NAD⁺ (Nicotinamide Adenine Dinucleotide) is one of the most extensively studied coenzymes in modern biology. Functioning as a central metabolic regulator, it participates in over 500 enzymatic reactions from mitochondrial energy production to epigenetic gene regulation via sirtuins. BPeptide’s NAD+ 1000mg is produced under strict GMP conditions and verified to ≥99% purity by independent HPLC and mass spectrometry analysis.
Cellular Energy Production
NAD⁺ is the primary electron carrier in mitochondrial oxidative phosphorylation, driving ATP synthesis at the cellular level.
DNA Repair Mechanisms
Serves as the obligate substrate for PARP enzymes, which detect and repair single and double strand DNA breaks.
Sirtuin Activation
NAD⁺ is a required co-substrate for all seven sirtuins (SIRT1–SIRT7), the protein deacylases central to metabolic regulation and longevity research.
Neurological Research
Preclinical models suggest NAD⁺ repletion supports neuronal bioenergetics and may have implications in neurodegeneration research.
All BPeptide products are supplied with a full Certificate of Analysis (CoA) from an accredited third party laboratory. This ensures reproducibility across research batches. Each vial is packaged under nitrogen in amber glass to prevent oxidative degradation during transit and storage.
