At Intrinsic Peptides, we’re committed to offering cutting-edge peptides and nutraceuticals designed to enhance your health from the inside out. One of the most powerful and talked-about compounds in the world of anti-aging and cellular health is NAD+ (Nicotinamide Adenine Dinucleotide)—and we’re proud to offer it in its most pure and bioavailable form.

🧬 Overview of NAD⁺

Nicotinamide adenine dinucleotide (NAD⁺) is a vital coenzyme present in every living cell. It plays a central role in redox reactions, transferring electrons within cellular metabolism. NAD⁺ serves as a cofactor for multiple enzymes involved in energy production, DNA repair, and stress response, making it a focal point of modern cellular and longevity research.

🔋 Core Biological Functions Under Investigation

Cellular Energy Metabolism (ATP Synthesis):
NAD⁺ participates in glycolysis, the Krebs cycle, and oxidative phosphorylation, acting as an electron carrier essential for ATP production. Researchers examine how fluctuations in NAD⁺ availability affect mitochondrial efficiency and overall energy metabolism.
DNA Repair & Gene Regulation:
NAD⁺ serves as a substrate for PARPs (poly-ADP-ribose polymerases) and sirtuins, enzymes involved in DNA repair, epigenetic stability, and genomic protection under stress.
Immune and Inflammatory Modulation:
Studies show NAD⁺ influences macrophage activity, cytokine expression, and inflammatory responses, making it a target for research into immune system regulation.
Neuroprotection and Cognitive Function:
Preclinical research has investigated NAD⁺ in neuronal resilience, axonal repair, and protection against oxidative damage, offering insights into mechanisms of neurodegeneration and brain aging.

⏳ Age-Related Decline in NAD⁺

Scientific evidence demonstrates that NAD⁺ levels naturally decline with age due to increased consumption by stress-response enzymes (such as PARPs and CD38) and reduced synthesis through the salvage pathway.

This decline is a major area of study in fields exploring cellular senescence, mitochondrial dysfunction, and metabolic slowdown associated with aging.

🔬 Research Areas of Interest

Researchers are actively exploring NAD⁺ precursors and delivery systems (such as NMN, NR, and direct NAD⁺ formulations) to better understand how restoring NAD⁺ levels may impact cellular metabolism, energy signaling, and repair mechanisms.

Key Research Findings and Areas of Ongoing Study:

🧠 Cognitive Function Models:

Investigations suggest NAD⁺ supports neuronal plasticity, mitochondrial biogenesis, and synaptic function in models of cognitive decline and neurodegeneration.

💪 Muscle Recovery & Cellular Repair:

NAD⁺-dependent enzymes such as SIRT1 and SIRT3 are linked to muscle cell regeneration, mitochondrial turnover, and endurance capacity in animal and in-vitro studies.

🔥 Metabolic Regulation:

Research has associated NAD⁺ restoration with improved insulin sensitivity, lipid oxidation, and glucose utilization, making it a key molecule in metabolic and obesity-related studies.

🌙 Healthy Aging & DNA Maintenance:

Through activation of sirtuins and PARPs, NAD⁺ has been shown to enhance genomic integrity and promote adaptive stress responses in models of cellular aging.

⚡ Mitochondrial Energy Support:

NAD⁺ availability directly impacts mitochondrial respiratory chain function, supporting sustained ATP synthesis and redox balance under metabolic stress conditions.

🧪 Summary for Researchers

NAD⁺ is an essential coenzyme that bridges energy metabolism, DNA repair, and longevity signaling pathways.

Its age-related decline has positioned it as a cornerstone of modern cellular and metabolic research, particularly in studies exploring mitochondrial health, neuroprotection, and metabolic optimization.
