NMN powder in general is typically produced via chemical or enzymatic synthesis, or fermentation biosynthesis. There are pros and cons to all three methods.
Chemical synthesis is expensive and labor intensive, and all raw ingredients used are categorized as “unnatural,” i.e., not from biological systems. There are, however, some advantages from the manufacturer’s perspective. The yield is well suited to mass NMN powder production, and all of those unnatural raw ingredients can be carefully controlled. But there are a number of drawbacks as well. Some of the solvents used in the manufacturing process are seriously bad from an environmental standpoint, and impurities and by-products can be challenging to remove from the finished product – that’s seriously bad for the consumer.
Enzymatic production of NMN powder, on the other hand, is considered a “green preparation method.” Like the chemical route, it’s pricey, but it offers a higher yield and impressively high purity. The finished NMN ticks all the boxes – stable, easily absorbed, lightweight, low density, and a low molecular structure.
Fermentation has also been explored as a method of producing NMN, but yield, though high quality, is pretty abysmal, so many supplement companies quite sensibly look to other, more efficacious processes.

NMN was only considered as a source of cellular energy and an intermediate in NAD+ biosynthesis, currently, the attention of the scientific community has been paid on anti-aging activity and a variety of health benefits and pharmacological activities of NMN which are related to the restoring of NAD+. Thus, NMN has therapeutic effects towards a range of diseases, including age-induced type 2 diabetes, obesity, cerebral and cardiac ischemia, heart failure and cardiomyopathies, Alzheimer’s disease and other neurodegenerative disorders, corneal injury, macular degeneration and retinal degeneration, acute kidney injury and alcoholic liver disease.
Aging, as a natural process is identified by downregulation of energy production in mitochondria of various organs such as brain, adipose tissue, skin, liver, skeletal muscle and pancreas due to the depletion of NAD+ . NAD+ levels in the body decrease as a consequence of increasing NAD+ consuming enzymes when aging There are three different biosynthesis pathways to produce NAD+ in mammalian cells including de novo synthesis from tryptophan, salt and Preiss-Handler pathways. Among these three pathways, NMN is an interproduct by is involved in NAD+ biosynthesis through salt and Preiss-Handler pathways. The salvage pathway is the most efficient and the main route for the NAD+ biosynthesis, in which nicotinamide and 5-phosphoribosyl-1-pyrophosphate are converted to NMN with the enzyme of NAMPT followed by conjugation to ATP and conversion to NAD by NMNAT. Furthermore, NAD+ consuming enzymes are responsible for degradation of NAD+ and consequence nt formation of nicotinamide as a by-product.
The safety of NMN powder cannot be assessed since required clinical and toxicological studies have not been completed yet to establish the recommended safe levels for long term administration. Nevertheless, their safety and efficacy are uncertain and unreliable since most of them have not been back by Rigorous scientific preclinical and clinical testing. This issue has been arisen as manufacturers are hesitant to pay for research and clinical trials due to potential lower profit margin, and there is no authorizing agency to regulate NMN products because it is often product sold as functional food than heavily regulated therapeutic drug. Therefore, more strict approval process has been demanded by consumer advocacy groups requesting regulatory agencies to set standard and restrictions for marketing anti-aging health products, considering safety, health and wellbeing of N red besumers. a panacea for the elderly, because boosting NAD levels when not required may yield some detrimental effects. Therefore, the dose and frequency of NMN supplementation should be carefully prescribed depending on the type of age-related deficiency and all other confronting health conditions of the people. Other NAD precursors over have been studied to diverse age-related deficiencies and they are used for particular deficiencies, only after they are proven for effectiveness and safe to use. Therefore, the same principle should be applied to NMN as well
First, inspect the factory. After some screening, NMN companied that directly face consumers pay more attention to brand building. Therefore, for a good brand, quality is the most important thing, and the first thing to control the quality of raw materials is to inspect the factory. Bontac company actually manufacturing NMN powder of high quality with the caterias of SGS. Secondly, the purity is tested. Purity is one of the most important parameters of NMN powder. If high purity NMN cannot be guaranteed, the remaining substances are likely to exceed the relevant standards. As the attached certificates demonstrates that the NMN powder produced by Bontac reach the purity of 99.9%. Finally, a professional test spectrum is needed to prove it. Magnetic Resonance Spectroscopy (NMR) and high-resolution mass spectrometry (HRMS). Usually through the analysis of these two spectra, the structure of the compound ca n be preliminarily determined.
Introduction Wound healing is a sophisticated process responding to tissue damage, which is associated with numbers of interaction of various cell types, cytokines, growth factors, and other molecules. Strikingly, increasing the nicotinamide adenine dinucleotide (NAD) pool by nicotinamide riboside (NR) can accelerate wound healing and macrophage migration, which is partially achieved through PGE2 synthesis and signaling as well as the function of the NAD+-dependent sirtuin, SIRT3. Regulatory effects of NR on the expression of M1 macrophage markers in human MDMs. NR could modulate the expression levels of canonical M1 (inflammatory phenotype) and M2 (reparative phenotype) cell surface markers during macrophage polarization. With a great detail, a significant downregulation in CD64 and a obvious upregulation of CD197/CCR7 are viewed in the polarized M1 cells incubated with NR. Furthermore, NR increases CD197/CCR7-mediated M1 macrophage migration. The significance of chemotaxis mediator PGE2 in NR-regulated macrophage migration NR-mediated upregulation of macrophage migration through CCL19/CCR7 is dependent on the synthesis of PGE2, an inflammatory lipid mediator in the eicosanoid family. Concretely, NR administration increases the PGE2 level in cultured human monocytes, MDMs, and human serum. In addition, NR-mediated increases in CCR7 expression and CCL19-induced migration are attenuated by PGE2 synthesis blockers. NR/SIRT3/migration axis in human M1 MDMs NR facilitates collective cell migration at a SIRT3-dependent manner in human M1 MDMs during wound healing. Simply put, the degree of wound healing is compared on Day 0 and Day 2 in vehicle- or NR-treated human M1 MDMs. It is found that NR increases the relative degree of migration (relative wound healing) and the rate of wound confluence in the presence of CCL19. Besides, the relative degree of wound density (migration) is blunted by SIRT3 knockdown, while being enhanced by SIRT3 overexpression. Application prospect of NR in wound healing Chronic diabetes is often accompanied with poor wound healing. For instance, diabetic foot ulcers, one of the chief cause of amputations, affect 15% of people with diabetes. Given that NR can drive the macrophage migration to boost chronic wound healing, it may have a broad application prospect in treating the wounds including but not limited to diabetic patients. Conclusion In human macrophages, NR induces surface expression of the chemotaxis CD197/CCR7 receptor and levels of its lipid mediator PGE2 via upregulation of cyclooxygenase 2 and functionally increases macrophage migration and wound healing in a SIRT3-dependent manner.

