4Life Research

Overview

4Life Research was founded in 1998 by David and Bianca Lisonbee in Utah, built around Transfer Factor, an immune-support ingredient the founders licensed and commercialized as the company's flagship product line. The company grew quickly in its early years and has since expanded into additional supplement, skincare, and nutrition product lines sold through a network of independent distributors/affiliates rather than retail stores. Today 4Life is headquartered in Sandy, Utah, and operates as a global direct-selling business with offices and distributor networks across multiple continents, including active markets in the United States, Latin America (Mexico, Puerto Rico, Dominican Republic, Colombia, and others), and parts of Europe and Asia. The company remains privately held, registered as an LLC in Utah. Bianca Lisonbee, co-founder, passed away in 2023. 4Life sells its products through independent distributors under a direct-selling/network-marketing model. Third-party industry sources describe its plan using both unilevel- and binary-related terminology, but 4Life's own compensation-plan documentation was not directly accessible for verification in this research, so the exact plan structure is not confirmed here and is omitted.
