Endoluten vs NAD+

Pineal-targeted peptide complex that modulates melatonin synthesis pathways and circadian gene expression. May help restore age-related decline in pineal activity and improve circadian rhythm regulation.

A short peptide bioregulator derived from pineal gland tissue, developed by the Khavinson Institute. Studied for circadian rhythm restoration, melatonin pathway support, and longevity — addressing the age-related decline in pineal gland function.

NAD+ is a coenzyme central to cellular energy metabolism, serving as an electron carrier in glycolysis, the citric acid cycle, and oxidative phosphorylation. It is also a required substrate for sirtuins (SIRT1–7) and PARP enzymes, which regulate DNA repair, gene expression, and mitochondrial biogenesis. NAD+ levels decline measurably with age; IV or subcutaneous delivery aims to restore intracellular pools more directly than oral precursors such as NMN or NR.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell, central to energy production, DNA repair, and sirtuin activation. While not a peptide in the traditional sense, it is widely administered by functional medicine and longevity providers via intravenous infusion or subcutaneous injection. Research interest centres on its role in mitochondrial health, cellular resilience, and neurological function as NAD+ levels decline with age.
