NAD+

Overview

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. It exists in two forms: an oxidised form (NAD+) and a reduced form (NADH). The ratio between these forms is a central regulator of cellular energy metabolism and has been the subject of decades of published biochemistry research.

Role in Cellular Metabolism

NAD+ is an essential cofactor for three major classes of enzymes studied in the published literature:

Sirtuins (SIRT1-7) — a family of NAD+-dependent deacetylases investigated for their roles in gene expression regulation, DNA repair pathway research, and mitochondrial function studies

Poly(ADP-ribose) polymerases (PARPs) — enzymes involved in DNA damage response research

CD38/CD157 — ectoenzymes studied in calcium signalling and immune cell research

Published research in cell culture and animal models has characterised how NAD+ availability influences the activity of these enzyme families and their downstream effects on cellular metabolism.

Preclinical Research

Published preclinical studies have explored NAD+ in the context of:

Mitochondrial function and biogenesis research in rodent models

Sirtuin pathway activation studies

DNA repair mechanism research

Cellular senescence marker studies

Metabolic pathway research in models of metabolic dysfunction

Circadian rhythm regulation research

These studies are preclinical in nature. Clinical translation to humans remains an active area of investigation and NAD+ is not approved by the TGA for any therapeutic indication.

Quality and Verification

Every batch ships with a batch-specific Certificate of Analysis documenting purity verification. The product is shipped lyophilised to preserve stability during transit and should be stored at -20 degrees Celsius prior to reconstitution and 2-8 degrees Celsius after reconstitution in the laboratory.
