NAD+ Powder Product Introduction
NAD+ Powder (Nicotinamide adenine dinucleotide) is an essential pyridine nucleotide, which is not only a classic coenzyme in redox reactions but also a Sirtuins, poly ADP-ribose polymerases (PARPs) ), CD38, and other co-substrates of NAD+-dependent enzymes.
nad+ bulk powder can directly or indirectly affect many key cellular functions, including energy metabolism, DNA repair, cellular senescence, epigenetics, and intracellular calcium signaling, which are important for maintaining tissue metabolic homeostasis and healthy aging to important. In a variety of organisms, including humans, aging is accompanied by a gradual decline in cellular and tissue NAD+ levels, and this decline is causally linked to many aging-related diseases, including neurodegeneration, metabolic dysfunction, immune dysregulation, and more.

How is NAD+ Powder synthesized in the body?
● De novo synthesis pathway:
The de novo synthesis pathway utilizes the dietary amino acid tryptophan to generate NAD+, and after tryptophan enters cells through transporters SLC7A5 and SLC36A4, it is converted to indoleamine 2,3-dioxygenase or tryptophan 2,3-dioxygenase The enzyme is initialized to generate the intermediate metabolite kynurenine. Kynurenine represents the main branch point of the pathway. One of the branch metabolic pathways is kynurenine to generates α-amino-β-carboxyl through a series of enzymatic reactions. The acid ε-semialdehyde is then spontaneously cyclized to quinolinic acid, which is converted to nicotinamide mononucleotide by quinolinic acid phosphoribosyltransferase and joins the Preiss-Handler pathway.
● Preiss-Handler way:
The Preiss-Handler pathway utilizes nicotinic acid (NA) to synthesize NAD+, and NA enters cells through the transporter SLC5A8 or SLC22A13 and is converted into nicotinamide mononucleotide by the action of nicotinic acid phosphoribosyltransferase. Nicotinamide mononucleotide adenylyltransferase (NMNAT) is a key enzyme in this pathway. In the presence of ATP, nicotinamide mononucleotide can be converted into nicotinic acid dinucleotide, and then by NAD+ synthase ultimately produces NAD+.
● Remedial Synthetic Routes:
In mammals, pure nad+ powder is mainly synthesized through the NAM salvage synthesis pathway. NAM is obtained through food but is mainly recovered from NAD+ depletion reactions, including NAD+-dependent deacylation reactions and ADP-ribosylation reactions. NAM is an invariant Charged molecule that can diffuse rapidly across the plasma membrane and mitochondrial membrane, and NAM is converted to nicotinamide mononucleotide (NMN) by nicotinamide phosphoribosyltransferase (NAMPT), which can also be converted by nicotinamide acyltransferase (NAMPT). The nicotinamide riboside (NR) is catalyzed by nicotinamide riboside kinase and converted to NAD+ by an NMNAT-dependent ATP reaction in the final step of the salvage pathway.
How is NAD+ Powder consumed in the body?
NAD+ can be cleaved by NAD+ consuming enzymes (including Sirtuins, PARPs, CD38, and CD157, etc.) to generate NAM and ADP-ribose. Sirtuins are NAD+-dependent deacetylases, and seven classes (SIRT1~7) have been identified in mammals, distributed in the nucleus (SIRT1, SIRT6, and SIRT7), cytoplasm (SIRT2) and mitochondria (SIRT3, SIRT4, and SIRT5) However, under certain conditions, Sirtuins may exist in subcellular compartments distinct from their primary locations, such as in cardiomyocytes, where SIRT1 is localized in the nucleus during development but predominantly in the cytoplasm in adults.
Another NAD+ depleting enzyme is PARPs, which cleaves NAD+ and transfers single or multiple ADPRs to target proteins to form mono-, oligo- or poly-ADP-ribose polymers, and release NAM at the same time, a process called mono-ADP-ribose station or poly-ADP-ribosylation.
