I.Core Product Positioning

**β-Nicotinamide Mononucleotide (NMN, CAS 1094-61-7)** is a key precursor for NAD+ (Coenzyme I) synthesis in organisms, with the molecular formula C₁₁H₁₅N₂O₈P and a relative molecular mass of 334.22. It exists in two isomers, α-NMN and β-NMN, among which β-NMN is the only biologically active form. It can quickly penetrate cell membranes, replenish intracellular NAD+ levels, and regulate hundreds of core physiological processes in the human body.

III. Core Biological Functions and Technical Application Value

1.Efficient NAD+ Supplementation: The “Reversal Switch” for Cellular Aging

As the most direct precursor of NAD+, NMN can directly penetrate cell membranes into cells without multiple metabolic conversions, rapidly increasing intracellular NAD+ levels. The NAD+ content in the human body in middle age is only 50% of that in young age, and supplementing NMN can effectively reverse this decline process, activate cellular energy metabolism and repair mechanisms, and delay cellular aging from the root. It is the core raw material support for “cellular-level anti-aging”, a mechanism that has been confirmed by many international scientific research studies.

Technical Application: In high-end anti-aging IV infusion therapy, NMN can directly supplement cellular NAD+ reserves, and when combined with raw materials such as Glutathione (GSH) and Coenzyme Q10, it can synergistically enhance anti-aging effects. In the field of dietary supplements, it can be made into enteric-coated capsules, oral solutions and other dosage forms to improve bioavailability, adapting to the needs of the general public for anti-aging and staying up late conditioning.

2.Core Engine of Cellular Energy Metabolism

NAD+ is a key coenzyme in the mitochondrial oxidative phosphorylation process, participating in more than 90% of intracellular ATP synthesis. By supplementing NAD+, NMN can significantly improve the efficiency of the mitochondrial respiratory chain, alleviate chronic fatigue, slow metabolism, decreased physical strength and other problems caused by mitochondrial dysfunction. At the same time, it regulates sugar, lipid and amino acid metabolism, maintains the body’s energy balance, and provides sufficient power for cellular activities.

**Technical Application**: It is suitable for health management programs for office workers and middle-aged and elderly groups, which can relieve fatigue and improve energy. In the field of sports nutrition, it can assist in post-exercise recovery and reduce muscle damage. In the field of scientific research, it is used for experimental research related to cellular metabolism and mitochondrial function, with high data reproducibility.

3.Gene Repair and Neuroprotection: Multi-Dimensional Protection of Cellular Health

NAD+ is the only substrate for core enzymes such as Sirtuins deacetylases and PARP polymerases. By increasing NAD+ levels, NMN can activate the Sirtuins family (SIRT1-7), regulate telomere maintenance and cell apoptosis, promote DNA damage repair, and reduce the risk of cellular mutations. At the same time, NMN can improve neural synaptic plasticity, promote neurotransmitter synthesis, protect neurons from damage, alleviate cognitive decline, and has important value for the research of neurodegenerative diseases.

**Technical Application**: In the field of scientific research, it is used for the mechanism research of neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease. In high-end health management, it can be used for conditioning programs related to cognitive function improvement and neuroprotection. In formulation R&D, it can develop special raw material formulas for neural health.

IV.Our Core Technical Advantages (Differentiated Competitiveness)

1.Full Enzymatic Synthesis Process: Pure, Efficient and Industry-Leading

We adopt multi-enzyme synergistic catalysis technology expressed by recombinant Escherichia coli, using nicotinamide (NAM), ribose and ATP as substrates, and directionally synthesize β-NMN through catalysis by immobilized enzymes (RK, PPM, NRK). The whole process is free of heavy metal catalysts and organic solvent residues, completely solving the pain points of low purity, many impurities and high environmental pressure of traditional chemical synthesis methods. It is currently the recognized high-end production technology route in the industry.

Core Advantages: The biological activity retention rate is ≥98%, the β-isomer purity is ≥99.0%, and the purity fluctuation between batches is ≤0.2%; the reaction conditions are mild (around 25℃), the wastewater discharge is reduced by 70% compared with chemical synthesis methods, which is in line with green manufacturing standards; automated and continuous production is realized, with an annual output of more than 50 tons, which can meet the needs of large-scale bulk procurement. At the same time, through technical optimization, the production cost is reduced by 40% compared with traditional enzymatic methods, with significant cost performance advantages.
