NAD+

NAD+ Metabolism and Its Roles in Cellular Processes During Ageing Nature Reviews Molecular Cell Biology Seminal review examining NAD+ as a central redox cofactor in 500+ enzymatic reactions, detailing how age-related NAD+ decline drives senescence, genomic instability, and metabolic dysfunction. Cited for scientific context only; findings are from preclinical and in vitro models.

NAD+ Metabolism in Cardiac Health, Aging, and Disease Circulation Abdellatif M, Sedej S, Kroemer G. Review describing how NAD+ pools decline with aging, obesity, and hypertension in preclinical models. Experimental NAD+ elevation via precursor supplementation modulated cardiomyopathy-associated markers and NAD+-dependent enzyme activity across multiple preclinical cardiomyopathy models. Cited for scientific context only; does not provide use guidance for this research compound.

Nicotine Rebalances NAD+ Homeostasis and Improves Aging-Related Symptoms in Male Mice by Enhancing NAMPT Activity Nature Communications Yang L et al. Preclinical study demonstrating that NAD+ salvage pathway activation via NAMPT deacetylation — independent of nicotinic acetylcholine receptors — restored age-related NAD+ decline and modulated cellular energy metabolism markers in murine models. Cited for scientific context on NAD+ salvage pathway signaling only.

Cellular NAD Replenishment Confers Marked Neuroprotection Against Ischemic Cell Death: Role of Enhanced DNA Repair Stroke Wang S et al. NAD+ supplementation conferred neuroprotection against oxygen-glucose deprivation-induced cell death in vitro through enhanced base-excision DNA repair capacity — specifically AP endonuclease and DNA polymerase-beta activity — and reduction of cytotoxic DNA lesion accumulation.

Chronic Nicotinamide Riboside Supplementation Is Well-Tolerated and Elevates NAD+ in Healthy Middle-Aged and Older Adults Nature Communications Martens CR et al. Pharmacokinetic and biomarker study describing nicotinamide riboside effects on circulating NAD+ pathway metabolite levels and vascular signaling readouts. Cited for scientific context on NAD+ precursor pharmacology only; it does not provide use guidance or product claims for this research compound.

NAD+ Repletion Rescues Female Fertility during Reproductive Aging Cell Reports Bertoldo MJ et al. NMN-mediated NAD+ repletion in aged mice improved oocyte quality and ovulation rates to levels comparable to young controls via SIRT2-dependent mechanisms, implicating NAD+ decline in age-related reproductive biology pathway dysregulation. Cited for scientific context only; findings are from preclinical animal models.
