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...

Nicotinamide Riboside Prevents and Reverses Chemotherapy-Induced Peripheral Neuropathy: Preclinical Findings

Synopsis Damage to sensory nerves can cause peripheral neuropathy after chemotherapy. Increasing levels of nicotinamide adenine dinucleotide (NAD+) can protect nerves from injury. This study teste...

Nicotinamide Riboside Dose Improves Metabolic Flexibility: Preclinical Findings

SynopsisMetabolic flexibility—the ability to switch between burning carbs and fats—is a marker of metabolic health. To study NR's effect on this, mice on a mildly obese diet received varying NR dos...

NMN Converts to Nicotinamide Riboside Before Entering Cells: Preclinical Findings

SynopsisNAD+ is an essential molecule that helps enzymes like sirtuins and poly(ADP-ribose) polymerases work properly. Supplements like nicotinamide mononucleotide (NMN) and nicotinamide riboside (...

Nicotinamide Riboside Reduces Liver Inflammation and DNA Damage: Preclinical Findings

Synopsis Obesity increases the risk of liver cancer (hepatocellular carcinoma, HCC), but the exact mechanisms were unclear. This study found that a liver protein called URI links excess nutrients ...

Nicotinamide Riboside Protects Against Diabetes and Neuropathy: Preclinical Findings

SynopsisMale C57BL/6J mice fed a high-fat diet (HFD) develop prediabetes with insulin resistance and sensory neuropathy. When given low doses of streptozotocin, these mice model type 2 diabetes (T2...

Nicotinamide Riboside Is a Key NAD+ Precursor in Cow's Milk: Preclinical Findings

Synopsis Nicotinamide riboside (NR) is a recently identified form of vitamin B3 that serves as a natural precursor to NAD+, a vital molecule for energy production and cellular repair. While NR was...

Nicotinamide Ribosides Reverses Fatty Liver Disease: Preclinical Findings

Synopsis Nonalcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease, with no approved drug treatments. This study demonstrates that a high-fat, high-sugar diet reduces ...

NAD+ in Aging, Metabolism, and Neurodegeneration: Review

SynopsisNAD+ is a coenzyme essential for energy production, redox reactions, and as a partner for enzymes like sirtuins and PARPs. Its levels change with age, and altering its production or usage c...

Nicotinamide Riboside Reduces Inflammation and Supports Mitochondrial Health: Preclinical Findings

Synopsis Activation of the NLRP3 inflammasome, a key driver of inflammation linked to metabolic dysfunction, can be influenced by nutrient levels and mitochondrial health. In a study of healthy vo...

Nicotinamide Riboside Reduces Liver Inflammation in Diabetes: Preclinical Findings

Synopsis Chronic low-grade inflammation—known as metaflammation—is a key driver of conditions like type 2 diabetes, obesity, and cardiovascular disease. This study investigated whether nicotinamid...

A High-Fat Diet and Increasing NAD+ Rescues Premature Aging in Cockayne Syndrome: Preclinical Findings

Synopsis Cockayne syndrome (CS) is a rare genetic disorder that causes early aging and progressive brain degeneration due to problems in DNA repair genes (CSA or CSB). In mice with the CSB mutatio...

NAD+ Metabolism as a Therapeutic Target for Age-Related Metabolic Diseases: Review

SynopsisNAD+ is a central redox cofactor, but its role in activating sirtuins—a family of NAD-dependent proteins that optimize mitochondrial function—has made it a focus of longevity research. Beca...

Nicotinamide Riboside Protects Against High-Fat Diet-Induced Obesity: Preclinical Findings

Synopsis NAD+ is a crucial molecule required for the activity of sirtuin enzymes, which regulate energy use and cellular health. Because of this, adjusting NAD+ levels has become an important way ...
