Bontac Bio-Engineering (Shenzhen) Co., Ltd. (hereafter referred to as BONTAC) is a high-tech enterprise established in July 2012. BONTAC integrates R&D, production and sales, with enzyme catalysis technology as the core and coenzyme and natural products as main products. There are six major series of products in BONTAC, involving coenzymes, natural products, sugar substitutes, cosmetics, dietary supplements and medical intermediates.
As the leader of the global NMN industry, BONTAC has the first whole-enzyme catalysis technology in China. Our coenzyme products are widely used in health industry, medical & beauty, green agriculture, biomedicine and other fields. BONTAC adheres to independent innovation, with more than 170 invention patents. Different from the traditional chemical synthesis and fermentation industry, BONTAC has advantages of green low-carbon and high-value-added biosynthesis technology. What’s more, BONTAC has established the first coenzyme engineering technology research center at the provincial level in China which also is the sole in Guangdong Province.
In the future, BONTAC will focus on its advantages of green, low-carbon and high-value-added biosynthesis technology, and build ecological relationship with academia as well as upstream/downstream partners, continuously leading the synthetic biological industry and creating a better life for human beings.
BONTAC is a reliable partner that we have been working with for many years. The purity of their coenzyme is very high. Their COA can achieve relatively high test results.
I discovered BONTAC in 2014 because David's article in cell about NAD and NMN related showed that he used BONTAC's NMN for his experimental material. Then we found them in China. After so many years of cooperation, I think it is a very good company.
I think green, healthy and high purity are the advantages of BONTAC's products compared with others. I still work with them to this day.
In 2017, we chose BONTAC's coenzyme, during which our team encountered many technical problems and consulted their technical team, which were able to give us good solutions. Their products are shipped very fast and they work more efficiently.
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.
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.

1. Introduction The gut microbiota has long been regarded as one of the key elements contributing to the regulation of host health. Any changes in the composition or quality of the gut microbiota may have physiological consequences for the host. To determine the effect of sweetener stevia (also known as stevioside) on the gut microbiome of healthy population, the stool samples are collected from healthy participants who consume with or without five drops of the sweetener stevia twice daily. Following analyses of 16S rRNA sequencing method, no large-scale change is found in the gut microbiota post 12 weeks of consumption with stevia, hinting the safety of stevia. 2. Insignificant changes in the alpha or beta diversity following consumption of stevia It is discovered that there is no significant difference in alpha diversity (in terms of observed taxa, evenness and Shannon Index) and beta diversity (with regard to PCoA, PERMANOVA, and Jaccard Index) between groups. Nevertheless, PCoA plots shows strong separation along the x-axis. In addition, the community composition in each group is relatively even over time and equally diverse. 3. No clear difference in relative abundances of taxa At the genus level, relative abundances are similar between the control and stevia groups. No major difference is observed in relative abundances at the class, order and family level. Strikingly, butyricoccus is the only one identified taxon exhibiting significant difference at baseline, but not after 12 weeks of stevia consumption. Moreover, Collinsella and Aldercreutzia are two coprococcus species identified as explicitly different at baseline (one higher and one lower when comparing stevia vs. control), which however are significantly elevated after 12 weeks of consumption with stevia. 4. The safe intake volume of sweetener steviol glycosides In the European Food Safety Authority (EFSA), there is a Panel on Food Additives and Flavourings (FAF), which is responsible for evaluating the safety of food additives and establishing acceptable daily intake levels for safe use. Steviol glycosides, one of the extract from stevia, is evaluated by the FAF as well. In accordance to the latest toxicological test, this sweeter is not genotoxic and carcinogenic, without any adverse effects on the human reproductive system or growing children. The expert group has set the acceptable daily intake (ADI) of steviol glycosides at 4 milligrams per kilogram of body weight per day, which is consistent with the level determined by the Joint Expert Committee on Food Additives (JECFA) administered by the US Food and Agriculture Organization (FAO) and the World Health Organization (WHO). 5. Conclusion Regular, long-term consumption of stevia does not overtly alter the composition of the human gut microbiotia. Stevia can be safe as long as the intake volume is controlled appropriately.

1. Introduction Nicotinamide adenine dinucleotide (NAD) compartmentalized in adipocytes can modulate adipocyte differentiation and gene expression, in addition to controlling glucose metabolism. White adipose tissue (WAT), one major adipose tissue, may be one of the direct target for NAD supplementation. 2. About WAT In contrast to brown adipose tissue (BAT), WAT contains a single lipid droplet and few mitochondria. WAT, once thought to be morphologically and functionally unremarkable, is in fact highly dynamic, with plasticity and heterogeneity, which is widely distributed in the subcutaneous tissues and around the internal organs. WAT plays a key role in a range of biological processes, such as maintenance of energetic homeostasis, processing and handling of glycans and lipids, blood pressure control, and host defence, with tight relationship with metabolic disorders such as diabetes. 3. The tissue-specific roles of NAD NMN is synthesized from NAM and NR by NAMPT and NRK, respectively. The synthesized NAD+ from NMN is used as a SIRT1 substrate, which leads to the recycling of NAD+ via the salvage pathway. In this process, NAD+ can exert different effects depending on the tissue. Remarkably, NAD precursors can control metabolic stress particularly via focusing on adipose tissue. 4. The effects of boosting NAD+ on WAT Supplementation of NMN and NR has been shown to reduce body weight and enhance insulin sensitivity in regular chow-fed aged wild-type mice and diet-induced obese mice, respectively. NAM supplementation diminishes fat accumulation in diet-induced obese mice. Additionally, both NMN and NR supplementation prevent inflammation even with different treatment duration. NAM administration boosts mitochondrial biogenesis and glutathione synthesis in WAT. Similarly, it is evidenced that NMN treatment in high fat diet-induced type 2 diabetes mouse model facilitates the recovery of Glutathione S-transferase Alpha 2 (Gsta2) gene expression in the liver. 5. The adipose-specific effects of nicotinamide phosphoribosyltransferase (NAMPT) NAMPT, one NAD regulator in WAT, is a promising therapeutic target for the treatment of metabolic disorders. NAMPT plays a potential role in maintaining adipose tissue homoeostasis, as evidenced by the explicitly blocked adipocyte differentiation and lipid synthesis in vitro post treatment of NAMPT inhibitor FK866. For some reasons such as differences in sex, age, and/or basal levels of cellular NAD+ availability, there are various inconclusive results regarding the impacts of NAD+ metabolism on adipocytes in the adipocyte-specific NAMPT-deficient mouse model or in vitro cell models. Further investigation on the effects of NAD+ supplementation and the distinct functions of NAMPT in adipocytes is still needed. 6. Conclusion The importance of NAD metabolism in WAT has been highlighted. NAD has tissue-specific roles. Specifically, WAT may be one of the direct target for NAD supplementation. Supplementation with NAD+ precursors can reduce fat accumulation and inflammation in adipose tissue. Reference Kwon SY, Park YJ.
