NMN and NAD differences between them?

What are NMN and NAD?

NAD: Nicotinamide adenine dinucleotide. NAD has two different molecular structures: NAD+ and NADH.

Nicotinamide mononucleotide (NMN) and nicotinamide adenine dinucleotide (NAD+) are closely related molecules that are involved in numerous molecular events such as DNA repair, cellular metabolism, and energy production.

Specifically, NMN is a precursor of NAD+, which subsequently drives these molecular processes.

NMN has been proposed to have anti-aging properties because it can increase the NAD+ level in the body.

With the increase of age, the level of NAD+ continues to decline.

The depletion of NAD+ is related to the occurrence of aging-related functional disorders and diseases.

Many people are exploring ways to increase their own NMN or NAD+ levels.

core functions of NMN and NAD+

1. benefits of NMN

NMN is a direct precursor of NAD+, and its core function is to indirectly affect cell function by increasing NAD+ levels.

Anti-aging: Activate longevity proteins Sirtuins (SIRT1-SIRT7) to delay cellular aging.
nce metabolism: Promote mitochondrial function, increase ATP energy production, and alleviate fatigue.
iring DNA: Supports PARP enzyme activity and reduces DNA damage caused by oxidative stress.
late the biological clock: Optimize the circadian rhythm and improve sleep quality.
ecting the cardiovascular system: Enhancing vascular elasticity and reducing the risk of arteriosclerosis.

2. main functions of NAD+

NAD+ is the "energy currency" of cells and directly participates in key biochemical reactions:

Energy metabolism: As a coenzyme, it participates in the decomposition of sugar, fat and protein (TCA cycle, oxidative phosphorylation).
Activate Sirtuins: Regulate gene expression and extend cell lifespan.
DNA repair: Provides substrates for PARP enzymes and maintains genomic stability.
Antioxidant: By regulating the REDOX balance, it reduces free radical damage.
Neuroprotection: Supports brain cell function and potentially improves neurodegenerative diseases such as Alzheimer's disease.
