Nicotinamide Riboside Protects Retinal Nerve Cells in Glaucoma: Preclinical Findings

SynopsisGlaucoma causes progressive retinal ganglion cell (RGC) degeneration and vision loss, often associated with elevated intraocular pressure (IOP). This study tested whether oral administratio...

Nicotinamide Riboside Protects Mitochondria in Aging Kidneys: Preclinical Findings

SynopsisAs kidneys age, their cells, especially in the distal tubules, undergo changes in mitochondrial structure and function, but little is known about how aging or anti-aging interventions affec...

Nicotinamide Riboside Protects Liver Immune Cells from Alcohol-Induced Damage: Preclinical Findings

SynopsisAlcohol-related liver disease (ALD) is linked to mitochondrial dysfunction and impaired energy metabolism. This study examined how ethanol damages Kupffer cells, the liver's resident immune...

Nicotinamide Riboside Protects Kidneys after Heart Attack: Preclinical Findings

SynopsisCardiorenal syndrome type 1 occurs when acute kidney injury (AKI) develops after sudden heart problems like a heart attack (MI), increasing the risk of death. This study tested whether nico...

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 Protects Gut Nerve Health and Improves Gastrointestinal Transit in Diabetes: Preclinical Findings

SynopsisDiabetes causes systemic oxidative stress that often leads to nerve damage in the enteric nervous system, impairing gut motility and causing symptoms such as constipation or diarrhea. Using...

Nicotinamide Riboside Protects CD8+ T Cells From Exhaustion by Improving Mitochondrial Health: Preclinical Findings

SynopsisProtecting mitochondria in CD8+ T cells is important for improving cancer immunotherapy. This study tested whether nicotinamide riboside (NR) could prevent T cell exhaustion. In lab models,...

Nicotinamide Riboside Protects Against Diabetic Kidney Disease: Preclinical Findings

SynopsisDiabetic kidney disease (DKD) is a leading cause of kidney failure, linked to inflammation and mitochondrial dysfunction. This study evaluated whether boosting NAD+ metabolism via nicotinam...

Nicotinamide Riboside Protects Against Light-Induced Retinal Degeneration: Preclinical Findings

SynopsisRetinal diseases cause a decline in nicotinamide adenine dinucleotide (NAD+), a vital coenzyme for cellular energy and biosynthesis, which may contribute to retinal damage. This study teste...

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 Protects Against Chronic Kidney Disease by Boosting Metabolism: Preclinical Findings

SynopsisChronic kidney disease (CKD) impairs kidney metabolism, including fatty acid breakdown, and is linked to low NAD+ levels. This study tested nicotinamide riboside (NR), a precursor of NAD+, ...

Nicotinamide Riboside Prevents Muscle Fatigue in Pigs: Preclinical Findings

SynopsisThis study tested how different doses of nicotinamide riboside (NR) affect muscle fatigue in pigs. One hundred barrows were fed diets with 0, 15, 30, or 45 mg NR per kg of body weight, or g...

Nicotinamide Riboside Prevents Low Kidney Nephron Numbers Caused by Maternal Protein Restriction: Preclinical Findings

SynopsisBabies born with fewer nephrons (kidney filters), often due to poor maternal nutrition, have higher risk for kidney disease and high blood pressure later. There are no current treatments to...

Nicotinamide Riboside Prevents Liver Injury and Restores Mitochondrial Function: Preclinical Findings

SynopsisNAMPT is an enzyme that helps make NAD+. Since low liver NAD+ is linked to fatty liver disease, scientists removed NAMPT specifically from liver cells in mice to see the effect. These mice ...

Nicotinamide Riboside Prevents Age-Related Hearing Loss: Preclinical Findings

SynopsisAge‐related hearing loss (ARHL) is the most common sensory disability associated with human aging. Yet, there are no approved measures for preventing or treating this debilitating condition...

Nicotinamide Riboside Preserves Retinal Cells and Mitochondrial Function in Glucocorticoid-Induced Glaucomae: Preclinical Findings

SynopsisGlucocorticoid-induced glaucoma (GIG) is a common side effect of steroid use that can cause blindness by damaging the eye's trabecular meshwork (TM), raising eye pressure, and killing retin...

Nicotinamide Riboside Increases Stress Sensitivity and Alters Blood Cell Composition in Aging: Preclinical Findings

SynopsisNicotinamide riboside (NR) is a precursor to NAD⁺, a key molecule for cellular energy that declines with age. Aging can cause reduced brain and immune function, changes in blood, and greate...
