Nicotinamide Riboside Prevents Diabetic Cardiomyopathy: Preclinical Findings

Synopsis In a mouse model of diabetic cardiomyopathy (DCM) induced by STZ and a high-fat diet, nicotinamide riboside (NR) (400 mg/kg/day) lowered fasting glucose and insulin levels, improved diast...

Nicotinamide Riboside Prevents Oocyte Quality Loss in Maternal Diabetes: Preclinical Findings

Synopsis Diabetes reduces NAD+ levels in ovaries and oocytes, leading to poor oocyte quality, abnormal spindle formation, excess ROS, and impaired embryo development. In streptozotocin-induced dia...

Nicotinamide Riboside Restores Lipid Handling in Diabetic Heart Disease: Preclinical Findings

Synopsis Excessive lipid droplet buildup and lipotoxicity contribute to diabetic cardiomyopathy (DCM). This study found that lipophagy—the autophagic breakdown of lipid droplets—is impaired in DCM...

Nicotinamide Riboside Mitigates Diabetes-Related Bone Loss: Preclinical Findings

Synopsis Type 2 diabetes mellitus (T2DM) caused by high-fat diet/streptozotocin treatment led to impaired bone microarchitecture and bone loss in mice, along with metabolic dysfunction. Supplement...

Nicotinamide Riboside and Resveratrol Enhance Wound Healing in Diabetic Rats: Preclinical Findings

Synopsis Diabetes impairs wound healing by disrupting autophagy and promoting apoptosis. In a type 1 diabetic rat model, systemic and topical nicotinamide riboside (NR) and resveratrol (RSV) signi...

Nicotinamide Riboside and Resveratrol Promote Diabetic Wound Healing: Preclinical Findings

Synopsis Diabetic skin ulcers are difficult to treat and often lead to severe complications like infection or amputation. This study investigated how nicotinamide riboside (NR)—a vitamin B3–derive...

Nicotinamide Riboside and Nicotinamide Mononucleotide Restore Nerve Function in Diabetic Neuropathy: Preclinical Findings

SynopsisReduced NAD+ signaling contributes to nerve degeneration in diabetic peripheral neuropathy. Researchers tested NAD+ precursors, nicotinamide riboside and nicotinamide mononucleotide, in cul...

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 Improves Insulin Resistance by Boosting Mitochondrial Function in Skeletal Muscle: Preclinical Findings

SynopsisHigh-fat diet-induced insulin resistance (IR) in skeletal muscle is linked to mitochondrial dysfunction and oxidative stress. This study assessed whether nicotinamide riboside (NR) could re...

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 Supports Pancreatic β-Cell Function During Aging and Diet Stress: Preclinical Findings

SynopsisDisturbances in NAD+ metabolism have been linked to many age-related and metabolic diseases like type 2 diabetes. Pancreatic β-cells play a key role in controlling blood sugar, but how NAD+...

NAD+ Precursors Restore Mitochondrial Function and Prevent Nerve Damage in Diabetes: Preclinical Findings

SynopsisDiabetic peripheral neuropathy involves nerve degeneration linked to low NAD+ levels. Researchers tested whether NAD+ precursors nicotinamide mononucleotide (NMN) and nicotinamide riboside ...

Nicotinamide Riboside Restores Mitochondrial Balance and Protects the Diabetic Heart: Preclinical Findings

Synopsis In diabetes, heart damage often occurs because of mitochondrial imbalance, where the cell’s energy-producing structures become fragmented and dysfunctional. This study found that nicotina...

Nicotinamide Riboside Improves Wound Healing in Diabetes: Preclinical Findings

Synopsis Poor wound healing is a common complication of diabetes, largely due to impaired blood vessel formation. This study found that nicotinamide riboside (NR), a vitamin B3 derivative and NAD+...

NAD+ Precursors Improve Corneal Wound Healing and Nerve Regeneration in Diabetes: Preclinical Findings

Synopsis Nicotinamide adenine dinucleotide (NAD+) is a vital molecule that supports energy metabolism, cell repair, and tissue regeneration. In diabetes, chronically high blood sugar disrupts thes...

Nicotinamide Riboside Reduces Brain Inflammation and Improves Cognitive Function in Diabetic Mice: Preclinical Findings
