What Is NMN and How Does It Support NAD+ Production: Complete Guide
NMN, or nicotinamide mononucleotide, is a naturally occurring molecule the body uses to produce NAD+. Enzymes convert NMN into NAD+, which cells need for energy metabolism, DNA-related functions, mitochondrial activity, and cellular maintenance. Human studies show that oral NMN can raise blood NAD+ levels, although evidence for broader benefits such as improved energy, metabolism, physical performance, or slower aging remains limited and mixed.