Introduction The gut is a diverse and dynamic microbiotic system. There are about 100 trillion microorganisms in the gut, which is mainly composed of anaerobic, partially anaerobic, and aerobic bacteria. In the process of ageing, the intestinal tract may show an increase in the permeability of the epithelial barrier and impaired tight junction proteins. Notably, supplementing β-Nicotinamide mononucleotide (NMN) to elevate NAD+ level has been proved to prolong life and maintain the colon health in ageing Mice. Research protocol Zmpste24−/− mice are frequently used in the construction of the prematurely ageing model, due to their features of slow weight gain, malnutrition and progressive hair loss, with a short median survival of about 20 weeks. Herein, to fathom out the role of NMN in maintaining the colon health of ageing mice, Zmpste24−/− mice aged 5-7 weeks are orally gavaged with phosphate-buffered saline (PBS), or NMN at 100/300 mg kg−1 every other day until natural death. Likewise, natural ageing C57BL/6 mice aged 10 months old are subjected to the oral gavage of PBS or NMN at 300 mg kg−1, serving as the the control. During experiments, the body weight of mice is recorded, and their frailty index and fecal samples are detected. The life span and frailty indices in Zmpste24-/- mice after NMN treatment NMN extends the healthy and median lifespan of Zmpste24−/−improves the Zmpste24−/− ageing phenotype. Specifically, the median lifespan of the mice is increased from 21.4 weeks to 25.7 weeks post NMN intervention, with more than 20% growth. Also, NMN effectively increases body weight. Meanwhile, mice have better overall health after NMN treatment, as manifested by the slowly increasing trend towards Sinclair’s frailty indices. The role of NMN in the intestinal tract of ageing mice NMN adjusts the activity of genes involved in ageing mice colons. Simply put, in the presence of NMN supplement, the protein level of transcriptional regulator P53 is reduced, while the expression levels of ageing marker Sirt1, NMNAT2 and NMNAT3 are elevated. NMN improves the pathology of intestinal epithelial cells and intestinal permeability, as evidenced by the upregulation of intestinal tight junction protein (Claudin1,) and the number of goblet cells, the elevated release of anti-inflammatory factor (IL-10), and the increasing beneficial intestinal bacteria (Akkermansia muciniphila and Bifidobacterium pseudolongum). Conclusion NMN supplementation exerts a protective effect on colon mucosa by controlling the activity of genes involved in ageing, intestinal stem cell differentiation and improving intestinal flora homeostasis, which may be a viable strategy for maintaining healthy ageing in the gut.

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.
