NMN, or nicotinamide mononucleotide, is a molecule found in cells that plays a critical role in energy metabolism, DNA repair and the maintenance of a healthy aging process. It functions by increasing the levels of NAD+ (nicotinamide adenine dinucleotide) in cells. NAD+ is a coenzyme that is essential for the proper functioning of many enzymes in the cell, including those involved in DNA repair, energy metabolism, and the regulation of the cell cycle.

As we age, NAD+ levels decline, which can lead to DNA damage, decreased energy production, and a decline in overall cellular function. Supplementation with NMN has been shown to increase NAD+ levels, which in turn can help protect cells from damage and promote longevity.

NMN has also been shown to have potential anti-aging effects on various organ systems. It has been shown to improve insulin sensitivity, and enhance muscle and bone health. Additionally, NMN has been shown to have a positive impact on the nervous system, including improving cognitive function and reducing the risk of neurodegenerative diseases.

However, more research is needed to fully understand the mechanisms and potential health benefits of NMN. The safety and efficacy of NMN supplements in humans has not yet been established, so it is important to consult a healthcare professional before taking any supplement.
