2. Core Product Advantages

1. Advanced Disodium Salt Structure with Top-tier Stability
Adopting double sodium ion coordinated stable structure, the molecular framework is more compact and firm, delivering stronger oxidation resistance and anti-degradation performance than free NAD+ and monosodium NAD+. It maintains stable activity during room-temperature storage, aqueous solution preparation and industrial processing without obvious attenuation, eliminating the pain points of easy inactivation and large batch difference of traditional coenzymes, and greatly improving experimental repeatability and product stability.

2. Excellent Water Solubility & High Formula Compatibility
The disodium salt structure greatly optimizes molecular hydrophilicity, achieving faster dissolution speed and higher solution clarity. It is highly adaptable to various water-based formulas, buffer systems and cell culture systems without additional solubilizers, enabling convenient deployment and meeting the requirements of refined formula production and high-end scientific research experiments.

3. Direct Action & Higher Bioavailability
As a mature and directly active oxidized NAD+ substance, it requires no secondary in-vivo conversion. It directly acts on mitochondrial metabolism, DNA repair and antioxidant pathways with faster effect and higher absorption efficiency, showing more stable efficacy than various NAD+ precursor raw materials.

4. Ultra-high Purity & Strict Compliance
Produced by advanced enzymatic synthesis and multi-stage chromatographic purification, the product achieves ≥99% high purity with strictly controlled heavy metals, endotoxin and harmful residues. It meets the high-level standards of biomedical industry, high-end scientific research, cell culture and dietary raw materials. Complete certification documents including COA and MSDS are provided to support global export and compliance verification.
