Understanding NAD+ and NMN: The Basics

The Role of NAD+ in Cellular Energy

One of the main functions of NAD+ is to facilitate the production of ATP (adenosine triphosphate), the primary energy source for cells. It acts as a cofactor in the electron transport chain, which is part of the process by which cells convert nutrients into energy. As we age, NAD+ levels naturally decline, which can lead to decreased energy production and slower cell regeneration.

What is NMN?

NMN (nicotinamide mononucleotide) is a precursor to NAD+, meaning that it’s a molecule that gets converted into NAD+ within the body. NMN is part of the NAD+ biosynthesis pathway, making it a critical player in maintaining or boosting NAD+ levels. Unlike direct NAD+ supplementation, which can be unstable and less efficient, NMN is more easily absorbed by cells and can effectively increase NAD+ levels.

NMN’s Role in Boosting NAD+

When NMN is introduced into the body, it undergoes a series of enzymatic reactions that lead to the production of NAD+. This process helps to replenish NAD+ levels, potentially offsetting the natural decline that comes with aging. By boosting NAD+, NMN supplementation may enhance cellular energy, support DNA repair, and improve overall cellular health.
