What Is NAD+?

NAD+ is a coenzyme / dinucleotide supplied by Peptegrity for research and educational purposes. This page provides a factual educational overview of NAD+, including its classification, biological target, research background, terminology and published study context. It is not a product page and does not provide dosing instructions, treatment recommendations or personal-use guidance.

Type of compound

NAD+ (Nicotinamide adenine dinucleotide) is a coenzyme found in all living cells, classified as a dinucleotide. It plays a critical role in metabolic redox reactions by transferring electrons between molecules.

Biological target and mechanism

NAD+ functions as a coenzyme in catabolic processes, including glycolysis, the TCA cycle, and mitochondrial oxidative phosphorylation [1]. It acts as a substrate for enzymes like PARPs, sirtuins, and CD38, which are involved in DNA repair and the regulation of cellular homeostasis [4].

Research background

Research into NAD+ is primarily focused on its decline during biological aging and its subsequent impact on cellular metabolism [3]. Scientists investigate how fluctuations in NAD+ levels influence mitochondrial function and the aging process in various tissue types [1, 4].

Current research and development status

NAD+ is currently an investigational molecule being studied in basic science and preclinical models. It is not an approved medication for the treatment or prevention of any human disease.

Published research context

Published literature examines the intricate pathways of NAD+ biosynthesis, salvage, and consumption within the human body [3, 4]. Recent research also explores how various nutritional boosters impact circulatory NAD+ concentrations and the influence of microbial metabolism on these pathways [2].

Relevant terminology

NAD+ stands for nicotinamide adenine dinucleotide, a molecule essential for energy metabolism. Redox refers to reduction-oxidation reactions where electrons are transferred, which is a fundamental process in cellular respiration.

Storage and handling terminology

In laboratory research settings, NAD+ should typically be stored at low temperatures, such as -20°C or -80°C, to maintain structural stability. It is sensitive to light, moisture, and temperature fluctuations, requiring careful handling in a controlled environment.

Testing and Certificate of Analysis (COA)

A Certificate of Analysis (COA) is a document issued by a laboratory or manufacturer that confirms the purity and identity of a research chemical. For high-quality research, investigators rely on COAs provided by analytical laboratories utilizing methods like High-Performance Liquid Chromatography (HPLC) or Nuclear Magnetic Resonance (NMR) spectroscopy.

Regulatory status

NAD+ is classified as a research compound and is not approved by regulatory agencies like the FDA or TGA for human therapeutic use. It is strictly available for laboratory, industrial, or experimental research purposes.
