NAD+ (Nicotinamide Adenine Dinucleotide) is a research-grade biochemical coenzyme commonly used in laboratory environments to study cellular energy metabolism, redox reactions, and enzymatic pathway activity. As a central molecule involved in oxidation–reduction processes, NAD+ is frequently examined for its role in mitochondrial function, metabolic signaling, and intracellular communication.

In scientific research, NAD+ is utilized in in vitro assays, cell culture studies, and mechanistic biochemical experiments to observe how metabolic cofactors influence enzyme behavior, energy-transfer pathways, and cellular response mechanisms under controlled laboratory conditions.

NAD+ is not intended for human or veterinary use. It is provided exclusively for laboratory research, analytical testing, and educational investigation, with no claims regarding biological effects or suitability for consumption.
