The preparation methods utilized by manufacturers worldwide of NAD powder are mainly divided into chemical synthesis method and biocatalytic method, among which biocatalytic method includes biological fermentation method and enzyme catalysis method. Enzyme catalysis method has gradually become the mainstream direction because of its advantages of green, environmental protection and pollution-free. And then the purity of NAD powder will reach 99% after the procedure of further purifying. But some NAD manufacturers tend to choose the multiple methods to develop the producing of NAD.
Molecules that can be taken in supplement form to increase NAD levels in the body are referred to by some as “NAD boosters.” Studies conducted over the past six decades suggest that the following are some of the many benefits associated with taking an NAD supplement:
Can Help Restore Mitochondrial Function
Helps Repair Blood Vessels —A 2018 mice study found that supplementation could aid in repair and growth of aged blood vessels. There’s also some evidence it can help manage heart disease risk factors like high blood pressure and high cholesterol.
May Improve Muscle Function — One animal study conducted in 2016 found that degenerative muscles had improved muscle function when supplemented with NAD+ precursors.
Potentially Helps Repair Cells and Damaged DNA — Some studies have found evidence that NAD+ precursor supplementation leads to an increase in DNA damage repair. NAD+ is broken down into two component parts, nicotinamide and ADP-ribose, which combine with proteins to repair cells.
May Help Improve Cognitive Function — Several studies conducted on mice have found that mice treated with NAD+ precursors experienced improvements in cognitive function, learning and memory. Findings have led researchers to believe that NAD supplement may help protect against cognitive decline/Alzheimer’s disease.
May Help Prevent Age-Related Weight Gain — A 2012 study showed that when mice fed a high-fat diet were given an NAD supplement, they gained 60 percent less weight than they did on the same diets without the supplement. One reason this may be true is that nicotinamide adenine dinucleotide helps regulate production of stress- and appetite-related hormones, thanks to its effects on circadian rhythms.
Precursors are molecules used in chemical reactions inside the body to create other compounds. There are a number of precursors of NAD+ that result in higher levels when you consume enough of them.

1.Prevention and treatment of viral-induced inflammatory storms
Scientists have found after extensive research that neo-coronavirus has a mechanism similar to SARS virus to activate inflammatory vesicles NLRP3. and the activation of NLRP3 produces more inflammatory factors, generating excessive inflammation and thus triggering a deadly cytokine storm. This problem can be well addressed by NAD+, which inhibits the activity of NF-κB inflammatory pathway and NLRP3 inflammasome by increasing the activity of sirtuins (SIRT1, SIRT2 and SIRT3), thus preventing cytokine storm caused by excessive inflammation. Therefore, Sinclair and other scientists believe that increasing the concentration of NAD+ may play an important role in the prevention and treatment of neocoronavirus and other viral infections.
2.Restoration of virus-induced metabolic disorders
NAD+ is an essential coenzyme for many cellular energy metabolic pathways, present in every cell of the body, involved in thousands of reactions, and an important player in maintaining cellular viability. In the COVID-19 infection model, NAD+ and NMN supplementation was found to be effective in alleviating cell death and protecting the lung.
First, inspect the factory. After some screening, NAD manufactures 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 NAD powder of high quality with the caterias of SGS. Secondly, the purity is tested. Purity is one of the most important parameters of NAD powder. If high purity NAD cannot be guaranteed, the remaining substances are likely to exceed the relevant standards. As the attached certificates demonstrates that the NAD 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.
In the international market, NAD+ food supplements are in production in the United States, the Australian Food and Drug Administration has approved NAD+ products for sale, and Japanese NAD+ manufactures are devoted to extend the market share in China. Li Ka-shing invested HK$200 million in the US NAD manufacturer, whose NAD+ products are being sold by Watsons in Hong Kong! Then Mclane, a company owned by Warren Buffett also joined the NAD market.
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.
