NAD-Related Compounds Affect Immune Cell Growth and Inflammatory Response: Preclinical Findings

Synopsis Nicotinamide (NAM), nicotinamide riboside (NR), and 1-methylnicotinamide (MNA) are compounds related to NAD+ that play important roles in cell signaling, including in the immune system. S...

Mild Vitamin B3 Deficiency Changes Gene Activity in White Fat Tissue: Preclinical Findings

Synopsis Mild vitamin B3 (niacin) deficiency is hard to detect. This study compared mice fed a diet without NR (vitamin B3 precursor) to those given recommended B3 levels, both with low tryptophan...

Nicotinamide Riboside Demonstrates Cardioprotective Effects by Boosting Mitochondrial Stress Response: Preclinical Findings

Synopsis The mitochondrial unfolded protein response (UPRmt) helps cells manage misfolded proteins in mitochondria to maintain function. Cardiac mitochondria are essential for contractile function...

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 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...

Muscle Loss and Reduced Physical Performance in Emery–Dreifuss Muscular Dystrophy: Preclinical Findings

Synopsis Autosomal Emery–Dreifuss muscular dystrophy (EDMD) is caused by mutations in the lamin A/C gene (LMNA), which encodes nuclear envelope proteins. The disease typically causes muscle wastin...

Nicotinamide Riboside Enhances Blood Stem Cell Recovery and Regeneration: Preclinical Findings

Synopsis Recent studies show that increased mitochondrial activity and impaired stress response harm hematopoietic stem cells (HSCs), reducing their ability to regenerate. This study found that NR...

Nicotinamide Riboside Protects Motor Neurons in ALS: Preclinical Findings

Synopsis Sirtuins (SIRTs) are enzymes that rely on NAD+ and help regulate DNA repair, metabolism, and oxidative stress. Boosting NAD+ levels can activate SIRTs and antioxidant proteins, reducing m...

Measuring NAD+ Levels in Blood, Muscle, and Cerebrospinal Fluid: Preclinical Findings

SynopsisThe balance between NAD+ and NADH is vital for cell health, aging, and disease. However, accurately measuring NAD+ and its related metabolites is difficult because reduced forms like NADH a...

Nicotinamide Riboside Prevents Gut Damage After Ischemia: Preclinical Findings

Synopsis Acute mesenteric ischaemia happens when blood flow to the intestines is blocked, which can cause tissue damage and even gangrene. This condition is rare but can be life-threatening. Besid...

Measurement of NAD+ Precursors, Including Nicotinamide Riboside, in Human Milk: Preclinical Findings

Synopsis B-vitamins are essential for infant growth and metabolism, and vitamin B3 (niacin)—including nicotinamide (NM) and nicotinic acid (NA)—serves as a precursor for the coenzyme NAD+, which i...

Neonatal Resveratrol and Nicotinamide Riboside Supplementation Increase Energy-Burning Fat Development: Preclinical Findings

Synopsis Early nutrition can influence how fat cells develop and function later in life, impacting metabolism and long-term health. This study explored how early-life supplementation with nicotina...
