At Douglas Laboratories, there is no greater mission than assuring that each and every supplement produced is of the highest quality. Douglas Laboratories Emblem of Quality assures that only the finest raw materials are being used, and that all manufacturing is performed under the strictest of guidelines. Because Douglass Laboratories’ products are developed specifically for exclusive distribution by healthcare professionals, Douglass Laboratories’ emblem has become a recognized symbol of quality that patients around the world have come to rely upon and trust.
