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.

Unraveling Impacts of Ginsenoside Rg3 Treatment on IL-1β-induced Injury of NPCs

Introduction Intervertebral disc degeneration (IDD) is a frequently seen orthopedic disease, which is accompanied with excessive apoptosis of nucleus pulposus cells (NPCs) and degeneration of extracellular matrix (ECM), with main symptoms of pain and numbness in the waist, legs and feet, as well as inflammation on and around the surface of bone tissues. Strikingly, ginsenoside Rg3, the main active ingredient of ginseng, has been attested to exhibit anti-catabolic and anti-apoptotic effects in IL-1β-treated human NPCs and IDD rats by inactivating the p38 MAPK pathway. The risk factors for IDD IDD is generally associated with risk factors such as aging, excessive exercise, working environment, and genetics. As one ages, the amount of water in the body and in the intervertebral discs will be reduced accordingly. Intervertebral discs that lack moisture will lose their elastic function and become hard. Once there is any stimulation or pressure, the intervertebral disc may crack, leading to intervertebral disc injury. For instance, the mechanical trauma caused by excessive exercise and work may accelerate the fragility of disc and exacerbate IDD. Anti-catabolic and anti-apoptotic effects of ginsenoside Rg3 in IL-1β-treated human NPCs and IDD rats Ginsenoside Rg3 plays an anti-apoptotic role in IL-1β-treated human NPCs and IDD rats, as evidenced by the down-regulation of pro-apoptosis protein Bax and up-regulation of anti-apoptosis protein Bcl-2 in IL-1β-stimulated NPCs and IDD model rats. Besides, ginsenoside Rg3 represses ECM degradation in IL-1β-stimulated NPCs and intervertebral disc tissues of IDD rats, as attested by the decreased expression of ECM degradation-related factors MMPs (MMP2 and MMP3) and ADAMTSs (Adamts4, and Adamts5). Ginsenoside Rg3 exhibits anti-catabolic and anti-apoptotic effects in IL-1β-treated human NPCs. Ginsenoside Rg3 reduces apoptosis and catabolism in IDD rats. Alleviation of ginsenoside Rg3 in IDD via p38 MAPK pathway Ginsenoside Rg3 can alleviate NPC degeneration, recover the arrangement of annulus fibrous, and preserve more proteoglycan matrix via inactivating p38 MAPK pathway. In vitro, the fluorescence intensity of p38 is enhanced in IL-1β-stimulated NPCs, yet ginsenoside Rg3 offsets this promoting effect. In vivo, the phosphorylated p38 level is elevated in NPCs and the intervertebral disc tissues of IDD rats, while ginsenoside Rg3 works inversely. Ginsenoside Rg3 suppresses the IL-1β-stimulated p38 MAPK pathway in human NPCs Ginsenoside Rg3 inactivates the p38 MAPK pathway in IDD rats. Conclusion The anti-catabolic and anti-apoptotic effects of ginsenoside Rg3 in IL-1β treated human disc nucleus pulposus cells and in a rat model of disc degeneration are accomplished by inactivating the MAPK pathway, providing new clues on the treatment of IDD.

