NAD+ (500mg / 1000mg)

Price range: $79.00 through $119.00

Available sizes: 500mg / 1000mg

NAD+ (500mg / 1000mg)

  • Chemical name: nicotinamide adenine dinucleotide (NAD+)
  • A coenzyme present in every living cell and a central carrier of electrons in metabolism
  • Widely studied in cellular-energy and longevity research

Mechanism: NAD+ shuttles electrons in redox reactions across glycolysis, the TCA cycle and oxidative phosphorylation, and is a required substrate for sirtuin and PARP enzymes. It is studied for roles in mitochondrial energy production, DNA-repair signaling and the age-related decline in cellular NAD+ levels.

Description

NAD+ Overview

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell and one of the most important molecules in cellular metabolism. It is a central subject in energy-metabolism and longevity research due to its declining levels with age.

Central Role in Energy Metabolism

NAD+ acts as an electron carrier in the redox reactions of glycolysis, the TCA cycle and oxidative phosphorylation, making it essential to the production of cellular ATP — a core focus of bioenergetics research.

Sirtuin and PARP Activity

NAD+ is a required substrate for sirtuins and PARP enzymes, which regulate DNA repair, gene expression and stress responses. Research studies how NAD+ availability governs these longevity-associated pathways.

Aging and NAD+ Decline

Cellular NAD+ levels decline with age, and research investigates how restoring NAD+ influences mitochondrial function, metabolic health and age-related cellular changes.

A note on NAD+ purity. NAD+ is inherently unstable and is typically present alongside its own degradation products — ADP-ribose, nicotinamide, NMN and AMP. This is expected for the compound rather than a sign of contamination, which is why NAD+ assays below the purity figures seen for our stable peptides. The lab notes this directly on the certificate.
