Molecules that can be taken in supplement form to increase NAD levels in the body are referred to by some as “NAD boosters.” Studies conducted over the past six decades suggest that the following are some of the many benefits associated with taking an NAD supplement:
Can Help Restore Mitochondrial Function
Helps Repair Blood Vessels —A 2018 mice study found that supplementation could aid in repair and growth of aged blood vessels. There’s also some evidence it can help manage heart disease risk factors like high blood pressure and high cholesterol.
May Improve Muscle Function — One animal study conducted in 2016 found that degenerative muscles had improved muscle function when supplemented with NAD+ precursors.
Potentially Helps Repair Cells and Damaged DNA — Some studies have found evidence that NAD+ precursor supplementation leads to an increase in DNA damage repair. NAD+ is broken down into two component parts, nicotinamide and ADP-ribose, which combine with proteins to repair cells.
May Help Improve Cognitive Function — Several studies conducted on mice have found that mice treated with NAD+ precursors experienced improvements in cognitive function, learning and memory. Findings have led researchers to believe that NAD supplement may help protect against cognitive decline/Alzheimer’s disease.
May Help Prevent Age-Related Weight Gain — A 2012 study showed that when mice fed a high-fat diet were given an NAD supplement, they gained 60 percent less weight than they did on the same diets without the supplement. One reason this may be true is that nicotinamide adenine dinucleotide helps regulate production of stress- and appetite-related hormones, thanks to its effects on circadian rhythms.
Precursors are molecules used in chemical reactions inside the body to create other compounds. There are a number of precursors of NAD+ that result in higher levels when you consume enough of them.

The preparation methods of NAD powder are mainly divided into chemical synthesis method and biocatalytic method, among which biocatalytic method includes biological fermentation method and enzyme catalysis method. Enzyme catalysis method has gradually become the mainstream direction because of its advantages of green, environmental protection and pollution-free. And then the purity of NAD powder will reach 99% after the procedure of further purifying.
Nicotinamide adenine dinucleotide (NAD) has several essential roles in metabolism. It acts as a coenzyme in redox reactions, as a donor of ADP-ribose moieties in ADP-ribosylation reactions, as a precursor of the second messenger molecule cyclic ADP-ribose, as well as acting as a substrate for bacterial DNA ligases and a group of enzymes called sirtuins that use NAD+ to remove acetyl groups from proteins. In addition to these metabolic functions, NAD+ emerges as an adenine nucleotide that can be released from cells spontaneously and by regulated mechanisms, and can therefore have important extracellular roles.
First, inspect the factory. After some screening, NAD 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 NAD powder of high quality with the caterias of SGS. Secondly, the purity is tested. Purity is one of the most important parameters of NAD powder. If high purity NAD cannot be guaranteed, the remaining substances are likely to exceed the relevant standards. As the attached certificates demonstrates that the NAD powder produced by Bontac reach the purity of 99.9%. 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.
The difference all comes down to the charge of these coenzymes. NAD+ is written with a superscript + sign because of the positive charge on one of its nitrogen atoms. It is the oxidized form of NAD. It’s considered “an oxidizing agent” because it accepts electrons from other molecules.
Although they are different chemically, these terms are mostly used interchangeably when discussing their health benefits. Another term you may come across is NADH, which stands for nicotinamide adenine dinucleotide (NAD) + hydrogen (H). This is also used interchangeably with NAD+ for the most part. Both are nicotinamide adenine dinucleotides that function as either hydride donors or hydride acceptors. The difference between these two is that that NADH becomes NAD+ after it donates an electron to another molecule.