Introduction Ginsenoside Rh2, one protopanaxadiol (PPD)-type rare ginsenoside in Panax ginseng, is uncovered to possibly have broad-spectrum pharmacological activity in diversified tumors. It is utilized as an adjuvant drug for preoperative neoadjuvant chemotherapy, postoperative adjuvant chemotherapy, and rescue treatment of advanced cancer, which has been a research hotspot in recent years. Current states on cancer therapies Cancer has emerged as the second largest cause for death across the world, with approximately 9.6 million cancer-related deaths in 2018, in accordance with the statistical report by World Health Organization (WHO). Radiotherapy, chemotherapy and surgery are the preferred option for cancer, whose efficacy is however limited by the tumor relapse and drug resistance, requiring a patch such as adjuvant drugs to fix the bug. For anticancer treatment, over 60% of the approved and pre-new drug application candidates are natural products or synthetic molecules based upon natural product molecular skeletons. Strikingly, ginsenosides act as a promising therapeutic target by virtue of its pharmacological activities such as immune adjustment, anti-tumor, anti-oxidation, and protection of the heart and cerebral vessels. 20(S) ginsenoside Rh2 vs. 20(R) ginsenoside Rh2 There are two stereoisomeric forms of ginsenoside Rh2, namely 20(S) ginsenoside Rh2 and 20(R) ginsenoside Rh2. Relative to the (20R) ginsenoside Rh2, (20S) ginsenoside Rh2 has higher cytotoxic activity towards cancer cells. In a previously reported study, the half maximal inhibitory concentration values of 20(S) ginsenoside Rh2 and 20(R) ginsenoside Rh2 in A549 cells are 45.7 and 53.6 µM, respectively. The underlying mechanisms of ginsenoside Rh2 against tumor Mechanically, the anti-tumor effects of ginsenoside Rh2 are realized by enhancing the body’s immune activity to regulate microenvironment, inhibiting differentiation, angiogenesis, proliferation, invasion, and metastasis of tumor cells, inducing the apoptosis, cell cycle arrest, autophagy, superoxide and reactive oxygen species, and reversing the drug resistance via regulating a series of important tumor-related signaling pathway. For instance, ginsenoside Rh2 can activate CD4+ and CD8a+ T lymphocytes, promote their invasion, and enhance the killing effect of lymphocytes on B16-F10 melanoma cells in a concentration-dependent manner. Besides, the number of tumor cells in the G0/G1 phase is increased significantly post treatment with ginsenoside Rh2 and 5-FU, by which the expansion and migration of tumor cells are effectively hampered. Additionally, the ginsenoside Rh2 downregulates the levels of drug-resistance-related genes (eg. MRP1, MDR1, LRP and GST), making colorectal cancer cells more sensitive to 5-FU. Conclusion Ginsenoside Rh2 plays multifunctional roles in both tumor treatment and tumor microenvironment immunomodulation, which may become a promising choice of medication for patients with tumors in the future.

1. Introduction Diabetic peripheral neuropathy (DPN) is one of the most frequent complications of diabetes, ans also a major cause of foot ulcers, disability, and eventual amputation. With the prolongation of the diabetes, about 50% of people with diabetes will eventually develop DPN. Notably, supplementing NAD+ precursors could alleviate DPN symptoms by increasing the NAD+ level and activating the sirtuin-1 (SIRT1) protein. 2. The reversal effect of NAD+ precursors on DPN In vitro, the Dorsal Root Ganglion neurons (DRGs) isolated from diabetic mice are exposed to the NAD+ precursor Nicotinamide Riboside (NR) or Nicotinamide Mononucleotide (NMN). It is found that the NAD+ level, the SIRT1 protein, and the deacetylation activity are elevated, followed by the boosted neurite growth, the improved nerve function, and the reversal of IENFD loss. In vivo, supplement of NMN or NR also offsets the neuropathy in C57BL6 mice induced by streptozotocin (STZ) or high fat diet (HFD), as manifested by the improved sensory function, normalized nerve conduction velocities, and restored intraepidermal nerve fibers. 3. The increase of neurite length in a SIRT1-dependent manner post the addition of NMN/NR SIRT1, one of the most unique NAD+ consuming enzymes, can protect against DPN when activated, which may attribute to the improved mitochondrial function and energy homeostasis. Apart from these, SIRT1 activity in the nucleus can deacetylate the transcriptional and co-transcriptional factors that regulate glucose homeostasis and fat oxidation. The activation of SIRT1 is critical for axonal regeneration. NMN/NR treatment or transfection with SIRT1 overexpression vector can directly facilitate the neurite growth in cultured DRG neurons, which however is hindered by the SIRT1 inhibitor EX527, hinting the significance of SIRT1. 4. The association of SARM1 with NMNAT2 in axonal degeneration of DPN Sterile alpha and Toll/interleukin-1 receptor motif-containing 1 (SARM1) controls the axonal degeneration and regeneration via a well-regulated system comprising NAD+ and NMN. NAD and NMNAT2 can boost vesicular glycolysis and axonal transport to maintain the axonal health. The mitochondrial localization of SARM1 complements the coordinated activity of NMNAT2 that promotes axonal survival. 5. Conclusion Supplementing NAD+ precursors may be a promising approach for the treatment of DPN. A SARM1 inhibitor coupled with either NR or NMN may be more effective than a single agent alone in preventing or treating DPN. Reference Chandrasekaran K, Najimi N, Sagi AR, et al.
