Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business	Nature of Business Niagen Bioscience, Inc. and its wholly owned subsidiaries, ChromaDex, Inc., ChromaDex Analytics, Inc., NAD Pharmaceuticals Corp., ChromaDex International, Inc., ChromaDex Asia Limited, Asia Pacific Scientific, Inc., ChromaDex Asia Pacific Ventures Limited, ChromaDex Europa B.V., and ChromaDex Trading (Shanghai) Co., Ltd. (collectively, “Niagen Bioscience” or the “Company”) are a global bioscience company dedicated to healthy aging. The Niagen Bioscience team is engaged in research on nicotinamide adenine dinucleotide (NAD+), an essential coenzyme that is a key regulator of cellular metabolism and is found in every cell of the human body. NAD+ levels in humans have been shown to decline with age, among other factors, and may be increased through administration of NAD+ precursors. Niagen Bioscience is the innovator behind the NAD+ precursor nicotinamide riboside chloride (“NRC” or “NRCL,” commonly referred to as “NR”), commercialized as the flagship ingredient Niagen®, available in both food and pharmaceutical grades. Nicotinamide riboside chloride and other NAD+ precursors are protected by Niagen Bioscience’s patent and/or licensed rights portfolio. The Company delivers food-grade Niagen® as the sole or principal dietary ingredient in its dietary supplement consumer product line, Tru Niagen®, and has expanded its consumer product offerings to include a topical skincare product incorporating Niagen® as the principal ingredient. Furthermore, the Company develops and commercializes proprietary ingredient technologies, including food-grade Niagen® and pharmaceutical-grade Niagen®, supplies these ingredients as raw materials to manufacturers of consumer products and U.S. FDA-registered 503B outsourcing facilities, respectively, and supports clinician-directed telehealth access to prescription-based Niagen® offerings. In addition, the Company is developing certain molecules for potential therapeutic applications, including rare genetic diseases and aging related disorders. These activities include research and development efforts, including preclinical and clinical studies and regulatory planning, and the Company does not currently generate revenue from these activities. The Company may continue internal development and may also pursue strategic collaborations or licensing arrangements. Prior to February 24, 2026, the Company also provided natural product fine chemicals, known as phytochemicals, and related research and development services through its analytical reference standards and services operating segment. This operating segment was sold as of such date. Certain assets associated with this segment were classified and presented as held for sale on the Condensed Consolidated Balance Sheet as of December 31, 2025. The results of operations of this segment are included in continuing operations for all periods presented, as the disposition did not represent a strategic shift that would have a major effect on the Company’s operations or financial results and, therefore, did not meet the criteria for discontinued operations treatment. Refer to Note 4, Business Segments and Concentrations, for further information.
