NAD+ – Research-Grade Coenzyme | 500 mg | Liquilabs Certified

NAD+ (Nicotinamide Adenine Dinucleotide) is one of the most fundamental coenzymes in mammalian biology, central to cellular energy metabolism, DNA repair, and longevity-associated signaling. For researchers in the Netherlands, Regenorix batch RGXNAD500-2602-01 delivers 500 mg of research-grade NAD+ with full independent analytical certification from Liquilabs.

What is NAD+?

NAD+ is a dinucleotide coenzyme found in every living cell, functioning as an essential electron carrier in cellular respiration and as a substrate for a wide range of enzymes including sirtuins (SIRT1-7), PARPs (poly ADP-ribose polymerases), and CD38. NAD+ levels decline with age in multiple tissues, making its study critical to understanding the molecular biology of aging and metabolic decline.

Research applications include:

• Cellular energy metabolism and mitochondrial respiration studies
• Sirtuin (SIRT1, SIRT3) activation pathway research
• PARP enzyme substrate studies in DNA repair models
• NAD+/NADH redox balance research
• CD38 enzyme activity and NAD+ metabolism research
• Age-associated metabolic decline and longevity pathway studies
• Caloric restriction mimicry research models

Independent Lab Verification — Batch RGXNAD500-2602-01

Certified by Liquilabs s.r.o., 23 February 2026:

• Purity: 94.3% (HPLC — NAD+ Peptide Screening)

Research Applications

NAD+ is indispensable in research into the molecular mechanisms of aging. As a substrate for sirtuins and PARPs it plays a central role in epigenetic regulation, genomic stability, and mitochondrial health. The well-documented decline of NAD+ levels with age makes it one of the most researched molecules in longevity science over the past decade.
