What is the Origin of NAD+ Metabolism Optimization?

The term is derived from the biochemical name of the molecule, NAD+, and the clinical goal of "optimization," reflecting a proactive approach to maintaining cellular health. Research into NAD+ and its precursors, such as Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN), has become a central pillar of modern longevity science following discoveries in the early 2000s.

What is the Mechanism of NAD+ Metabolism Optimization?

Optimization is mechanistically achieved by administering NAD+ precursors or compounds that inhibit NAD+-consuming enzymes like CD38 and PARPs. Once administered, precursors enter the cell and are converted into NAD+ via the salvage pathway. Elevated NAD+ levels then enhance the activity of sirtuins, which regulate gene expression, and poly(ADP-ribose) polymerases (PARPs), which are critical for DNA damage repair, collectively promoting cellular integrity and metabolic efficiency.

NAD+ Metabolism Optimization

Meaning

A targeted therapeutic strategy focused on increasing the cellular concentration and bioavailability of Nicotinamide Adenine Dinucleotide (NAD+), a crucial coenzyme involved in hundreds of essential metabolic reactions, including energy production and DNA repair. Optimization aims to counteract the age-related decline in NAD+ levels, thereby enhancing mitochondrial function, promoting cellular resilience, and supporting the activity of sirtuin longevity proteins.
