2. Core Product Advantages

1. Native Natural Structure with Pure Biological Activity
Adopting salt-free free original molecular structure, it is completely consistent with human endogenous NAD+ without sodium, lithium, potassium and other modified salt ion residues. Its pure biological activity conforms to human natural metabolic rules, serving as the standard control material for all NAD+ derivatives and precursors with higher accuracy in scientific research data.

2. Direct Active Effect without In-Vivo Conversion
As a mature oxidized active NAD+ prototype, it does not require multi-step enzymatic conversion like NMN and NR precursors. It directly acts on mitochondrial energy metabolism, DNA repair, antioxidant and anti-aging pathways with precise targets and faster efficacy, delivering higher bioavailability than most precursor materials.

3. Ultra-High Purity and Reliable Compliance
Produced by enzymatic synthesis and multi-stage precision purification, it achieves ≥99% high purity with strictly controlled heavy metals, endotoxin and harmful residues. Free of chemical residues and modified additives, it meets high safety standards for cell culture, biomedical experiments, high-end dietary raw materials and mild skin care formulas. Complete COA, MSDS and other compliance documents are available for global export.

4. Full Coverage for Scientific Research and Commercial Use
As a benchmark coenzyme raw material in the industry, it is widely applicable to full-range basic scientific research including mitochondrial metabolism research, enzyme activity detection, cell senescence mechanism and pharmacological and toxicological experiments. It is also extensively used in commercial fields such as high-end anti-aging raw materials, functional nutritional formulas and biological intermediates with wider application scenarios than modified derivatives.
