According to recent industrial report, only several products from worldwide NMN manufacturers came close to meeting label claim and contain not enough NMN. Almost products performed better, having at least 88% of the label claim up to small overages. A lone 250 mg product was identified as BRL. In sum, ChromaDex said that 64% of the products tested contained less than 1% of the stated amount of the active ingredient. which should give consumers pause. While this is a limited snapshot of the vast NMN finished product landscape. it does provide a glimpse into the high variability of product quality that is available. The majority of the products may purchase online contain such a small amount of NMN that there would be no clinical benefits achieved from the dose. Another concern with these adulterated products is that the actual contents are not known and could pose a risk to the user the company said in a statement.
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.
1.Raw material production process
Bioenzyme catalysis is a popular production method in the industry. It has a high threshold and several key catalytic enzymes are expensive, accounting for about 80% of the overall production process cost, but it is also the safest and most efficient production method. In the production of NMN by bioenzyme catalysis, the use of food-grade raw materials is an important part of the process to ensure product safety and to ensure that standards are followed.
2.High standard of production conditions
Production conditions refer to the standard of labor consumption required to complete the qualified products of the unit under certain production organization and production technology conditions. There are certifications issued by regulatory authorities, such as cGMP in the United States, TGA in Australia, GMP in Japan, etc.
3.High standard of product testing.
Product testing requires reliable test methods and reagents that are used throughout the production process. They are not only inspection standards for the final product, but also for the intermediate stages of control, including testing of active ingredients, testing of heavy metals such as lead, arsenic and mercury, and testing of pathogenic bacteria, microorganisms and processing by-products.
For NMN products, the commonly used method for active ingredient content testing is high performance liquid chromatography (HPLC), which is efficient, accurate and precise. For different manufacturers, the standards for testing reagents are different. Strict manufacturers will purchase high purity, analytically pure reagents from third party standards companies as controls.
4.Safety assessment
For relatively new raw materials such as NMN, it is not enough for consumers to judge the safety of the product on the side of the merchant alone. At this point, the third-party authoritative assessment report is particularly important.
Currently, there are two generic safety assessment reports, one is a toxicological assessment report and the other is a safety assessment report. In China, toxicological assessment reports usually account for the majority. However, there are still few NMN companies that can issue such reports
5.Storage and Packaging
NMNs are usually stored in sealed containers for up to 12 months. If it can be stored for 24 months with insignificant changes in purity, the stability of NMN is very reliable. Currently, the more common packaging materials are pet or hope, which are pharmaceutical packaging materials. They are non-toxic, odorless, lightweight, portable and effectively isolate air and moisture.
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 backed up 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 sold as functional food product rather 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 consumers. NMN should not be considered as 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 have been studied to discover the efficacy for 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. Common methods for determining the structure of an organic compound include Nuclear Magnetic Resonance Spectroscopy (NMR) and high-resolution mass spectrometry (HRMS). Usually through the analysis of these two spectra, the structure of the compound can be preliminarily determined.
1. Introduction Age-related NAD+ depletion affects physiological functions and contributes to various aging-related diseases. NAD+ precursors can significantly elevate NAD+ level in murine tissues, effectively mitigate metabolic syndrome, enhance cardiovascular health, protect against neurodegeneration, and boost muscular strength, with broad prospect in the anti-aging-related field. 2. The synthesis and metabolism of NAD+ in age-related pathologies NAD+ is synthesized from NAD+ precursors and amino acids tryptophan via three main pathways: De novo, Preiss-Handler, and Salvage. Supplementation of NAD+ precursors can be advantageous in maintaining normal cellular metabolism regulated by NAD+ and NAD+-dependent enzymes such as Sirtuins, PARP, CD38, and SARM1. NAD+ intermediates require conversion into NA to elevate NAD+ level. NAD+ and its metabolism-related enzymes have very important roles in biological processes such as cellular metabolic processes, gene expression, apoptosis and carcinogenesis. NAD+ repletion is drawing attention as an anti-aging intervention. NAD+ precursors, such as NA, NAM, NR, and NMN, provide beneficial effects in various preclinical disease models of age-induced deficits, including metabolic disorders, cardiovascular, neurodegenerative diseases, and musculoskeletal diseases. 3. Comparison on the efficacy of replenishing NAD precursors in pre-clinical studies and clinical studies in age-related pathologies The downregulation of NAD+ level in cells and tissues is not a universal phenomenon for aging-related pathologies. NAD+ merely decreases with age in certain tissues. The efficacy of NAD+ precursors in clinical studies has been limited in comparison with that in the pre-clinical studies. Noteworthily, this issue can be addressed as long as much attention has been paid to the metabolism of NAD. With regards to the oral supplementation of NAD+ precursors, there is obvious link between NAD metabolism and gut microbes. Specifically, oral consumption of NMN is converted into NAMN through interaction with the gut microbiome. In addition, dietary NAM and NR are converted into NA through gut microbiota. 4. Future research directions regarding the NAD+ metabolism It is fundamental to consider how the gut microbiome affects NAD+ metabolism, and changes in microbiome composition may affect the availability of NAD+ precursors. Future studies also require the comparative analysis of different precursors, and the role of gut microbiomes regarding various intermediaries needs to be investigated. Assessment of how NAD+ precursors affect microbiota and how their interaction with NAD+ metabolism benefits the physiological condition is essential for future preclinical and clinical studies. 5. Conclusion Supplementation of suitable NAD+ precursors or intervening in NAD+ metabolism can restore the body's NAD+ level, which is of great practical significance for effectively improving aging-related diseases and prolonging healthy life span is of great practical significance for effectively improving aging-related diseases and prolonging healthy life span. NAD metabolism involves gut microbiome, and in-depth research on their interaction is possibly an important breakthrough in the future to combat aging-related pathologies.

1. Introduction Ginseng has always been highly perceived as a valuable traditional Chinese medicine in China. Currently, much attention also has been paid to ginsenosides, the main active ingredients extracted from ginseng. Strikingly, ginsenoside Rh2, one of the most representative bioactive ginsenosides in Panax ginseng, has immunomodulatory, anti-inflammatory, and anti-tumor activities, showing a therapeutic role in numerous diseases. 2. The therapeutic effect of ginsenoside Rh2 * Enhance the immune function of the human body Ginsenoside Rh2 has the effect of enhancing the immune function of the patient's body. Notewothily, it can effectively reduce the toxicity left by chemotherapy in the human body by improving immunity. *Ameliorate neuropathic pain Intrathecal administration of ginsenoside Rh2 significantly attenuates SNI-induced mechanical allodynia and thermal hyperalgesia. The antinociceptive effect of Rh2 continued until 10 days after SNI surgeryn, showing a potential application value in pain therapy. Figure 1 Intrathecal injection of Rh2 inhibits neuropathic pain in mice * Suppress the inflammation Previous studies have revealed that ginsenoside Rh2 can inhibit spared nerve injury (SNI)-induced increase of proinflammatory cytokines (tumor necrosis factor-α, interleukin-1 and interleukin-6), and significantly inhibit lipopolysaccharide (LPS)-induced activation of BV2 cells. Figure 2 Intrathecal injection of Rh2 reduced expression of proinflammatory cytokines IL-1, IL-6 and TNF-α in SNI mice * Promote the synthesis of albumin Ginsenoside Rh2 acts as an immune regulator to promote the synthesis of albumin, which can provide heat for the human body, protect and stabilize the immunoglobulin in the blood. * Inhibit the growth of tumor cells Ginsenoside Rh2 exhibits a chemical structure similar to that of dexamethasone. In in vitro studies, it can suppress the growth and viability of various cancer cells, induce tumor cell cycle arrest and cellular apoptosis, trigger necrosis and autophagy in cancer cells, inhibit metastasis, and suppress angiogenesis. * Reversal of abnormal tumor differentiation Ginsenoside Rh2 has a differentiation-inducing effect on tumor cancer cells, and can effectively enhance the melanin production ability in cancer cells, thereby causing cancer cells to transform into normal cells in morphology. Table 1 Anticancer effects and mechanisms of ginsenoside‑Rh2 in in vivo studies 3. The difference between ginsenoside Rg3 and ginsenoside Rh2 Figure 3 Molecular struction of ginsenoside Rg3 and ginsenoside Rh2 Both ginsenoside Rg3 and ginsenoside Rh2 have been attested to achieve antitumor effects by strengthening the immune function of the body. Despite their similar mechanisms of action, differences still exist between ginsenoside Rg3 and ginsenoside Rh2. In terms of the molecular structure, ginsenoside Rh2 has only one glycosyl group, whereas ginsenoside Rg3 has two. In addition, ginsenoside Rh2 has a higher bioavailability than ginsenoside Rg3. Ginsenoside Rg3 is easy to be excreted from the body after being taken, and won't make much difference to the body. With regard to the intestinal absorption, ginsenotone Rh2 is about 5 times of ginsenotone Rg3. 4. Conclusion The monosaccharide ginsenoside Rh2 can effectively improve human immunity, enhance disease resistance, and reduce the risk of cancer. Relative to ginsenoside Rg3, ginsenoside Rh2 shows higher cost-efficiency in the intestinal absorption, application scope and efficacy, providing an upgraded health support.

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.
