Nicotinamide Riboside Supplementation Combined with Metabolic Activators Improves Cognitive Function in Alzheimer’s Disease: Clinical Findings
Objectives
To investigate whether supplementation of combined metabolic activators (CMA) consisting of L-carnitine tartrate, nicotinamide riboside (NR), serine, and N-acetyl-L-cysteine (NAC), could affect the global metabolism and brain function of Alzheimer's disease (AD) patients and be used for treatment of the disease.
Journal
Translational Neurodegeneration
Key Outcomes
- CMA supplementation improved cognitive function by 29% in AD patients. Patients with high ADAS-Cog scores (worsened cognitive function) showed improvement with CMA supplementation.
- CMA also improved serum markers related to AD, as well as markers of liver and kidney health in AD patients, as seen through significant decreases in levels of alanine aminotransferase (ALT) and uric acid.
Duration
8 weeks
Dose

Study Design
