New Crystalline Salts of Nicotinamide Riboside as Food Additives


Schabert, Günter; Haase, Robert; Parris, Jaclyn; Pala, Laura; Hery-Barranco, Adrian; Spingler, Bernhard; Spitz, Urs (2021). New Crystalline Salts of Nicotinamide Riboside as Food Additives. Molecules, 26(9):2729.

Abstract

NR+ is a highly effective vitamin B3 type supplement due to its unique ability to replenish NAD+ levels. While NR+ chloride is already on the market as a nutritional supplement, its synthesis is challenging, expensive, and low yielding, making it cumbersome for large-scale industrial production. Here we report the novel crystalline NR+ salts, d/l/dl-hydrogen tartrate and d/l/dl-hydrogen malate. Their high-yielding, one-pot manufacture does not require specific equipment and is suitable for multi-ton scale production. These new NR+ salts seem ideal for nutritional applications due to their bio-equivalence compared to the approved NR+ chloride. In addition, the crystal structures of all stereoisomers of NR+ hydrogen tartrate and NR+ hydrogen malate and a comparison to the known NR+ halogenides are presented.
