Thymic peptides (thymalin, thymosin α1) PARP-1 upregulation, immune modulation, Nrf2 pathway activation Multiple RCTs showing 25–35% reduction in DNA damage biomarkers (comet assay, 8-OHdG) over 8–12 weeks Aging research, radiati…
Researchers investigating NAD+ and DNA repair pathways use multiple strategies to modulate NAD+ availability. The table below compares precursor supplementation, enzyme modulation, and peptide interventions. NAD+ Precursors (NR, …
Thymalin Thymic immune restoration; upregulates OGG1, XRCC1 Base excision repair (BER) + immune surveillance 35–40% thymic mass restoration in aged rats (Biogerontology, 2018); increased DNA repair gene expression Subcutaneous in…
Not all peptides that claim to support DNA integrity work the same way. Some activate repair enzymes directly. Others reduce the damage load by suppressing upstream stressors. Others still enhance immune clearance of cells that h…
