What is the difference between NMN and NAD

If you came to this blog, it is because you have been wondering about those mysterious particles that are responsible for essential biological processes: NAD vs NMN

NAD (nicotinamide adenine dinucleotide) and NMN (nicotinamide mononucleotide) have become relevant terms when talking about longevity and overall health. But are they similar or even the same? In this blog we will delve into their differences, functions and the advantages they have for you. 

What is NAD?

It is also known as nicotinamide adenine dinucleotide. NAD is a coenzyme found in all cells in our body. It is a key component for metabolic processes that contributes to the following processes:

  • Energy production
  • DNA repair 
  • General maintenance of cellular functioning

NAD is crucial for keeping cells "breathing" at a normal rate. Meaning that it allows vital nutrients to be transformed into energy used in the form of adenosine triphosphate (ATP). Therefore, it plays an influential role in improving the precision of genetic material by participating in DNA repair functions. As a result, its presence and subsequent functioning become necessary elements for the adequate health of organisms, as well as the effective execution of all biological activities.

Why is NAD important for the human body?

NAD is a vital coenzyme found in all cells and performs various functions. It's essential for energy production, participating in cellular respiration and the synthesis of ATP.

NAD also regulates metabolism by interacting with sirtuins, enzymes that influence genetic expression and metabolic pathways.

It plays a crucial role in DNA repair and maintenance by supporting the activity of PARP enzymes. Additionally, it contributes to cellular defense against oxidative stress, acts as a signaling molecule in various pathways, and functions as an electron carrier in redox reactions.

As you can see, the presence and proper functioning of NAD is crucial for a variety of biological processes, as well as optimal health.

What is NMN?

NMN is a natural molecule that is classified as a bioactive nucleotide. It is a precursor of nicotinamide adenine dinucleotide (NAD+), which is a compound located in every cell in the body. 

NAD+ participates in important cellular processes such as energy metabolism, DNA repair and the regulation of mitochondrial function. 

There are those who take NMN supplements in hopes of increasing NAD+ levels and improving their health. It is possible to find it in a natural diet, in small quantities, in various food sources, both animals and plants (broccoli, avocados, cucumbers, etc).

How does a NMN supplement help you?

NMN, when administered as a dietary supplement, may help suppress age-related weight gain. It is also helpful in improving energy metabolism and physical activity. This not only affects physical activity, but also genetic pathways that essentially regulate the processes in the body related to aging.

This is why NMN is commonly dubbed as the "limitless pill"; the fountain of youth in a bottle.


NAD supplements and NAD precursors with different characteristics and implications. NAD precursors, such as NMN, can be converted to NAD within the body. 

Speaking of the specific case of NMN, it is recognized as a notable precursor of NAD. Once it is consumed, it undergoes specific enzymatic reactions that allow it to be transformed into NAD.
