When applied to cultured cells, the NMNH is shown to be more efficient than NMN as it was able to “significantly increase NAD+ at a ten times lower concentration (5 µM) than that needed for NMN”. Moreover, NMNH shows to be more effective , as at 500 µM concentration, it achieved “an almost 10-fold increase in the NAD+ concentration, while NMN was only able to double NAD+ content in these cells, even at 1 mM concentration.”.
Interestingly, NMNH also appears to act quicker and has a longer-lasting effect compared to NMN. According to the authors, NMNH induces a “significant increase in NAD+ levels within 15 minutes”, and “NAD+ steadily increased for up to 6 hours and remained stable for 24 hours, while NMN reached its plateau after only 1 hour, most likely because the NMN recycling pathways to NAD+ had already become saturated.”.

NADH is synthesized by the body and thus is not an essential nutrient. It does require the essential nutrient nicotinamide for its synthesis, and its role in energy production is certainly an essential one. In addition to its role in the mitochondrial electron transport chain, NADH is produced in the cytosol. The mitochondrial membrane is impermeable to NADH, and this permeability barrier effectively separates the cytoplasmic from the mitochondrial NADH pools. However, cytoplasmic NADH can be used for biologic energy production. This occurs when the malate-aspartate shuttle introduces reducing equivalents from NADH in the cytosol to the electron transport chain of the mitochondria. This shuttle mainly occurs in the liver and heart.
Nicotinamide adenine dinucleotide (NAD+ ) homeostasis is constantly compromised due to degradation by NAD+ -dependent enzymes. NAD+ replenishment by supplementation with the NAD+ precursors nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR) can alleviate this imbalance. However, NMN and NR are limited by their mild effect on the cellular NAD+ pool and the need of high doses. Here, we report a synthesis method of a reduced form of NMN (NMNH), and identify this molecule as a new NAD+ precursor for the first time. We show that NMNH increases NAD+ levels to a much higher extent and faster than NMN or NR, and that it is metabolized through a different, NRK and NAMPT-independent, pathway. We also demonstrate that NMNH reduces damage and accelerates repair in renal tubular epithelial cells upon hypoxia/reoxygenation injury. Finally, we find that NMNH administration in mice causes a rapid and sustained NAD+ surge in whole blood, which is accompanied by increased NAD+ levels in liver, kidney, muscle, brain, brown adipose tissue, and heart, but not in white adipose tissue. Together, our data highlight NMNH as a new NAD+ precursor with therapeutic potential for acute kidney injury, confirm the existence of a novel pathway for the recycling of reduced NAD+ precursors and establish NMNH as a member of the new family of reduced NAD+ precursors.
First, inspect the factory. After some screening, NMNH companies 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 NMNH 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 NMNH cannot be guaranteed, the remaining substances are likely to exceed the relevant standards. As the attached certificates demonstrates that the NMNH powder produced by Bontac reach the purity of 99%. 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.
Introduction NADH (reduced form of NAD+) serves as a carrier of biological hydrogen and an electron donor, which participates in diverse physiological processes such as protein synthesis, DNA repair, insulin synthesis and secretion, immune response and cell division, playing a critical role in promoting health span and mitigating various disease states. Major enzymatic reactions in substrate metabolism that are dependent upon NAD+/NADH ratio The equilibrium of the NAD+/NADH ratio is vital for maintaining cellular reduction–oxidation (redox) homeostasis and modulating energy metabolism. Several enzymatic reactions in substrate metabolism are carried out in a NAD+/NADH ratio-dependent way. For instance, ketones suppress the increased mitochondrial production of ROS associated with excitotoxic injury by enhancing NADH oxidation (i.e. elevated NAD+/NADH ratio) in the electron transport chain, directly affecting NADH level . NADH in Krebs cycle and glycolysis NADH is produced in glycolysis and the Krebs cycle (also known as citric acid cycle or tricarboxylic acid cycle), which can transfer energy to supply ATP synthesis through the process of oxidative phosphorylation in the inner membrane of the mitochondria. Krebs cycle supplies NADH as an electron carrier to the electron transport chain in mitochondria, while glycolysis-produced NADH can be used by L-lactate dehydrogenase (LDH) or transported to the mitochondria for redox homeostasis. The effects of NADH on the mitochondria are accomplished by specialized shuttle systems (e.g., malate-aspartate or glycerol-3-phosphate). The possible strategies to modulate NADH level The main NAD/NADH biosynthetic pathways include de novo synthesis from tryptophan (TRP), synthesis from either form of vitamin B3, nicotinamide (NAM) or nicotinic acid (NA), or conversion of nicotinamide riboside (NR). Correspondingly, NADH level can be regulated by replenishing NADH precursors (eg. NR and NMN), applying NADH dehydrogenase inhibitors, having diets rich in certain nutrients (eg. vitamin B3), administrating mitochondrial targeting agents and supplementing exogenous NADH. Conclusion NADH may be a versatile therapeutic candidate by leverage of its ability to affect redox homeostasis, mitochondrial functions, and enzymatic reactions.

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.

1. Introduction Nicotinamide adenine dinucleotide (NAD) has been unveiled to be essential for embryonic development. Patients with genetic variants in the NAD+ de novo synthesis pathway often have congenital NAD deficiency disorder (CNDD), a multisystem condition inherited in an autosomal recessive manner. In the context of NAD+ deficiency, all organs and systems, not just vertebrae, heart, kidneys, and limbs, may be affected. 2. The association between NAD synthetase 1 (NADSYN1) and CNDD Individuals delivering biallelic NADSYN1 variants share similar clinical features to those with CNDD. Up till now, almost all of the identified CNDD cases can be attributed to biallelic loss-of-function variants in any of 3 nonredundant genes of the NAD de novo synthesis pathway, including kynureninase (KYNU), 3-hydroxyanthranilate 3,4-dioxygenase (HAAO), or NADSYN1. Among individuals with CNDD identified to date, those with biallelic pathogenic NADSYN1 variants are the most diverse in phenotype. 3. The impact of NADSYN1 variants upon enzymatic activity and phenotype Specifically, NADSYN1 can catalyse the amidation of nicotinic acid adenine dinucleotide (NaAD) to NAD. Biallelic pathogenic variants in NADSYN1 cause a metabolic block in both the de novo pathway and the Preiss-Handler pathway, leading to NAD deficiency. Biallelic NADSYN1 loss-of-function variants impact the NAD metabolome of humans. Post-birth phenotypes involve feeding difficulties, developmental delay, short stature, etc. 4. Mouse embryogenesis disrupted by the loss of NADSYN1 In NADSYN1-/- mouse embryos, NAD-dependent malformations occur when maternal dietary NAD precursors are limited during gestation. The affected Nadsyn1-/- embryos most frequently present malformations of the kidneys, eyes, and lungs. 5. The preventative effect of amidated NAD precursor supplementation against CNDD NADSYN1-dependent embryo loss and malformation in mice are preventable by dietary supplementation of amidated NAD precursors (NMN and NAM) during pregnancy. Maternal diet–derived NAD precursors primarily determine the development of healthy embryos. 6. Conclusion NAD-boosting supplements are essential for individuals with biallelic loss-of-function variants in NADSYN1. Maternal NAD precursor supplementation, to some extent, can reduce the risk of developing CNDD. Reference Szot JO, Cuny H, Martin EM, et al.
