Niagen Bioscience Secures New U.S. Patent Covering Intravenous and Injection Formulations and Methods of Use for Nicotinamide Riboside (NR), Niagen®

Patent strengthens Niagen Bioscience’s intellectual property moat in fast-growing NAD+-boosting IV and injectable delivery formats, supporting commercial expansion and deterring infringers

Niagen Bioscience, Inc. (NASDAQ: NAGE), the global authority on NAD+ (nicotinamide adenine dinucleotide) with a focus on the science of healthy aging, today announced the broadening of its NAD+ precursor intellectual property (IP) portfolio with the newly granted U.S. Patent No. 12,558,367 , which covers the methods of use of nicotinamide riboside (NR) and derivatives in intravenous and injectable formulations.

Rob Fried, CEO of Niagen Bioscience, commented, “This patent expands our intellectual property for our patented NR ingredient, Niagen ^® , into IV and injectable delivery formats. With expected protection through 2044, it supports Niagen’s exclusivity in delivering a superior IV and injectable product with significantly faster delivery and improved comfort for patients across our expanding U.S. clinic footprint.”

Under its Niagen Plus product portfolio, Niagen Bioscience developed a next-generation intravenous formulation of pharmaceutical-grade Niagen designed to support healthy aging and longevity at the cellular level. Compared to traditional NAD+ IV, the aqueous-based intravenous Niagen formulation supports faster infusions and elevates NAD+ levels higher without the severe side effects of NAD+ IV, reinforcing the commercial relevance of this newly issued patent ( Reyna et al., 2026 ; Hawkins et al., 2024 ).

Niagen Bioscience continuously evaluates and investigates next-generation NAD+ precursors at the forefront of the burgeoning healthy aging category. The company owns and licenses a robust, secure portfolio of over 100 patents covering its flagship Niagen ingredient, the most efficient and high-quality NAD+ precursor on the market, as well as other NAD+ precursors.

Further reinforcing its leadership in the space, the newly issued U.S. Patent No. 12,558,367 adds meaningful protection for NR in IV and injectable delivery formats, with claims spanning aqueous formulations, multiple administration routes, defined administration parameters, select NR salt forms, and combination use with other NAD+ precursors. By extending the Company’s defensible IP footprint in this growing segment, the patent supports additional commercial pathways and partnerships and reinforces the durability of Niagen Bioscience’s Niagen product portfolio.

Niagen IV is available at over 1,200 healthcare, wellness, and longevity clinics across the U.S. Use the clinic locator at www.niagenplus.com to find a provider near you. For additional information on Niagen, visit www.niagenbioscience.com .
