What is

NAD+

?

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell, essential for energy production and cellular metabolism. It helps repair DNA, regulate cellular stress, and maintain mitochondrial function. NAD+ is studied for its potential to improve overall cellular health, making it key in longevity research.

Frequently asked questions

Products from Direct Peptides do not include usage instructions, as they are strictly for in vitro research and prohibited by law for human or animal use. Misuse or unlawful application will result in permanent denial of service.

Each vial contains exactly what’s shown on the label. For example, a 10mg vial has exactly 10mg of lyophilized peptide. Researchers can divide it into smaller portions—like four 2.5mg measurements—but the total amount remains 10mg.

Peptides are supplied as lyophilized powder. They do not come reconstituted, and any extra supplies must be sourced separately for research applications.

In lyophilized powder form, peptides stay stable for up to 2 years. After reconstitution, it should be refrigerated and is generally stable for up to 2 months.

NAD+ Overview

Nicotinamide adenine dinucleotide (NAD⁺) is a naturally occurring coenzyme central to redox reactions, energy metabolism, and cellular signaling. In laboratory and preclinical models, NAD⁺ has been studied for its role in mitochondrial function, DNA repair, and regulation of cellular resilience. Research continues to explore its influence on sirtuin activation, oxidative stress response, and metabolic pathways.

Verdin E. (2015).

NAD+ History

NAD+ was first identified in the early 20th century during research into fermentation and cellular respiration. Its structure and biochemical role were later clarified, establishing it as a key coenzyme in metabolic and enzymatic reactions. In recent decades, research has expanded to its involvement in DNA repair, aging biology, and cell survival pathways, with growing use as a research tool in models of metabolism and stress response.

NAD+ Research Findings

NAD+ has been investigated in metabolic, cellular, and systemic models, with research highlighting its role in energy metabolism, mitochondrial function, and cellular repair processes. Studies have also examined its influence on oxidative stress, DNA repair, and overall cellular resilience in preclinical settings.

Key Areas of Research:

• Metabolic: energy production, mitochondrial function

• Cellular: DNA repair, oxidative stress, viability

• Systemic: protection, recovery, resilience

Together, these findings suggest broad experimental potential for NAD+ in supporting cellular and systemic biology. By engaging core metabolic pathways and influencing repair and stress responses, NAD+ provides a versatile platform for research into energy regulation, cellular recovery, and systemic health in laboratory models.
