NAD⁺ Research Peptides: Mitochondrial Function and Cellular Aging
Introduction
NAD⁺ (nicotinamide adenine dinucleotide) is a vital coenzyme found in every cell, playing a central role in mitochondrial energy production, DNA repair, and cellular health. Its decline is closely linked to aging, metabolic dysfunction, and neurodegeneration.
In research, NAD⁺ and NAD⁺-boosting peptides have become critical tools for studying mitochondrial function, oxidative stress, and longevity pathways.

What Is NAD⁺?
NAD⁺ is a redox coenzyme involved in transferring electrons during metabolic reactions, such as glycolysis, the TCA cycle, and oxidative phosphorylation. It is essential for producing ATP — the cell’s energy currency.
Beyond its metabolic role, NAD⁺ is required for the activation of:
- Sirtuins (SIRT1–SIRT7) — enzymes involved in gene regulation and stress response
- PARPs — enzymes critical for DNA damage repair
- CD38 and CD157 — enzymes linked to immune function and inflammation
Why Is NAD⁺ Important in Aging and Disease Models?
As organisms age, NAD⁺ levels naturally decline due to increased oxidative damage, chronic inflammation, and enzymatic consumption (e.g., via CD38 overactivation).
NAD⁺ depletion leads to:
- Impaired mitochondrial ATP production
- Weakened DNA repair mechanisms
- Increased cellular senescence
- Chronic low-grade inflammation (“inflammaging”)
Replenishing NAD⁺ in experimental models restores mitochondrial function, enhances stress resistance, and improves survival rates in studies of aging and metabolic disease.
How NAD⁺ Is Studied in Peptide Research
NAD⁺ precursors like NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are often stacked with peptides like:
- GHK-Cu (wound healing, anti-inflammatory pathways)
- BPC-157 (angiogenesis and tissue protection)
- CJC-1295 DAC (GH axis support, metabolic rejuvenation)
- Thymosin Alpha-1 (immune modulation)
This stacking aims to optimize mitochondrial health, redox balance, and regenerative capacity in cell culture and animal models.
