NAD

I. Product Core Positioning

β-Nicotinamide Adenine Dinucleotide (NAD+, CAS 53-84-9), also known as Coenzyme I (Oxidized Form), is the core redox cofactor and signal molecule hub in living organisms. It is deeply involved in hundreds of core physiological processes such as cellular energy metabolism, DNA damage repair, gene expression regulation, and mitochondrial function maintenance.

Based on our core enzymatic synthesis technology, we have developed high-activity, low-endotoxin NAD+ bulk powder. With precise molecular synthesis technology and strict quality control, we provide compliant and efficient raw material supply solutions for IV infusion therapy, high-end anti-aging health management, cutting-edge biomedical research and other fields. It is the core base material for high-end applications in the biotech industry.

III. Core Biological Functions & Technical Application Value

1. Core Molecular Engine of Cellular Energy Metabolism

As the core hydrogen transporter in the mitochondrial electron transport chain, NAD+ is an essential substrate for energy production pathways such as glycolysis, tricarboxylic acid cycle, and oxidative phosphorylation. It participates in more than 90% of intracellular ATP synthesis. The nicotinamide group in its molecular structure reversibly accepts hydrogen atoms and electrons, transferring energy through mitochondrial Complexes I and II, and significantly improving the efficiency of the cellular mitochondrial respiratory chain.

Technical Application: In IV energy infusion therapy, exogenous supplementation of NAD+ can directly supplement cellular energy metabolism substrates,chronic fatigue, slow metabolism, physical decline and other problems caused by mitochondrial function decline. Combined with raw materials such as Coenzyme Q10 and ATP, it can fully activate the energy metabolism pathway and improve the clinical effect of infusion.

2. Key Regulator of NAD+-Dependent Enzyme System

NAD+ is the sole substrate of core enzymes such as Sirtuins deacetylases, PARP polymerases, and CD38/CD157. By regulating the activity of these enzymes, it achieves precise regulation of cellular senescence, DNA repair, and inflammatory responses:

• Sirtuins Family (SIRT1-7): Regulates telomere maintenance, apoptosis, and lipid metabolism by deacetylating histones and non-histone proteins, delaying cellular senescence;
• PARP Family: Identifies and repairs single/double-strand DNA damage, maintains genome stability, and reduces cellular mutation risk;
• CD38/CD157: Regulates the NAD+ metabolic cycle, affecting immune cell activation and inflammatory factor secretion.

Technical Application: In high-end anti-aging IV therapy, NAD+ can promote collagen synthesis in skin fibroblasts and reduce free radical damage by regulating the above enzyme system, while improving cognitive decline related to neurodegenerative diseases. It is the core raw material for “cellular-level anti-aging”.

3. Signal Link for Nerve and Immune Regulation

In the central nervous system, NAD+ participates in the synthesis and signal transmission of neurotransmitters (such as glutamate and dopamine), regulating neuronal excitability by activating NMDAR receptors and improving neural synaptic plasticity; in the immune system, it maintains immune balance by regulating the activation of T cells, B cells, macrophages and cytokine secretion.

Technical Application: For nerve repair and immune regulation IV courses, NAD+ can be synergistically combined with raw materials such as neuropeptides (Semax, Selank) and Thymosin β4. Through the dual mechanism of “energy supplementation + signal regulation”, it improves nerve repair efficiency and immune cell activity, expanding the clinical application scenarios of the course.

1. Enzymatic Synthesis Technology: Precise Synthesis & Unimpaired Activity

Adopt biological enzymatic directed synthesis technology, using Nicotinamide Mononucleotide (NMN) and ATP as substrates, and catalyze the reaction through NAD+ synthetase (NadE/NadD) expressed by recombinant Escherichia coli to achieve precise molecular synthesis:

• Compared with traditional chemical synthesis, enzymatic synthesis does not require high temperature and pressure, has no organic solvent residue, avoids chiral impurities and chemical by-products, and the retention rate of product biological activity is ≥98%;
• Adopt immobilized enzyme technologyto realize continuous and automated production of enzymatic reaction. The purity fluctuation between batches is ≤0.2%, which is stable and suitable for large-scale mass production and customized demand.

2. Multi-Stage Purification Technology: Ultimate Purity & Compliance Standards

Achieve ultimate purification of NAD+ through a three-stage purification system, completely removing impurities and endotoxins:
