Nicotinamide riboside malate is an orally active NAD+ precursor that elevates NAD+ levels and stimulates the activity of SIRT1 and SIRT3. Functioning as a vitamin B3 (niacin) source, it augments oxidative metabolism and provides protection against metabolic abnormalities induced by a high-fat diet. Additionally, Nicotinamide riboside malate mitigates cognitive decline in a genetically modified mouse model of Alzheimer's disease.

Nicotinamide riboside malate (0.5 nM; 24 hours) reduces the acetylation status of Ndufa9 and SOD2[1]. Nicotinamide riboside malate 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 malate boosts NAD to restore antiviral poly(ADP-ribose) polymerase (PARP) functions to support innate immunity for coronavirus (CoVs), a cause of COVID-19[3]. Western Blot Analysis[1]Cell Line: HEK293T cells Concentration: 0.5 nM Incubation Time: 24 hours Result: Reduced the acetylation status of Ndufa9 and SOD2.

Chronic Nicotinamide riboside malate (p.o.; 400 mg/kg/day; for 16 weeks) supplementation increases plasma and intracellular NAD + content in a tissue-specific manner[1]. Animal Model: 10-week-old C57Bl/6J mice[1]Dosage: 400 mg/kg Administration: PO; daily; for 16 weeks Result: Increased plasma and intracellular NAD + content in a tissue-specific manner.
