Nicotinamide Riboside Protects Against Liver Fibrosis: Preclinical Findings

Synopsis Nicotinamide riboside (NR) boosts NAD+ levels and offers protective effects in various diseases, but its role in liver fibrosis is unclear. This study tested NR’s ability to protect again...

Nicotinamide Riboside Protects Heart Function in Dilated Cardiomyopathy: Preclinical Findings

Synopsis In chronic heart failure, the heart’s energy metabolism is severely impaired. NAD+ is a key molecule that helps cells produce energy and respond to stress, making it an important focus in...

Nicotinamide Riboside Reduces Alcohol-Related Liver Damage: Preclinical Findings

Synopsis Alcohol causes liver damage by lowering the activity of SIRT1, a protein that regulates fat metabolism and mitochondrial function. Giving mice nicotinamide riboside (NR), an NAD+ precurso...

NAD+ Biosynthesis Enzyme Protects Aortic Smooth Muscle Cells: Preclinical Findings

Synopsis The walls of the aorta weaken with age and stress, risking serious damage. Smooth muscle cells (SMCs) in the aorta need NAD+, made by the enzyme NAMPT, for health. In humans with aortic d...

Nicotinamide Riboside Improves Alzheimer's Features and DNA Repair: Preclinical Findings

Synopsis Alzheimer’s disease (AD) involves problems with energy metabolism and DNA repair, but how these contribute to key AD features is unclear. A DNA repair-deficient AD mouse model (3xTgAD/Pol...

Nicotinamide Riboside Rejuvenates Aging Gut Stem Cells: Preclinical Findings

Synopsis Aging leads to tissue decline partly due to reduced function of adult stem cells. In the intestine, the number and activity of intestinal stem cells (ISCs) decrease with age, while Paneth...

Nicotinamide Riboside Reduces Brain Inflammation and Cellular Aging in Alzheimer’s Disease: Preclinical Findings

Synopsis In Alzheimer’s disease, brain cells often show low NAD+ levels, high inflammation, and impaired cellular cleanup of damaged components. In mice with Alzheimer’s-like brain changes, five m...

Nicotinamide Ribosides Improves Aerobic Performance: Preclinical Findings

Synopsis Nicotinamide riboside (NR) is a form of vitamin B3 that helps increase NAD+ and improve mitochondrial function, but its effect on physical fitness is unclear. In a study with sedentary an...

NAD+ Replenishment Prevents Thymus Atrophy and Liver Fat Accumulation: Preclinical Findings

Synopsis Dioxin (TCDD) is a highly toxic chemical that causes serious health problems like wasting, liver fat buildup, and thymus shrinkage in animals. Its toxic effects happen when it activates a...
