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.”.
The main methods of NMNH powder preparation include extraction, fermentation, fortification, biosynthesis and organic matter synthesis. Compared with other preparations, the whole enzyme becomes the mainstream method owing to the advantages of pollution free, high level of purity and
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 According to the 2020 report of World Health Organization (WHO), there are approximately 2.3 million cases with breast cancer worldwide. Breast cancer has emerged as one of the most malignant tumor in females with significant incidence rate. Although great progress has made in improving the cure rate of early-stage breast cancer in recent years, advanced breast cancer is still hard to be cured. How to reduce the risk of recurrence and metastasis of early-stage breast cancer as well as prolong the survival of patients with advanced breast cancer is still a challenge in the clinical treatment of breast cancer. Notably, ginsenoside Rh2 (GRh2) exerts prominent impacts on retarding the progression of breast cancer via strengthening the immune surveillance of natural killer (NK) cells, a kind of cytotoxic innate lymphocytes critical for tumor immune response. 2. The repressive role of GRh2 in the progression of breast cancer GRh2 hinders the growth, proliferation and metastasis of breast cancer. Simply put, the body weight and tumor volume of model mice are markedly reduced post treatment of GRh2 (10 mg/kg and 20 mg/kg). In addition, the proliferating rate of breast cancer cells is repressed by GRh2 in a dose-dependent manner (5, 10 and 20 mg/kg). Upon the treatment of GRh2 (20 mg/kg), the loss of lung capacity is obviously reduced and the lung metastases formed by MDA-MB-231 tumor cells are strikingly mitigated as well, with no apparent liver metastatic nodules. 3. The enhanced killing effect of NK cells on breast cancer cells following GRh2 treatment GRh2 exerts remarkable effects on retarding the progression of breast cancer via improving the killing ability of NK92MI cells. In a nutshell, the mRNA expression levels of killing mediators perforin and IFN-γ in NK92MI cell-breast cancer cell co-culture system are explicitly upregulated post GRh2 treatment. Strikingly, the reduced lung metastasis of breast cancer by GRh2 is almost counteracted upon the depletion of NK cells. Relative to that of the vehicle control, the amount of CD107a, a degranulation marker of NK cells, is overtly elevated in the presence of GRh2 (20 mg/kg), verifying the enhanced killing activity of NK cells on breast cancer. 4. The underlying molecular mechanism of GRh2 on potentiating the NK cell activity against breast cancer Breast cancer cells reduce the recognition by NKG2D through proteolytic shedding MICA mediated by ERp5 to escape NK cell surveillance. GRh2 interferes with the formation of soluble MICA (sMICA) by suppressing the expression of ERp5 to increase the contents of killing mediators from NK cells, thereby exerting striking effects on fighting against breast cancer. 5. Conclusion GRh2 potentiates the cytotoxic effect of NK cells and enhances the immune surveillance function of NK cells to fight against breast cancer, which may be a potent drug candidate for the prevention and treatment of breast cancer.

1. Introduction On July 2023, the World Health Organization (WHO) has classified the soda sweetener aspartame as a possible carcinogen, but said that aspartame is safe to consume within a daily limit of 40 milligrams per kilogram of a person’s body weight according to the latest assessment results regarding the impacts of the non-sugar sweetener aspartame upon the health. How about another sweetener stevioside? Is stevioside a sugar reducer or a health killer? 2. Current situation on stevioside Stevioside (also termed stevia glycoside) has been regarded as “the third largest source of natural sugar across the world” by virtue of its low calorie, high sweetness, good stability and low price, which is widely used in medicine, daily chemicals, beverage, food, brewing and other industries. 3. Regulatory application and control of stevioside The aforementioned report of WHO on the possible carcinogenesis of soda sweetener aspartame is based on high intake. An adult weighing 70 kilograms or 154 pounds would have to drink more than 9 to 14 cans of aspartame-containing soda daily to exceed the limit and potentially face health risks. There is no need to be worry about the risk of carcinogenesis in the case of healthy intake. The same situation is applicable to another sweetener stevioside. Stevioside is approved to be sweetener in food in countries like Mainland China, Japan, Korea, Australia, New Zealand, the USA and European Union. In China, there are detail specifications on the food additive stevioside (GB 2760-2014). 