Collection: NAD+

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and central to cellular energy metabolism and redox biology. It is one of the most studied molecules in metabolic, mitochondrial, and aging research, where it functions in electron transfer, serves as a substrate for sirtuin and PARP enzyme families, and is examined in models of cellular energy balance and longevity. Its foundational role in metabolism makes it a frequent subject in both basic and applied research.

Each batch of NAD+ supplied by Ontario Peptide is verified through our three-stage standard — source-facility analysis, independent and community auditing, and our own final clearance including endotoxin testing — with results documented in a published Certificate of Analysis before dispatch.

We supply NAD+ in a 500 mg lyophilized presentation. Automatic bulk discounts apply at checkout, and all orders ship discreetly Canada-wide from within Ontario for fast, customs-free delivery.
