What is NAD+?

Nicotinamide adenine dinucleotide (NAD+) is a naturally occurring coenzyme present in virtually every cell of the body.

Unlike signalling peptides, NAD+ functions as an essential coenzyme that participates in hundreds of biochemical reactions, particularly those involved in converting nutrients into usable cellular energy.

Researchers have studied NAD+ for decades because of its central role in mitochondrial biology, metabolism, DNA repair, and cellular physiology.

How Does NAD+ Work?

NAD+ acts as an electron carrier during numerous metabolic reactions, allowing cells to efficiently produce energy.

Current research continues to investigate its involvement in several biological processes, including:

Cellular energy production
Mitochondrial function
Oxidative metabolism
DNA repair pathways
Cellular signalling
Redox balance

These mechanisms remain an active area of biochemical and physiological research.

Why is NAD+ Important?

Every cell relies on NAD+ to support essential metabolic functions.

Researchers continue to investigate how NAD+ contributes to:

ATP production
Mitochondrial health
Cellular metabolism
DNA maintenance