With the epidemic control policies loosening worldwide, residents in China, India, Malaysia, Japan and Singapore have suffered a shortage of medicines to varying degrees. But on the other hand, the type of medicines available to the public is dynamically increasing, and at present the anti-Covid-19 stars available on the market include Paxlovid, NMN, etc. What are the similarities and differences between the two in terms of mechanism of preventing and treating the Coronavirus? It is necessary to briefly make out the principle of Covid-19 infection in human cells before discussing the mechanism of action of Paxlovid and NMN. How SARS-CoV-2 infect cells? First, the mature Covid-19 (as shown in Figure 1) is mainly composed of structure proteins including spike (S) protein, nucleocapsid (N) protein, membrane (M) protein and envelope (E) protein and RNA viral gene. Figure 1. SARS-Cov-2 structure The SARS-CoV-2 opens a channel into the cell by its S protein through recognizing and binding to the ACE2 protein receptor of host cells in vivo. After entering the host cell, the SARS-CoV-2 initiates transcription and translation activities, replicating plenty of SARS-CoV-2, disrupting the cell structure and interfering with the normal cell function. Under this mechanism of action, the supplement of medicine directly comes into play on the sides of spike S protein of the Covid-19 and the ACE2 protein of host cells in human body. Paxlovid prevents the synthesis of S proteins of SARS-CoV-2. The mechanism of Paxlovid to treat Covid-19 Paxlovid was made up with two main ingredients, Nirmatrelvir and Ritonavir. Nirmatrelvir combats SARS-CoV-2 by blocking the synthesis of S proteins.The gene information of all SARS-CoV-2 proteins only take over 1/3 of the right side of RNA strand (as shown in Figure 2), and the remaining 2/3 of the RNA gene strand is used for transcription and translation for multiple proteins to synthesize the polyprotein. After the polyprotein is synthesized, it will be cleaved into several functional proteins likely S protein by virus proteases. Figure 2. RNA structure In short, when the SARS-CoV-2 replicates, the RNA initiates transcription and translation for proteins in bulk and then proteases cleave it to form structural proteins (S protein). The main proteases used when replicating is CL3. Nirmatrelvir of Paxlovid binds to the CL3 protease to prevent the cleavage of the SARS-CoV-2 polyprotein so as to interrupt the protein synthesis of viral. (As shown in Figure 3). What’s more, another ingredient, Ritonavir, works by maintaining the concentration of Nirmatrelvir in the body, prolonging and enhancing its efficacy and maintaining the interruption strength for the replicating protease CL3. Figure 3.CL3 in translation The mechanism of NMN to prevent and treat Covid-19 NMN prevents Covid-19 infection by protecting DNA and reducing ACE2 expression, shutting down the pathway of ACE2 protein into human cells. The researchers found that DNA damages accumulates intracellular ACE2 receptor proteins. However, these two enzymes to repair DNA damage, sirtuins and PARP, need to be to motivated by NAD+. Studies showed that NMN supplementation is effective in increasing NAD+ levels and thus reducing ACE2 protein expression. As it demonstrates that experiment proved that a reduction in ACE2 expression after infected with the SARS-CoV-2, along with a reduction in viral load and tissue damage in the lungs (as shown in Figure 4) based on the situation that 200mg/kg of NMN fed to old mice aged 12 months for 7 days. Figure 4. NMN performance in recuding viral loads The study not only reaffirms the convincing for NMN to treat Covid-19 infection, but based on its proven ability to reduce lung pathological damage and even death in mice infected with neointima, NMN may be used in clinical trials to treat patients with Covid-19 infection. It is clear from the above principles of action that both Paxlovid and NMN work on original source of infection to treat and prevent Covid-19. The difference between the two is that Paxlovid interferes with the replication of the virus while NMN closes the door to the entry of Covid-19 into human cells. Both different mechanisms of action are in principle effective in preventing the invasion of Covid-19. References 1.

1. Introduction Disrupted nicotinamide adenine dinucleotide (NAD+) metabolism is increasingly deemed to be one of risk factor for amendable cardiovascular disorders. A substantial evidence has mirrored that restoring NAD+ stock and energy metabolism may be effective in alleviating the symptoms of patients with heart failure (HF), one of the typical cardiovascular disease after myocardial infarction (MI). 2. About HF HF has dominant clinical features of ventricular filling or ejection impairment, concomitant with abnormalities in cardiac structure/function. This disorder afflicts about 38 million patients across the world, and the number of HF patients is on the rise with the age, posing a great threat to the life of patients and bringing huge economic burden on the patient family and society. In terms of drug therapies of HF, the "golden triangle" of beta blockers, ACEI/ARB, and aldosterone receptor antagonists has long been the preferred option. Despite significant improvement on the survival of patients, the 5-year mortality rate remains at 50%. Hence, it is of great significance to seek novel way with high efficacy and safety. NAD supplements may be an effective choice for alleviating HF. 3. Research protocol For further verification of the efficacy of NAD+, MI-induced HF models are constructed in male Sprague-Dawley rats and beagles herein. Subsequently, the left anterior descending arteries of MI-induced HF animals are ligated for 1 week, followed by 4-week treatment with or without low/medium/high dose of NAD+ and the positive control drug LCZ696, an angiotensin receptor blocker-neprilysin inhibitor with an cardioprotective effect after MI. 4. The efficacy of NAD on rats and beagles with MI-induced HF NAD+ shows the equivalent efficacy as LCZ696 in the treatment of MI-induced HF, or even better than LCZ696 at the medium and high doses. In rat/beagle HF models, the heart mass index, heart function, and myocardial fibrosis in the infarct marginal zone are dose-dependently improved post administration of NAD or LCZ696, as manifested by decreased end-systolic volume, end-systolic dimension, creatine kinase and lactic dehydrogenase, as well as the increased ejection fractions, fractional shortening, cardiac output, and stroke volume. In addition, the downregulation of left ventricular blood pressure in the HF model animals is ameliorated post administration of NAD or LCZ696. 5. Conclusion In rat and beagle MI-induced HF models, NAD+ conspicuously alleviates myocardial hypertrophy and cardiac function, represses myocardial fibrosis, and reduces the myocardial infarction, laying a theoretical foundation for the clinical application of energy metabolism therapy with NAD+.

