NMN (Nicotinamide Mononucleotide) is a substance similar to vitamin B3, which can produce NAD+ (a key metabolic intermediate) in the body. Therefore, studies have shown that NMN may help improve aging-related health issues such as metabolism, immunity, cell repair, brain health, and more.
Currently, NMN supplements are mainly used to treat the following diseases:
Aging-related metabolic disorders such as diabetes, obesity, high cholesterol, etc.
Aging-related neurodegenerative diseases, such as Alzheimer's disease.
Aging-associated immune decline.
Aging-related cardiovascular disease.
NMN supplements are mainly used to increase NAD+ levels to improve metabolic diseases and slow down the aging process.
Improve metabolic diseases: Studies have shown that NMN can improve the symptoms of metabolic diseases such as diabetes, fatty liver and obesity.
Delay the aging process: NMN can increase the vitality of cells, improve the metabolic process of cells, and delay the aging process.
Protect DNA: NAD+ is an important metabolic substance in cells and participates in various biological processes such as cellular energy metabolism and DNA repair. Supplementing NMN can increase NAD+ levels and protect DNA.
Improves Athletic Capacity: NMN has been shown to improve athletic performance and increase fat burning ability
Improve neurodegenerative diseases: Studies have shown that NMN can improve neurodegenerative diseases, such as Alzheimer's disease
However, these studies were small, and NMN has not been shown to be effective in clinical trials, so further research is needed to determine the effectiveness of NMN supplements.

NMN supplements have not yet undergone large-scale clinical trials to verify their effectiveness. Currently, research on NMN supplements is mainly focused on animal and in vitro experiments. These studies show that NMN can improve the symptoms of metabolic diseases such as diabetes, fatty liver and obesity, and can delay the aging process.
The long-term health effects of NMN supplementation are not well studied. Existing studies mainly focus on animal and in vitro experiments, which show that NMN can improve the symptoms of metabolic diseases such as diabetes, fatty liver and obesity, and can delay the aging process. However, the results of these studies do not represent the long-term effects of NMN on human health.
1.Introduction Nicotinamide adenine dinucleotide phosphate hydrogen (NADPH), also known as reduced coenzyme II, is a critical cofactor in cellular antioxidant systems and lipid synthesis, which links insulin resistance and ferroptosis of pancreatic β cells in the context of metabolic disorders such as diabetes mellitus, playing a central role in maintaining metabolic homeostasis. 2. Biological role of NADPH NADPH functions as a coenzyme essential to cellular metabolism, playing pivotal roles in various critical biological processes, such as ROS scavenging, ROS production, fatty acid synthesis and cholesterol synthesis. 3. Biosynthetic pathway of NADPH Cellular production of NADPH is facilitated through several pathways, including the pentose phosphate pathway, the citric acid cycle, and fatty acid metabolism. The dynamic equilibrium between NADPH synthesis and consumption is essential for preserving cellular redox balance and enabling a host of biosynthetic reactions. 4. The role of NADPH in insulin secretion from pancreatic β-Cells Both redox reaction and metabolic signaling can modulate insulin secretion from pancreatic β-cells, where NADPH plays a central role. It can not only serves as a metabolic coupling factor, but also acts as a custodian of β-cell integrity, delicately managing the interplay between metabolic inputs and insulin output. 5. The interaction between insulin resistance and NADPH A substantial body of evidence reveals that NADPH is critical for the regulation of oxidative stress and inflammatory responses, the main contributors to the pathogenesis of insulin resistance. Specifically, NADPH is implicated in ROS production via NOX and is also utilized in the synthesis of new fatty acids, which contributes to the development of insulin resistance, particularly in the context of obesity-induced chronic inflammation. 6. The impact of NADPH upon the ferroptosis in the context of diabetes In pancreatic β cells, the elevated blood sugar and pro-inflammatory cytokines can trigger oxidative stress and iron accumulation to promote lipid peroxidation, thereby facilitating the ferroptosis. In return, the ferroptosis can reduce insulin secretion and beta cell mass, which is contributive to the progression of diabetes. In general, NADPH plays a dual role in ferroptosis. On the one hand, it can promote ROS generation via NOX. On the other hand, it can support antioxidant defense through glutathione regeneration. In the context of diabetes, NADPH may predominantly fuel processes leading to ferroptosis, mainly due to the enhanced activity and affinity of NOX, which however requires further research for verification. 7. Conclusion NADPH has a critical role in the complex landscape of metabolic disorders, particularly insulin resistance and ferroptosis. Regulating NADPH-related pathways may open up new opportunities for the treatment of metabolic disorders.

1. Introduction The NAD precursor nicotinamide mononucleotide (NMN) shows a beneficial effect on ageing, yet excessive NMN accumulation may lead to axon degeneration. How to make the anti-ageing effect of NMN compatible with axonal degeneration caused by NMN accumulation is still a challenge. A preliminary discussion on this issue is conducted in this study. 2. The definition and pathological changes of axonal degeneration Axonal degeneration refers to degenerative changes in the axon as a result of direct damage to the primary or as a result of diseases such as neuronal metabolic disorders, which is a common pathological change of the nervous system. The pathological changes after axonal injury include axonal swelling, fracture, retraction and atrophy. 3. The relationship between NMN and sterile alpha and TIR motif–containing 1 (SARM1) SARM1 is a multi-functional enzyme with base exchange activity, which can cleave nicotinamide adenine dinucleotide (NAD) into adenosine diphosphate ribose (ADPR), cyclic adenosine diphosphate ribose (cADPR) and nicotinamide (NAM). A substantial body of evidence mirrors that the degenerative enzyme SARM1 will be bound to and be activated by NMN. Hence, failed conversion of sufficient NMN into NAD may give rise to toxic NMN accumulation and axon degeneration. 4. The specific pathway of axon degeneration NMN only induces axon degeneration in the presence of SARM1, placing the toxic accumulation on a common pathway of axon death. Notably, nicotinamide mononucleotideadenylyltransferases (NMNATs) has a broader, compartment-specific regulatory role in SARM1 activity. For instance, NMNAT2 depletion is associated with SARM1 activation in axons. In a nutshell, NMNAT2 depletion can give rise to NMN accumulation. Next, NMN binds to and activates the pro-degenerative protein SARM1, leading to rapid NAD consumption and axon degeneration. 5. The impacts of NAD precursors upon axonal health NAD precursors are likely to be safe for most people, but there is a risk for people with compromised NMNAT activity, as these supplements could cause SARM1 activation and neurodegeneration. In healthy individuals, rapid conversion from NMN into NAD can be accomplished by NMNAT2, which is conductive to the prevention of NMN toxic accumulation and maintenance of healthy neurons and axons. Yet, downregulation of NMNAT2 level or activity may result in the upregulation of NMN, thereby leading to SARM1 activation, increased axonal vulnerability and/or axon degeneration. 6. The factors for SARM1 activity SARM1 activity is regulated by a ratio between NMN and NAD. When NMN rises, partial inhibition of SARM1 is only seen at high concentrations of NAD. Inefficient conversion of NMN into NAD because of compromised NMNAT activity is the most likely scenario in which NMN can become toxic. The change in NMN level close to the physiological concentration has a much more significant impact on SARM1 activity than NAD level. A twofold increase in NAD level is not sufficient to delay axon degeneration after injury, and even higher NAD level only temporarily delays axon degeneration. 7. The interaction between SARM1 activation and ageing effect of NMN Sub-lethal/chronic SARM1 activation could increase axonal vulnerability or have a significant impact upon NAD homeostasis and important intracellular signalling pathways in neurons.It is pivotal for life to preserve NAD homeostasis. Maintaining NAD homeostasis could be a viable anti-ageing strategy. Similarly, NMNAT2 depletion increases axon vulnerability and the level of the NMNAT2 is declined with ageing. These findings signify that SARM1 and NMNAT2 may be the key factor to reconcile the axonal degeneration caused by the accumulation of the NAD precursor NMN and ageing effect of NMN. 8. Conclusion Efficient conversion of NMN into NAD is key to preventing SARM1 activation and neurotoxicity. SARM1 and NMNAT2 may be the intersection factors between axon degeneration and anti-ageing therapy.

Introduction The crucial parts of nicotinamide adenine dinucleotide (NAD+) and its metabolites in aging and neurodegeneration have been widely recognized. To spur progress toward biochemical research and interventions targeting aging and neurodegenerative diseases, it is of great significance to accurately quantify NAD+ and its metabolite levels in the NAD+ salvage pathway. Here, a robust and accurate LC-MS/MS method is applied to quantify NAD+ and its metabolites levels in normal and injured mouse sciatic nerve. Limitations of existing methods for quantifying NAD+ and its metabolites Traditional methods for quantifying NAD+ and its metabolites, such as HPLC-UV, NMR, capillary zone electrophoresis, or colorimetric enzymatic assays, face various challenges in sensitivity, selectivity, and indirect measurement. As for existing LC-MS/MS assays for cellular or tissue NAD+ and its metabolites measurements, there are still many difficulties to overcome, such as extended run times, poor chromatographic retention behavior, and unsatisfactory peak shapes. Moreover, only one to three substances in the NAD+ salvage pathway can be covered by these methods. The modifications of LC-MS/MS method On the basis of existing LC-MS/MS assays, the modifications regarding the chromatographic conditions, surrogate matrix and MS/MS conditions are conducted. Specifically, 5 μM of methylene phosphonic acid is employed as the mobile phase additive, which explicitly promotes the signal intensity and peak shape. Given the relatively clean and simple nature of never samples and their small size, ultrapure water is tested as a substitute matrix. Instead of hydrophilic interaction liquid chromatography column and hypercarb column, the Waters Atlantis Premier BEH C18 AX column is utilized, whose unique MaxPeak HPS high-performance surface technology (passivating the column inner wall, eliminating metal surface) enables the high reproducibility, peak symmetry, and baseline separation of all analytes. Besides, MS conditions are optimized to minimize the NAD+ interference signal in the cyclic adenosine diphosphate ribose (cADPR) channel while maintaining the response of cADPR and nicotinamide mononucleotide (NMN), with 4000V for ion spray voltage, 450℃ for turbo heater temperature, 50 psi for Gas 1, 50 psi for Gas 2, 30 psi for curtain gas, and 12 psi for collision gas. Representative chromatogram of nerve samples (normal vs injured) All five analytes achieve baseline separation, where cADPR is a sensitive biomarker in the neurodegeneration model. Herein, sciatic nerve axotomy induces axonal degeneration, leading to reduced NAD+ level and elevated NMN level in the injured nerves, resulting in about a 2-fold increase in the NMN/NAD+ ratio. Simultaneously, the levels of nicotinamide (NAM) and adenosine diphosphate ribose (ADPR), are decreased by about 2-fold, while cADPR level is increased by more than 8-fold. These results are consistent with those of previously reported research, verifying the accuracy of this modified LS-MS/MS method in quantifying NAD+ and its metabolites. Conclusion This modified LC-MS/MS method enables effective baseline separation of NAD+, NMN, NAM, ADPR, and cADPR within a brief runtime of 5 min, which is contributive to early diagnoses of various neurological disorders and drug development for aging and neurodegenerative diseases.
