Niagen injections work by delivering a highly efficient, pharmaceutical-grade form of nicotinamide riboside (NR), a direct precursor to NAD+. Once in the body, NR is rapidly converted into NAD+, a vital coenzyme that fuels cellular energy production, supports DNA repair, enhances mitochondrial function, and promotes overall cellular health. As NAD+ levels naturally decline with age, stress, and inflammation, Niagen helps restore these levels, improving metabolism, cognitive function, and recovery while reducing oxidative stress and inflammation. By replenishing NAD+, Niagen injections provide a powerful boost for energy, longevity, and optimal wellness.
