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

Synopsis

The 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. This study tested whether changes in gut bacteria contribute to NR's effects. Mice given NR had altered gut microbes, with more butyrate-producing bacteria linked to energy metabolism. Transferring feces from NR-treated mice to other obese mice reduced weight gain and boosted energy use. These findings suggest NR benefits partly come from changes in gut bacteria, which might enhance NR's therapeutic effects against obesity and related diseases.

NAD+ Supports Metabolism in Impaired Urea Cycle: Preclinical Findings

SynopsisProblems in the urea cycle and how they relate to obesity and inflammation are not well understood, partly because classical urea cycle defects are severe and dramatic. To study this, resea...
