Since 1999, ChromaDex a publicly traded, innovative natural products company has been providing proprietary, science-based solutions to a variety of industries, including the dietary supplement, animal health, and pharmaceutical industries. In July 2013, Thorne Research formed a strategic partnership with ChromaDex to develop and commercialize a number of ground-breaking natural products. Two of the initial outcomes of this collaboration are the commercialization of pterostilbene – a ChromaDex-branded, bioavailable resveratrol product – and Niagen – a ChromaDex-branded nicotinamide riboside marketed by Thorne Research as NiaCel.

In 2014, Thorne Research and EXOS (formerly Athletes Performance) formed a partnership to provide distinctive, evidence-based nutritional supplements and educational programs to professional and elite athletes. This venture combined Thorne Research's expertise in manufacturing high-quality, evidence-based supplements with EXOS' recognized leadership in integrated performance training and nutrition.
