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.
NMN supplements may cause side effects such as upset stomach, diarrhea, and nausea. There is also research showing that NMN supplements may affect insulin sensitivity and insulin levels, so people with diabetes should consult their doctor before taking them.
NMN supplements have not yet undergone large-scale clinical trials to verify their effectiveness. Currently, research on NMN supplements is mainly focused on animal and in vitro experiments. These studies show that NMN can improve the symptoms of metabolic diseases such as diabetes, fatty liver and obesity, and can delay the aging process.
The long-term health effects of NMN supplementation are not well studied. Existing studies mainly focus on animal and in vitro experiments, which show that NMN can improve the symptoms of metabolic diseases such as diabetes, fatty liver and obesity, and can delay the aging process. However, the results of these studies do not represent the long-term effects of NMN on human health.
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 senescence in mammals is generally concomitant with the dysregulation of intestinal homeostasis and the accumulation of mitochondrial DNA (mtDNA) mutations. High-burden mtDNA mutations lead to NAD+ depletion and activate the transcription factor ATF5-dependent UPRmt, which in turn promotes and exacerbates the intestinal senescence phenotype. By supplementation with the NAD+ precursor NMN, this intestinal senescence phenotype can be rescued to some extent, as evidenced by the recovery of intestinal organoid differentiation and the increased number of intestinal stem cells. 2. NAD+ depletion during intestinal senescence caused by mtDNA mutations There is impairment of NADH/NAD+ redox in Mut/Mut*** intestines, as manifested by the enriched NADH dehydrogenase complex assembly pathway. Through transfection of intestinal crypt cells with SoNar (a NADH/NAD+ sensor), a higher NADH/NAD+ ratio is observed in Mut/Mut*** mice, hinting the perturbed redox potential. Likewise, following transfection of intestinal crypt cells with FiNad (a NAD+ sensor), less NAD+ content is discovered in the Mut/Mut*** cells. All of these findings mirror NAD+ depletion in the intestinal senescence triggered by mtDNA mutations. Note: mtDNA mutations are classified into four types: negligible (WT/WT), low (WT/WT*), moderate (WT/Mut**) and high (Mut/Mut***). 3. The link between mtDNA mutation content and physiological intestinal senescence The small intestine of aged mouse intestine is characterized by decreased intestinal crypt number, increased villus length, higher expression of CDKN1A/p21 (a well-known senescence marker) and shorter telomere length, which is accompanied by accumulation of mtDNA mutations, primarily low-frequency (less than 0.05) point mutations. 4. LONP1 protein as a candidate marker for intestinal senescence caused by accumulated mtDNA mutations Mitochondrial unfolded protein response (UPRmt) is activated by a variety of mitochondrial stresses, including protein imbalances between mitochondria and the nucleus as well as impaired mitochondrial protein transport. The hallmarks of UPRmt are increased protein expression levels of LONP1, HSP60 and ClpP. Noteworthily, only LONP1 protein is specifically upregulated in senescent UPRmt activation triggered by accumulated mtDNA mutations, which may be a candidate biomarker for intestinal senescence. 5. The role of NAD+ in intestinal senescence induced by elevated mtDNA mutations. NAD+ repletion in vivo alleviates the small intestine senescent phenotypes caused by mtDNA mutation burden, and rescues the decreased colony formation efficiency in Mut/Mut*** intestinal organoids. NAD+-dependent UPRmt triggered by mtDNA mutations regulates intestinal senescence. These data further indicate that NAD+ depletion functions as a key mediator of the intestinal senescence induced by accumulated mtDNA mutations. 6. The role of NAD+ in the signal pathways regulating intestinal senescence caused by increased mtDNA mutations NAD+ repletion rescues the Foxl1 downregulation and Notch1 upregulation in Mut/Mut*** mice, suggesting that mtDNA mutation burden can regulate the function or number of niche cells through NAD+ depletion. In addition, NAD+ depletion caused by increased mtDNA mutation burden induces the decline of LGR5-positive intestinal cells via impairment of the Wnt/β-catenin pathway. 7. Conclusion NAD+ repletion is significant for the regulation of intestinal homeostasis, playing a critical role in rescuing the intestinal senescence phenotype caused by accumulated mtDNA mutations.

Introduction Replenishing nicotinamide mononucleotide (NMN) to raise the availability of nicotinamide adenine dinucleotide (NAD+) has been deemed as effective approach to prevent neurodegeneration in aging and pathological conditions including ALS, a fatal progressive neurodegenerative disorder with no known way to cure. The association of SOD1 and TDP-43 with ALS Cu/Zn-superoxide dismutase (SOD1) is the first identified protein associated with familial ALS. In most ALS cases, Transactive Response DNA Binding Protein 43 (TDP-43) pathology is frequently observed. Both SOD1 and TDP-43 have tight association with motor neuron degeneration in patients with ALS. Mutant SOD1 could affect the solubility/insolubility of TDP-43 through physical interactions. Mutant SOD1G93A and the fragment form of TDP-43 can exert synergistic effect to mediate toxic events in apoptosis. The protective effect of NMN on motor neurons NMN can increase the neurite length and complexity in mouse motor neurons and iPSC-derived human motor neurons overexpressing wild-type TDP-43/mutant hSOD1G93A. Meanwhile, it prevents the neuronal death and increased nitro-tyrosine immunoreactivity induced by trophic factor deprivation. In motor neurons overexpressing mutant hSOD1G93A, the neuroprotection conferred by NMN supplementation is mediated by a mechanism that involves an increase in glutathione content. However, this neuroprotective effect does not involve the alteration of glutathione content in non-transgenic or TDP-43 overexpressing motor neurons. The involvement of TDP-43 pathology in ALS NMN supplementation can confer axonal protection in motor neurons isolated from two dissimilar models of ALS, with and without involvement of TDP-43 pathology. Besides, NMN treatment correct the morphological changes induced by TDP-43 overexpression in motor neurons and boost the nuclear localization of TDP-43 and phosphorylated TDP-43, which favors its nuclear localization and averts the detrimental effects of TDP-43 overexpression on neurite length and complexity. Conclusion Supplementation of NAD+ precursor NMN can modulate neurite complexity and survival in motor neurons, showing great therapeutic potential in the context of ALS pathology.
