1. Product Overview
Nicotinamide Riboside (NR) is a key active derivative of Vitamin B3 and a critical precursor of NAD⁺. It participates in hundreds of enzymatic reactions in organisms, serving as a core regulator of cellular energy metabolism, DNA repair, and gene expression.
Maintain Biotech produces NR through independently developed enzymatic synthesis technology. Our products feature high purity, low impurities, eco-friendliness, and high bioavailability. They are widely used in dietary supplements, pharmaceutical intermediates, cosmetic raw materials, and biological research, establishing themselves as a core raw material in high-end biochemistry.
2. Core Product Efficacy
The core efficacy of NR centers on regulating NAD⁺ levels, with high biological activity, strong safety, and wide applicability:
- Regulate NAD⁺ Levels: As an efficient NAD⁺ precursor, NR penetrates cell membranes to gently increase intracellular NAD⁺ concentrations, compensating for age-related NAD⁺ loss and providing energy support for cellular metabolism.
- Cell Protection & Anti-aging: NR participates in DNA repair and oxidative stress regulation, eliminates free radicals, reduces cell damage, delays aging, and improves cell vitality.
- Improve Metabolic Functions: NR regulates mitochondrial function, promotes fat decomposition and energy metabolism, relieves fatigue, enhances stamina, and supports R&D of sports nutrition and anti-fatigue products.
- Neuroprotective Effect: NR crosses the blood-brain barrier, nourishes nerve cells, improves cognitive function and memory, and helps prevent neurodegenerative injuries.
- Anti-inflammatory & Antioxidant: NR inhibits inflammatory factor release, enhances antioxidant capacity, reduces tissue damage, and boosts immunity.
3. Core Process Advantages (Maintain’s Exclusive Enzymatic Technology)
NR is mainly produced by three methods. Maintain Biotech’s enzymatic synthesis technology breaks traditional bottlenecks with significant advantages:
(1) Traditional Chemical Synthesis Method
Prepared via chemical condensation using nicotinamide and ribose derivatives, this method requires large amounts of organic solvents and strong acid-base catalysts. Disadvantages include low purity (≤95%), high impurities, significant three-waste emissions, harsh reaction conditions, high costs, and poor batch stability.
(2) Microbial Fermentation Method
Synthesized through microbial metabolism, this method avoids organic solvents but has obvious limitations: low product concentration, low yield (≤60%), long fermentation cycle (7-10 days), unstable purity, and complex purification, making large-scale production difficult.
(3) Maintain’s Exclusive Enzymatic Synthesis Process (Recommended)
Adopting an exclusive dual-enzyme one-pot method, NR is synthesized from nicotinamide and purine nucleosides in a mild, ambient temperature and pressure, full aqueous phase system. Advantages:
- Eco-friendly: No organic solvents or three-waste emissions, avoiding catalyst residue risks, suitable for high-end scenarios.
- High Purity & High Yield: Nicotinamide conversion rate ≥99%, product purity up to 99.5%+, impurities far below international standards, reducing costs significantly.
- Stable Process: Mild reaction conditions (25-30℃, pH 6.0-7.0), full traceability, minimal batch differences, suitable for large-scale production.
- Safe & Residue-free: Complies with international certifications like FDA GRAS, suitable for high-end dietary supplements and pharmaceutical raw materials.
- Strong Customization: Flexible customization of powder crystal form, bulk density, particle size, pellet processing, and formula customization to meet personalized needs.
