NAD+ (Nicotinamide Adenine Dinucleotide) is a naturally occurring coenzyme widely studied in laboratory settings for its fundamental role in cellular energy production, metabolic signalling and redox biology. As an essential molecule present in all living cells, NAD+ has become a key compound in research involving mitochondrial function, cellular metabolism and age-related biological processes.

In controlled research environments, NAD+ is commonly used in studies exploring mitochondrial bioenergetics, oxidative phosphorylation, DNA repair pathways, cellular signalling, redox homeostasis and metabolic regulation. Its well-characterised molecular structure and high purity make it suitable for advanced in-vitro applications requiring consistency, analytical reliability and reproducible research outcomes.
