Nicotinamide mononucleotide (NMN) is a naturally occurring molecule that is found in all living cells. It is a precursor to nicotinamide adenine dinucleotide (NAD+), a coenzyme that plays a vital role in many cellular processes, including energy metabolism, DNA repair, and cell signaling. NAD+ levels decline with age, which is thought to contribute to a variety of age-related diseases and conditions. NMN supplements are becoming increasingly popular as a way to boost NAD+ levels and improve overall health and longevity.
Structure of NMN
NMN is a ribonucleotide, meaning that it is made up of a ribose sugar, a phosphate group, and a nitrogenous base. The nitrogenous base in NMN is nicotinamide (NAM).
The structure of NMN is shown below:

NMN and NAD+
NMN is converted to NAD+ in the body by the enzyme NMNAT. NAD+ is a cofactor for many enzymes, meaning that it is necessary for these enzymes to function properly. NAD+ is involved in a wide range of cellular processes, including:
- Energy metabolism: NAD+ is essential for the production of ATP, the body’s main energy currency.
- DNA repair: NAD+ is involved in the repair of DNA damage, which helps to protect cells from cancer and other diseases.
- Cell signaling: NAD+ is involved in a variety of cell signaling pathways, which regulate cell growth, differentiation, and survival.
NMN and aging
NAD+ levels decline with age, which is thought to contribute to a variety of age-related diseases and conditions. NMN supplements can help to boost NAD+ levels and protect against the damage that is caused by NAD+ deficiency.
Potential benefits of NMN supplementation
NMN supplementation has been shown to have a number of potential benefits, including:
- Increased energy levels and endurance
- Improved cognitive function
- Reduced risk of age-related diseases, such as Alzheimer’s disease, Parkinson’s disease, cardiovascular disease, and cancer
- Increased lifespan
Safety and side effects of NMN supplementation
NMN supplementation appears to be safe for most people. However, some people may experience mild side effects, such as nausea, diarrhea, and headache.
It is important to note that NMN research is still in its early stages, and more research is needed to confirm the long-term safety and efficacy of NMN supplementation.
