Backed by science. Made with care.
Your cells experience approximately 100,000 DNA damages daily from environmental stressors, metabolic byproducts, and natural cellular processes. NAD+ (Nicotinamide Adenine Dinucleotide) functions as an essential coenzyme that powers your body’s DNA repair mechanisms, acting as a critical defense system against this constant genomic assault.
NAD+ serves as the primary fuel source for PARP (Poly ADP-Ribose Polymerase) enzymes, which act as rapid DNA damage sensors. When DNA breaks occur, PARP1 and PARP2 immediately detect these lesions and consume NAD+ to activate repair pathways through a process called ADP-ribosylation. This modification recruits specialized repair proteins to damage sites and facilitates base excision repair (BER), which fixes single-strand breaks and damaged DNA bases.
Research demonstrates that NAD+ is consumed at remarkable rates during DNA repair—activated PARP enzymes can utilize up to 80-90% of cellular NAD+ when responding to significant DNA damage. The enzyme also supports double-strand break repair through both non-homologous end joining (NHEJ) and homologous recombination pathways.
NAD+ levels naturally decline with age, reducing from optimal levels in youth by approximately 50% or more in older adults. This age-associated depletion leaves genetic material increasingly vulnerable to damage accumulation. Human tissue studies reveal strong negative correlations between NAD+ levels and age in both males and females, with corresponding increases in DNA damage markers.
As NAD+ depletes, PARP enzyme activity becomes compromised, impairing the cell’s ability to efficiently repair DNA damage. This creates a cycle where accumulated oxidative damage activates PARP enzymes, further depleting NAD+ stores and limiting the availability of this crucial molecule for cellular energy production and ongoing DNA repair.
NAD+ molecules work as cofactors in numerous biochemical reactions throughout your body, supporting mitochondrial health, cellular metabolism, and sirtuin activation—all processes that contribute to maintaining genomic integrity. These NAD+-dependent sirtuins (particularly SIRT1, SIRT6, and SIRT7) regulate DNA repair proteins, chromatin structure, and stress response pathways.image.jpgpmc.ncbi.nlm.nih
Scientific evidence indicates that maintaining adequate NAD+ levels supports the body’s natural capacity to detect DNA damage, activate repair mechanisms, and preserve chromosomal stability. Studies across multiple model systems demonstrate that NAD+ supplementation can enhance DNA repair capacity, reduce accumulated DNA damage, and support cellular function in the face of genotoxic stress.
