NMN powder manufacturing method

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.

Frequently Asked Question

Do you have any question?

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.

The latest research proves: Coenzyme NAD+ can enhance tumor immunity! Expert Comment from Chinese Academy of Sciences

On August 10, 2021, researchers from Shanghai University of Science and Technology published an article titled NAD+ supplement potentiates tumor killing function by rescuing defective TUBBY-mediated NAMPT transcription in tumor infiltrated T cells in Cell Reports, revealing that NAD+ in supplemented during CAR-T therapy and immune checkpoint inhibitor therapy, it can improve the anti-tumor activity of T. At present, the supplementary precursor of NAD+, as a nutritional product,has been verified for human consumption safety.This achievement provides a simply and feasible new method for improving the anti-tumor activity of T cells. Cancer immunotherapies including the adoptive transfer of naturally occurring tumor-infiltrating lymphocytes (TILs) and genetically engineered T cells, as well as the use of immune checkpoint blockade (ICB) to boost the function of T cells, have emerged as promising approaches to achieve durable clinical responses of otherwise treatment-refractory cancers (Lee et al., 2015; Rosenberg and Restifo, 2015; Sharma and Allison, 2015). Although immunotherapies have been successfully used in the clinic, the number of patients benefiting from them is still limited (Fradet et al., 2019; Newick et al., 2017). Tumor microenvironment (TME)-related immunosuppression has emerged as the major reason for low and/or no response to both immunotherapies (Ninomiya et al., 2015; Schoenfeld and Hellmann, 2020). Therefore, efforts to investigate and overcome TME-related limitations in immune therapies are of great urgency. The fact that immune cells and cancer cells share many fundamental metabolic pathways implies an irreconcilable competition for nutrients in TME (Andrejeva and Rathmell, 2017; Chang et al., 2015). During uncontrolled proliferation, cancer cells hijack alternative pathways for more rapid metabolite generation (Vander Heiden et al., 2009). As a consequence, nutrient depletion, hypoxia, acidity, and generation of metabolites that can be toxic in the TME may hinder successful immunotherapy (Weinberg et al., 2010). Indeed, TILs often experience mitochondrial stress within growing tumors and become exhausted (Scharping et al., 2016). Interestingly, multiple studies also indicate that metabolic changes in TME could re-shape T cell differentiation and functional activity (Bailis et al., 2019; Chang et al., 2013; Peng et al., 2016). All these evidences inspired us to hypothesize that metabolic reprogramming in T cells might rescue them from a stressed metabolic environment, thereby reinvigorating their anti-tumor activity (Buck et al., 2016; Zhang et al., 2017). In this current study, by integrating both genetic and chemical screens, we identified that NAMPT, a key gene involved in NAD+ biosynthesis, was essential for T cell activation. NAMPT inhibition led to robust NAD+ decline in T cells, thereby disrupting glycolysis regulation and mitochondrial function, blocking ATP synthesis, and dampening the T cell receptor (TCR) downstream signaling cascade. Building on the observation that TILs have relatively lower NAD+ and NAMPT expression levels than T cells from peripheral blood mononuclear cells (PBMCs) in ovarian cancer patients, we performed genetic screening in T cells and identified that Tubby (TUB) is a transcription factor for NAMPT. Finally, we applied this basic knowledge in the (pre) clinic and showed very strong evidence that supplementation with NAD+ dramatically improves the anti-tumor killing activity both in adoptively transferred CAR-T cells therapy and immune check point blockade therapy, indicating their promising potential for targeting NAD+ metabolism to better treat cancers. 1.NAD+ regulates the activation of T cells by affecting energy metabolism After antigen stimulation, T cells undergo metabolic reprogramming, from mitochondrial oxidation to glycolysis as the main source of ATP. While maintaining sufficient mitochondrial functions to support cell proliferation and effector functions.Given that NAD+ is the main coenzyme for redox, the researchers verified the effect of NAD+ on the level of metabolism in T cells through experiments such as metabolic mass spectrometry and isotope labeling. The results of in vitro experiments show that NAD+ deficiency will significantly reduce the level of glycolysis, TCA cycle and electron transport chain metabolism in T cells. Through the experiment of replenishing ATP, the researchers found that the lack of NAD+ mainly inhibits the production of ATP in T cells, thereby reducing the level of T cell activation. 2.The NAD+ salvage synthesis pathway regulated by NAMPT is essential for T cell activation The metabolic reprogramming process regulates the activation and differentiation of immune cells. Targeting T cell metabolism provides an opportunity to modulate the immune response in a cellular way. Immune cells in the tumor microenvironment, their own metabolic level will also be correspondingly affected. The researchers in this article have discovered the important role of NAMPT in the activation of T cells through genome-wide sgRNA screening and metabolism-related small molecule inhibitor screening experiments. Nicotinamide adenine dinucleotide (NAD+) is a coenzyme for redox reactions and can be synthesized through the salvage pathway, de novo synthesis pathway, and Preiss-Handler pathway. The NAMPT metabolic enzyme is mainly involved in the NAD+ salvage synthesis pathway. Analysis of clinical tumor samples found that in tumor-infiltrating T cells, their NAD+ levels and NAMPT levels were lower than other T cells. Researchers speculate that NAD+ levels may be one of the factors that affect the anti-tumor activity of tumor-infiltrating T cells. 3.Supplement NAD+ to enhance the anti-tumor activity of T cells Immunotherapy has been exploratory research in cancer treatment, but the main problem is the best treatment strategy and the effectiveness of immunotherapy in the overall population. Researchers want to study whether enhancing the activation ability of T cells by supplementing NAD+ levels can enhance the effect of T cell-based immunotherapy. At the same time, in the anti-CD19 CAR-T therapy model and anti-PD-1 immune checkpoint inhibitor therapy model, it was verified that supplementation of NAD+ significantly enhanced the tumor-killing effect of T cells. The researchers found that in the anti-CD19 CAR-T treatment model, almost all mice in the CAR-T treatment group supplemented with NAD+ achieved tumor clearance, while the CAR-T treatment group without NAD+ supplemented only about 20 % Of mice achieved tumor clearance. Consistent with this, in the anti-PD-1 immune checkpoint inhibitor treatment model, B16F10 tumors are relatively tolerant to anti-PD-1 treatment, and the inhibitory effect is not significant. However, the growth of B16F10 tumors in the anti-PD-1 and NAD+ treatment group could be significantly inhibited. Based on this, NAD+ supplementation can enhance the anti-tumor effect of T cell-based immunotherapy. 4.How to supplement NAD+ The NAD+ molecule is large and cannot be directly absorbed and utilized by the human body. The NAD+ directly ingested orally is mainly hydrolyzed by brush border cells in the small intestine. In terms of thinking, there is indeed another way to supplement NAD+, which is to find a way to supplement a certain substance so that it can synthesize NAD+ autonomously in the human body. There are three ways to synthesize NAD+ in the human body: Preiss-Handler pathway, de novo synthesis pathway and salvage synthesis pathway. Although the three ways can synthesize NAD+, there is also a primary and secondary distinction. Among them, the NAD+ produced by the first two synthetic pathways only accounts for about 15% of the total human NAD+, and the remaining 85% is achieved through the way of remedial synthesis. In other words, the salvage synthesis pathway is the key to the human body to supplement NAD+. Among the precursors of NAD+, nicotinamide (NAM), NMN and nicotinamide ribose (NR) all synthesize NAD+ through a salvage synthesis pathway, so these three substances have become the body's choice for supplementing NAD+. Although NR itself has no side effects, in the process of NAD+ synthesis, most of it is not directly converted into NMN, but needs to be digested into NAM first, and then participate in the synthesis of NMN, which still cannot escape the limitation of rate-limiting enzymes. Therefore, the ability to supplement NAD+ through oral administration of NR is also limited . As a precursor for supplementing NAD+, NMN not only bypasses the restriction of rate-limiting enzymes, but is also absorbed very quickly in the body and can be directly converted into NAD+. Therefore, it can be used as a direct, rapid and effective method to supplement NAD+. Expert Reviews: Xu Chenqi (Excellence and Innovation Center of Molecular Cell Science, Chinese Academy of Sciences, Immunology Research Expert) Cancer treatment is a problem in the world. The development of immunotherapy has made up for the limitations of traditional cancer treatment and expanded the treatment methods of doctors. Cancer immunotherapy can be divided into immune checkpoint blocking therapy, engineered T cell therapy, tumor vaccine, etc. These treatment methods have played a certain role in the clinical treatment of cancer. At the same time, this also makes the current focus of immunotherapy research on how to further enhance the effect of immunotherapy and expand the beneficiaries of immunotherapy.

