NAD+ Peptide

NAD+ for Sale — 99% Research-Grade Coenzyme

NAD+ (Nicotinamide Adenine Dinucleotide) is the redox coenzyme at the centre of cellular energy transfer, sirtuin activity, and DNA-repair signalling. Paradigm Peptides supplies NAD+ at 99% purity for laboratory research only, tested by an independent third-party laboratory and shipped from the United States with certificate-of-analysis documentation available.

What researchers study it for

NAD+ cycles between its oxidised (NAD+) and reduced (NADH) states, accepting and donating electrons across glycolysis, the citric-acid cycle, and oxidative phosphorylation. That makes it a standard input in redox-biology work, mitochondrial-function and metabolic-rate studies, sirtuin and PARP activity assays, cellular-senescence and ageing models, and muscle-performance research. Availability of the oxidised form declines in many ageing models, which is why supplementation kinetics are a frequent subject of investigation.
