Frequently asked questions (FAQs)
FAQs About NMN?
Q1. How does NMN anti-aging?
NMN is classified as a dietary supplement and cannot replace medication. After NMN is converted to NAD+ in the body, it plays a role in activating longevity proteins, repairing DNA, promoting cellular energy production, regulating the biological clock, improving sleep, enhancing physical fitness, and lowering blood sugar levels.
Q2. Where are the differences between NAD and NMN?
NMN is a precursor to NAD, playing a crucial role in replenishing cellular NAD levels. NAD, on the other hand, directly participates in cellular energy metabolism and various biological processes. NMN can be taken orally as a supplement, while NAD is typically not administered directly due to limited bioavailability.
Q3. Where are the differences between NR and NMN?
Research has explored the efficacy of both NR and NMN in enhancing NAD+ levels. In an interview with Harvard genetics professor David Sinclair, he mentioned his preference for NMN over NR. In experiments, NMN supplementation led to older mice running 50% further due to improved blood flow and energy. Interestingly, supplementing with NR at the same dosage did not yield the same positive outcome observed with NMN. Further details on the disparities between the two can be found in the referenced article.
Q4. Is NMN better than NR?
It appears likely that NMN holds an advantage over NR in the pathways converting NAD boosters (such as NMN and NR) into NAD, coupled with its greater stability in the bloodstream. Scientific studies suggest that NMN outperforms NR in various aspects. For instance, NMN demonstrates more favorable effects on aging symptoms compared to NR, and individuals often report experiencing greater benefits with NMN. However, NR is currently receiving significant promotion, sometimes overshadowing NMN. One contributing factor is that the production process of NR is patented, leading to a monopoly held by specific companies that aggressively market NR. In contrast, NMN lacks patent protection, resulting in less aggressive marketing of this molecule.

In 2017, Dr. David Sinclair, a professor at Harvard Medical School, received a major award for his groundbreaking solution to a biological problem. His solution involved using NMN, a precursor to NAD+, which can directly repair DNA damage caused by radiation exposure or aging. When mice were treated with NAD+ and NMN, they showed a significant improvement in their ability to repair DNA damage caused by radiation exposure or aging.
This discovery was so significant that even NASA decided to use NMN, a precursor to NAD+, to help protect against radiation. Radiation is a concern not only for astronauts but also for various professionals exposed to radiation, such as laboratory workers, at-risk engineers, pilots, flight attendants, frequent travelers, and outdoor workers. They actively supplement with NAD+ to resist the effects of aging and the risks associated with radiation exposure.
Q11. Can NMN help protect the liver from alcohol?
Yes, NMN can promote alcohol metabolism and enhance the body's tolerance to alcohol.
Q12. Can NMN protect hearing?
Yes, NMN increases NAD+ levels in ear neurons and tissues, providing protection against hearing loss caused by trauma.
Q13. Why is there such a significant price difference for NMN?
The price difference in NMN products primarily depends on the total NMN content in each bottle. For instance, if a bottle contains 60 capsules, and each capsule has 50mg of NMN, then the total NMN content in that bottle is 50mg * 60 capsules = 3000mg. So, it is labeled as NMN3000. Similarly, if each capsule contains 330mg of NMN, then the total content in a bottle is 330mg * 60 capsules = 19800mg, and it is labeled as NMN19800. The number following NMN represents the total content in each bottle.
Q14. What role does NMN play in supporting DNA repair mechanisms within cells?
NMN supports DNA repair indirectly by replenishing cellular NAD+ levels. NAD+ is a critical coenzyme involved in various cellular processes, including DNA repair mechanisms such as base excision repair and DNA strand break repair. By providing a precursor for NAD+ synthesis, NMN ensures an ample supply of NAD+ within cells, which in turn supports efficient DNA repair processes, helping to maintain genomic stability and integrity.
Q15: How does NMN contribute to increasing cellular energy levels within the body?
NMN boosts energy levels by serving as a precursor to NAD+ synthesis. NAD+ is a coenzyme involved in cellular metabolism, particularly in the production of ATP, the primary energy currency of cells. By replenishing NAD+ levels, NMN supports efficient energy production processes, leading to enhanced cellular energy levels.