The Prospect of the NAD+ Precursors in Age-related Diseases

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.

Further Discussion on the Potential Mechanism of NMN Affecting Neuromuscular Junction

1. Introduction In mammalian cells, the majority of NAD+ is produced from metabolites entering the NAD+ salvage pathway. Nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme of the salvage pathway, which can convert nicotinamide (NAM) into nicotinamide mononucleotide (NMN). Neuronal NAMPT is important for pre-/post-synaptic NMJ function, and maintaining skeletal muscular function and structure. 2. The involvement of NAMPT in NAD+ salvage pathway NAMPT activity has a pivotal role in energy metabolism and homeostasis. NAMPT can condense nicotinamide (NAM) and 5-phosphoribosyl pyrophosphate (PRPP) into nicotinamide mononucleotide (NMN). NMN is subsequently synthesized into NAD+ by nicotinamide mononucleotide adenylyltransferase (NMNAT), the enzyme immediately after NAMPT. 3. The effect of NMN on partially reversing the NMJ impairments in NAMPT-/- cKO mice In the presence of NMN treatment, vesicle endocytosis/exocytosis is improved and endplate morphology is restored in Thy1-NAMPT-/-conditional knockout (cKO) mice. Also, loss of NAMPT in projection neurons impairs the endocytosis and exocytosis of synaptic vesicles at NMJs, but NMN can largely prevent these impairments. Furthermore, NMN treatment restores sarcomere alignment rather than mitochondrial morphology. 4. The underlying mechanism of NMN affecting NMJs The ameliorating effects of NMN on NMJs may be realized via NAMPT-mediated NAD+ salvage pathway, and this speculation is confirmed by the ameliorated synaptic vesicle cycling, endplate morphology, and muscle fiber structure and function post 2-week administration of the NAD+ precursor, NMN. 5. Conclusion Mechanically, the effects of NMN improving NMJ function, endplate morphology and muscular structure and contractility possibly involves NAMPT-mediated NAD+ salvage pathway. NMN holds a great promise as a therapeutic agent for skeletal muscle diseases.