Targeting NAD+ Salvage Pathway as a Potential Approach to Combat Obesity

Introduction Mar 4th is determined as the World Obesity Day. World Obesity Federation, UNICEF and WHO have hosted a global youth-led webinar to talk about obesity & youth. The obesity crisis has gradually attracted much attention. The latest report by the Lancet suggests that one billion people are bothered by obesity (2022), with 650 million adults, 340 million adolescents and 39 million children. Recently, etiological studies and interventions for obesity have been progressively focused on the central nervous system, with an attempt to curb the onset of obesity at its source. Notably, targeting NAD+ salvage pathway in hypothalamic astrocytes may be a potential approach to combat obesity. The association of hypothalamic astrocytes and obesity The hypothalamus functions as the appetite regulation center, which receives and integrates the neuroendocrine factors produced by the central nervous system and peripheral tissues to promote or suppress appetite, so as to affect body weight. Noteworthily, aypothalamic astrocytes can apparently decrease glucose clearance and increase plasma insulin levels, playing an essential role in modulating energy metabolism, which are expected to be a new target for obesity treatment. Alleviation of high-fat diet (HFD)-induced obesity by repressing astrocyte NAD+ salvage pathway Under conditions of excessive fat intake, the NAD+ salvage pathway is specifically activated in hypothalamic astrocytes, which restrains the energy expenditure (EE) and fat oxidation in adipose tissues by downregulating sympathetic nerve innervation, eventually resulting in the accumulation of adipose tissue fat and the development of obesity. CD38 as a downstream mediator of astrocyte inflammation induced by the NAD+ salvage pathway. CD38 functions downstream of the NAD+ salvage pathway in hypothalamic astrocytes burdened with excess fat. CD38 knockdown in arcuate nucleus astrocytes diminishes the weight gain, reduces fat mass, increases EE, and lowers RER during HFD consumption. Cd38 depletion in hypothalamic astrocytes may improve hypothalamic inflammation by increasing NAD+ level. Hypothalamic inflammation can not only lead to energy imbalances, but also exacerbate central insulin resistance and leptin resistance, which can lead to the accumulation of fat in peripheral tissues. The role of nicotinamide phosphoribosyltransferase (NAMPT)–NAD+–CD38 axis in obesity In mammals, the salvage pathway represents the primary means of maintaining cellular NAD+ level. A crucial step in the NAD+ salvage pathway is catalyzed by NAMPT. In response to fat overload, the activation of the astrocytic NAMPT-NAD+-CD38 axis induces pro-inflammatory responses in the hypothalamus, eliciting aberrantly activated basal Ca2+ signals and compromised Ca2+ responses to metabolic hormones such as insulin, leptin, and glucagon-like peptide 1, ultimately resulting in dysfunctional hypothalamic astrocytes and contribute to the development of obesity. Conclusion Mechanically, inhibition of hypothalamic astrocytic NAD+ salvage pathway, along with its downstream CD38, mitigates hypothalamic inflammation and attenuates the development of HFD-induced obesity in male mice.

The Molecular Mechanisms Underlying the Interaction Between NAD+/NMN and DBC1

Introduction Oxidized form of nicotinamide adenine dinucleotide (NAD+) and its precursor nicotinamide mononucleotide (NMN) have been uncovered to restore DNA repair and prevent cancer progression via the deleted in breast cancer 1 (DBC1). This research is committed to deciphering the detailed molecular mechanisms. About DBC1 DBC1 is a nuclear protein initially cloned from a human chromosome 8p21 region, which can modulate diversified targets by protein-protein interaction, contributing to various cellular processes such as apoptosis, DNA repair, senescence, transcription, metabolism, circadian cycle, epigenetic regulation, cell proliferation, and tumorigenesis. The affinity and molecular binding mechanisms between NAD+/NMN and DBC1354–396 Under the help of nuclear magnetic resonance (NMR) and Isothermal titration calorimetry (ITC) experiments, it is verified that both NAD+ and NMN have a binding relationship with the NHD domain of DBC1. Specifically, NAD+ interacts with DBC1354-396 through hydrogen bonds, with a binding affinity (8.99 μM) nearly twice that of NMN (17.0 μM) and the key binding sites are primarily residues E363 and D372. The vital roles of E363 and D372 mutagenesis in ligand-protein interaction The N-terminal loop of DBC1354-396 encloses the small ligand within a local space, anchoring NAD+ and NMN to the protein through key amino acid residues E363 and D372 via hydrogen bonding. Conclusion Both NAD+ and its precursor NMN can bind to DBC1's NHD domain (DBC1354–396) at key sites E363 and D372, providing novel clues for the development of targeted therapies and drug research on DBC1-associated disease including tumors.
