for exceptional formulations, quality, and purity in the nutritional supplement industry. Since our humble beginnings in 1984 in a small, rented space in Tukwila, Washington, with just two employees (Al and Kelly Czap, the two owners of the company), our philosophy has been the same - provide the purest supplements possible at a reasonable price. Our manufacturing plant, warehouse, and shipping facility in Sandpoint and Dover, Idaho covers 76,000 square feet and we have over 120 employees. Although the industry has changed dramatically, the Thorne philosophy has stayed the same - manufacture the finest, purest, highest quality nutritional supplements in the world. We understand that people's lives depend on our products and we take that responsibility very seriously
