NMN and NAD: Double Stars of the Anti Aging

NAD (nicotinamide adenine dinucleotide) is a coenzyme widely present in organisms, playing a key role in multiple life processes such as energy metabolism, DNA repair, and cellular signaling. The presence of NAD is crucial for maintaining cellular health and bodily function.

The benefits of NAD

The benefits of NAD is mainly reflected in the following aspects:

Energy metabolism: NAD is the core molecule of intracellular energy metabolism, which participates in various enzymatic reactions, especially in mitochondria, helping cells convert food into energy.

DNA repair: NAD plays a crucial role in the DNA repair process, helping to maintain genomic stability and reduce the risk of mutations and damage.

Anti aging effect: The level of NAD is age-related, and it gradually decreases with age. Increasing NAD levels can delay the aging process and enhance the repair and regeneration ability of cells.

Neuroprotection: NAD has a protective effect on the nervous system, which can improve the health and function of neurons and help prevent and treat neurodegenerative diseases.


From which foods can NAD be obtained?

In fact, we cannot directly obtain NAD from food because NAD is synthesized within cells. However, we can indirectly increase NAD levels in the body by consuming foods containing NAD synthesis precursors. These precursors include niacin (vitamin B3), tryptophan, and NMN. Foods rich in these precursors include lean meat, fish, poultry, dairy products, legumes, and certain vegetables.


The similarities and differences between NMN and NAD


Common function: NMN, as a precursor of NAD, can be converted into NAD in vivo, thereby playing the role of NAD in energy metabolism, DNA repair, and other aspects.

Anti aging potential: NMN and NAD are both considered to have anti-aging potential, and by increasing intracellular NAD levels, they can help delay the aging process.


Chemical structure: NMN and NAD have different chemical structures. NMN is a simple precursor of NAD, which is converted into NAD through a series of enzymatic reactions in the body.

Existence form: NMN typically appears in the form of supplements or medications, requiring specific products for ingestion. NAD, on the other hand, is mainly synthesized within cells and cannot be directly obtained from food.

Absorption and utilization: NMN needs to undergo metabolism in the body after ingestion to be converted into NAD, and its absorption and utilization efficiency are influenced by various factors. NAD, on the other hand, is directly synthesized within cells and its level is regulated by multiple genes and metabolic pathways.
