NMN and NAD differences between them?

What are NMN and NAD?

NMN: Nicotinamide Mononucleotide

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. n 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.
