Nicotinamide mononucleotide (NMN) cas:1094-61-7 is a vital molecule in the body, playing a crucial role in the production of nicotinamide adenine dinucleotide (NAD+), an essential coenzyme involved in numerous cellular functions, including metabolism, DNA repair, and cell survival. As one of the primary precursors of NAD+, NMN helps maintain the energy balance and overall health of cells.

NMN, including its β-form (β-NMN), is derived from ribose, nicotinamide, and niacin. In humans, enzymes utilize NMN to generate NAD+, a molecule necessary for various cellular processes, such as mitochondrial function and gene expression. The conversion of NMN to NAD+ is particularly important for regulating energy production, DNA repair, and cellular health.

In animal models, particularly mice, NMN is absorbed rapidly through the small intestine, often within 10 minutes of oral intake. This fast absorption allows NMN to quickly increase NAD+ levels in the body. Once inside the cells, NMN is converted to NAD+ via the Slc12a8 transporter, which facilitates its entry.

Supplementing with NMN has shown potential benefits, such as improving mitochondrial function, enhancing DNA repair, reducing inflammation, and promoting overall cell survival. By boosting NAD+ levels, NMN can help address age-related cellular decline, supporting healthier aging and improved metabolic health.

Overall, NMN plays a vital role in maintaining cellular functions and promoting longevity, making it a promising compound for supporting health and combating age-related diseases.
