Nicotinamide riboside, an orally active NAD⁺precursor, increases NAD⁺levels and activatesSIRT1andSIRT3. Nicotinamide riboside is a source of vitamin B3 (niacin) and enhances oxidative metabolism, protection against high fat diet-induced metabolic abnormalities^[1]. Nicotinamide riboside reduces cognitive deterioration in a transgenic mouse model of Alzheimer’s disease^[2].

Nicotinamide riboside (0.5 nM; 24 hours) reduces the acetylation status of Ndufa9 and SOD2^[1].
Nicotinamide riboside increases intracellular and mitochondrial NAD⁺content in C2C12, Hepa1.6, and HEK293 cells in a concentration-dependent manner at concentrations ranging from 1-1000 μM^[1].
Nicotinamide riboside boosts NAD to restore antiviral poly(ADP-ribose) polymerase (PARP) functions to support innate immunity for coronavirus (CoVs), a cause of COVID-19^[3].

Chronic Nicotinamide riboside (p.o.; 400 mg/kg/day; for 16 weeks) supplementation increases plasma and intracellular NAD⁺content in a tissue-specific manner^[1].