4. The therapeutic properties of stevioside 4.1 Antitumor effect Stevioside can be applied as a valuable chemotherapy candidate to be further investigated for cancer therapy. The activity of the well-known tumor promoter, 12-O-tetradecanoylphorbol-13-acetate (TPA), is successfully inhibited with stevioside in a murine skin-cancer model. In addition, stevioside can reduce mammary adenoma incidence in F344 rats. 4.2 Anti-hypertensive activity The hypotensive effect observed in rats after chronic oral administration (30 days) of 2.67 g stevia leaves/day has been confirmed in spontaneously hypertensive rats. In that murine model, stevioside (100 mg/kg; i.v.) is able to reduce blood pressure with no change in serum epinephrine, norepinephrine, or dopamine levels. 4.3 Anti-diabetics In diabetic rats, stevioside (0.2 g/kg; i.v. administration) decreases glucose blood levels, yet increases insulin responses and reactions to an intravenous glucose tolerance test (IVGT). Also, stevioside enhances insulin levels above basal during the IVGT, without altering blood glucose response, in normal rats, hinting its potential as a drug candidate for type 2 diabetes. 4.4 Inhibition of pathogenic bacteria Stevioside has demonstrated antibacterial action on various foodborne pathogenic bacteria, including Escherichia coli, a wellknown etiologic agent of severe diarrhea. Regarding antiviral properties, stevioside seems to impede binding of rotavirus to host cells. Rotavirus is commonly associated with pediatric gastroenteritis. 4.5 Anti-inflammatory property In lipopolysaccharide (LPS)-stimulated THP1 cells, stevioside (1mM) inhibits NF-κB. Moreover, stevioside prevents in vitro upregulation of genes involved in liver inflammation. In addition, silico assays demonstrate its antagonistic action in two proinflammatory receptors: tumor necrosis factor receptor (TNFR)-1 and Toll-like receptor (TLR)-4-MD2. 4.6 Antioxidant capability The antioxidant effects of stevioside and rebaudioside A have been confirmed in a fish model, both of which effectively control lipoperoxidation and protein carbonylation. Furthermore, stevioside prevents oxidative DNA damage in the livers and kidneys of a type 2 diabetes murine model. 5 Conclusion As long as the intake is properly controlled, stevioside can be very useful. Stevioside holds a great promise in the clinical treatment and daily health care. Reference Orellana-Paucar A. M. (2023).

Introduction Ginsenoside Rg3 (Rg3) holds great promise as a potential drug for preventing scar formation, but it is often difficult for it to work alone due to its poor water solubility and low bioavailability. Herein, a novel Rg3-loaded dermal extracellular matrix (DECM) hydrogel scaffolds are prepared via 3D printing and nanoloading technologies, which improves the biosafety profile of Rg3 to a large extent, maintains a consistent local drug concentration for an extended duration and prolongs therapeutic effects, realizing the final goal of scar-free healing. The merits of 3D-printed DECM hydrogel scaffolds loaded with Rg3 3D-printed DECM hydrogel scaffolds have good supportability and stability. They could be folded into different shapes without obvious deformation or breakage, closely resembling the properties of natural skin. The continuous porous structure of DECM-2MSN scaffolds enables the faster transport of nutrients, oxygen, water, and metabolic wastes within the platform, which facilitates the wound healing. The uniqueness of 3D-printed DECM hydrogel scaffolds loaded with Rg3 Through decellularization, about 98.57% of dsDNA is removed from DECM, leaving few cellular remnants while preserving collagen in DECM, which simulates the natural extracellular matrix microenvironment for skin defect healing to the greatest extent, reducing the risk of immune rejection. Hydrogel exhibits excellent biocompatibility and solid-like rheological properties. Furthermore, mesoporous silica nanoparticles (MSNs) are introduced into the system to encase the Rg3 to control its release rate and enhance its bioavailability. The role of Rg3-loaded hydrogel scaffolds in wound healing The wound in DECM-2MSNs/Rg3 group has completely healed, exhibiting smooth and uniform regenerated epithelium with clear boundaries between the epidermis and dermis. During the wound healing process, Rg3 can suppress the excessive inflammation, hinder the formation of blood vessels, and prevent excessive and disordered proliferation of granulation tissue at the wound site, as manifested by the low expression of CD31, VEGF and TGF-β levels in DECM-2MSNs/Rg3 group. In the later stages of wound healing, Rg3 could repress collagen accumulation, thereby impeding scarring, without affecting the normal healing of the wound. Conclusion Rg3-loaded hydrogel scaffold can inhibit wound inflammation and collagen accumulation to repress scar formation. By integrating 3D bioprinting and nanoloading technologies to prepare this innovative wound dressing, the efficacy of Rg3 has been greatly improved, providing a novel therapeutic approach for scar-free wound healing.
