Polymorphic form of reduced b-nicotinamide mononucleotide calcium salt, and preparation method and use therefor

Abstract

A compound NMNH calcium salt, in particular a polymorph of a reduced β-nicotinamide mononucleotide calcium salt and a preparation method therefor, a use thereof as a pharmaceutical ingredient, a health care product ingredient and a cosmetic ingredient or as a food additive, and a formulation containing same, belonging to the field of medicines, health care products, cosmetics and food additives. For the NMNH calcium salt polymorph, the crystal thereof displays long-term continuous stability, and compared with NMNH disodium salt, has significantly superior stability performance and anti-hygroscopic properties, and is more beneficial to long-term storage, promotion and market application. The NMNH calcium salt crystal is simple in preparation process, easy to control and suitable for large-scale production.