1. Introduction Dengue fever is an acute infectious disease caused by the Dengue virus through the bite of an infected Aedes species (Ae. aegypti or Ae. albopictus) mosquito, with the main symptoms such as high fever, dizziness, headache, rash and severe pains (eye, muscle, joint, or bone pain), etc. This disease is widely prevalent in tropical and subtropical climates. An estimated 100 to 400 million people are infected each year, where over 80% are usually mild and asymptomatic. Nonetheless, severe Dengue fever can increase the risk of death if not treated properly. Thus, early diagnosis of this disease is significant to its timely treatment. Noteworthily, non-structural protein 1 (NS1), a highly conserved glycoprotein, is chiefly secreted during the infection of Dengue virus, which is intensively deemed as the main pathogenesis factor of Dengue fever. Hence, NSI is generally used as a biomarker for the early detection of this disease. In this study, a sandwich enzyme-linked immunosorbent assay (ELISA) in combination with the thio nicotinamide adenine dinucleotide (thio-NAD/S-NAD) cycling method (hereafter termed ultrasensitive ELISA) is utilized to detect NSI, followed by the comparison with NAAT to confirm its detection accuracy. 2. Advantages and disadvantages of traditional detection methods for Dengue fever At present, there are four main detection methods for Dengue fever. Viral isolation and identification have high specificity but are time-consuming, taking at least 5 days. The rapid antigen test is the fastest and most cost-efficient among the other methods, but the sensitivity and specificity are relatively low. Serologic test based on IgM and IgG is limited by the number of days of infection, as the test must be delayed until the level of antibodies rises to a detectable level. In clinic, NAAT is often applied to determine Dengue fever by dirt of its high sensitivity and specificity. However, this method is expensive, laborious, and prone to false positivity, which must be conducted by the trained personnel. To overcome the disadvantages of these methods, a new detection method ultrasensitive ELISA is applied in this study. 3. Workflow of ultrasensitive ELISA with thio-NAD cycling A pair of antibodies is used for capturing the NS1 protein in the sandwich ELISA, and alkaline phosphatase is labeled on the secondary antibody. Aside from the antibodies, an androsterone derivative, 3α-hydroxysteroid dehydrogenase, thio-NAD, and NADH are used to construct the thio-NAD enzyme cycling system. During the thio-NAD cycling reaction, thio-NADH constantly accumulated in a triangular number fashion and could be directly measured at an absorbance of 405 nm. 4. The comparison of ultrasensitive ELISA and NAAT in the detection of Dengue NS1 Protein In NAAT, 60 specimens are dengue-positive, and 25 are dengue-negative. The NAAT cycling threshold (CT) value of those dengue-positive specimens ranged from 12.42 to 31.41. In the ultrasensitive ELISA, 59 specimens are correspondingly positive to the NAAT results, whereas 25 specimens are completely correspondingly negative to the NAAT results. Compared with NAAT, the sensitivity and specificity of the ultrasensitive ELISA are 98.3% and 100%, respectively (Table 2). Of 60 NAAT-confirmed dengue-positive patient specimens, only 1 specimen is negative in the ultrasensitive ELISA. The NAAT data showed that the specimen is a type 4 DENV infection case with a CT value of 21.59. The results of the ultrasensitive ELISA are in almost perfect agreement with the NAAT results, with a kappa value of 0.972 (95% CI: 0.917-1.0). 5. Conclusion Ultrasensitive ELISA method is easy to perform and requires no professional trainees to operate. The detection can be started immediately after receiving a small sample. It is particularly suitable for the early detection of Dengue disease in low-income countries.
