Niagen Bioscience is a global bioscience company focused on commercializing nicotinamide adenine dinucleotide (NAD+) and related compounds to support healthy aging, capitalizing on the decline in natural NAD+ levels as humans age. The company operates through multiple segments: a consumer products business selling dietary supplements under the Tru Niagen brand containing proprietary nicotinamide riboside chloride, an ingredients segment supplying both food-grade and pharmaceutical-grade NAD+ precursors to manufacturers and compounding facilities, and a pharmaceutical development division pursuing therapeutic applications. Revenue is generated primarily through direct-to-consumer e-commerce and retail distribution of finished dietary supplements, ingredient licensing to manufacturers, and pharmaceutical-grade supply to FDA-registered outsourcing facilities, with the company differentiating itself through extensive scientific research partnerships, clinical trial validation, and patent protection in the competitive health and wellness market.
