July 2021 in “Molecules/Molecules online/Molecules annual” This study demonstrated that an LC/MS-MS method could effectively detect and quantify the vitamin B3 vitamer nicotinamide in human hair, suggesting its potential use for long-term deficiency examination.
January 2026 in “Annals of Clinical Endocrinology and Metabolism” This narrative review summarizes evidence on NAD⁺ biosynthesis and turnover, highlighting that while NAD⁺ precursors like NR and NMN consistently boost NAD⁺ levels in preclinical and human studies, clinical outcome results remain varied, indicating a need for more standardized human trials.
September 2025 in “Cosmetics” In this study, oral supplementation with NMN for 12 weeks in middle-aged Japanese women significantly increased hair growth density and diameter and improved subjective assessments of hair texture and quality of life, with no significant changes in hair hormone concentrations observed.
February 2026 in “International Journal of Cosmetic Science” This study found that a novel Mito-Activator Complex, containing nicotinamide and epigallocatechin gallate, significantly increased hair density and growth in a 6-month human trial, with no adverse effects reported, potentially offering a new approach to hair loss treatment through mitochondrial activation.
