Nicotinamide Riboside Restores Intestinal Health and Mitochondrial Function in Colitis: Preclinical Findings

SynopsisReduced levels of PGC1α, a key regulator of cellular energy, contribute to inflammatory bowel disease (IBD). In both mice with experimental colitis and humans with ulcerative colitis, NAD+ ...

Nicotinamide Riboside Restores Gut Microbiota Diversity and Composition in Alzheimer's Disease

SynopsisAlzheimer's disease (AD) is associated with gut microbiota imbalances. In APP/PS1 transgenic AD mice, gut microbiome diversity was reduced and composition altered compared to wild-type mice...

Nicotinamide Riboside Protects Intestinal Barrier From Alcohol Damage by Supporting Mitochondrial Function: Preclinical Findings

SynopsisThe intestinal barrier, made up of epithelial tight junctions, prevents harmful substances in the gut from entering the bloodstream. When this barrier is damaged, it can cause widespread in...

Nicotinamide Riboside and Metabolic Cofactors Improve Gut Health in Fatty Liver Disease: Preclinical Findings

SynopsisThe gut barrier controls what passes into the body and protects organs like the liver. An unhealthy diet and lifestyle cause gut microbiome imbalances (dysbiosis) and gut barrier damage, wh...

Nicotinamide Riboside and Derivatives Alter Intestinal Membrane Function and Gut Microbiome: Preclinical Results

SynopsisResearchers synthesized two new nicotinamide riboside (NR) derivatives—one water-soluble and one oil-soluble—and tested them alongside NR in chick embryos. NR and derivatives altered intest...

Nicotinamide Riboside and Calorie Restriction Improve Gut Microbiota and Reduce Liver Fat and Inflammation: Preclinical Findings

SynopsisMetabolic dysfunction–related fatty liver disease currently has no specific therapy. This study tested nicotinamide riboside (NR) and dietary restriction (DR) in rats with diet-induced obes...

Nicotinamide Riboside Alters Gut Microbiota to Reduce Weight Gain from High-Fat Diet in Mice: Preclinical Findings

SynopsisThe gut microbiome influences energy balance and obesity risk. Nicotinamide riboside (NR), a vitamin B3 form and NAD+ precursor, can reduce weight gain and increase energy use in obese mice...

Nicotinamide Riboside Supplementation May Influence Bacterial Composition: Clinical Findings

Objectives To explore the effects of NR supplementation on the gut microbiota composition in humans. Journal npj Aging Key Outcomes NR supplementation did not affect the diversity or abundance of ...

Nicotinamide Riboside Supplementation Increases Muscle Mitochondrial Biogenesis & Gut Health: Clinical Findings

Objectives To investigate the effects of long-term NR supplementation on mitochondrial biogenesis and metabolic health in humans. Journal Science Advances Key Outcomes In the BMI-discordant twi...
