Crystalline complex, method for producing thereof, and composition

Abstract

A novel crystalline complex of nicotinamide mononucleotide that is stable and highly safe is provided. The crystalline complex contains nicotinamide mononucleotide and a phenylalanine-based compound. The crystalline complex has L-phenylalanine or aspartame as the phenylalanine-based compound. The crystalline complex having L-phenylalanine as the phenylalanine-based compound has peaks at diffraction angles (2θ) of 19.7±0.2°, 26.4±0.2°, and 32.8±0.2° in a diffraction pattern of powder X-ray diffraction measured with a Cu-Kα ray as an X-ray source. The crystalline complex having aspartame as the phenylalanine-based compound has peaks at diffraction angles (2θ) of 7.0±0.2°, 10.7±0.2°, 14.4±0.2°, and 29.1±0.2° in a diffraction pattern of powder X-ray diffraction measured with a Cu-Kα ray as an X-ray source.
