Livagen
THE LIVER REVITALIZER
Lys-Glu-Asp-Ala
Livagen is a synthetic tetrapeptide bioregulator that can actually interact with your DNA to influence gene expression. It's been shown to activate genes in immune cells that may have become "silenced" with age. It may help restore youthful immune function and cellular repair capacity.

Chromatin research background
A 2002 paper by Khavinson, Lezhava and colleagues studied synthetic Livagen in lymphocytes from older donors. The work examined ribosomal genes and different forms of chromatin, the DNA-protein material in chromosomes. It provides a specific laboratory origin for Livagen's chromatin research, rather than evidence that the peptide selectively targets the liver.

Market evidence
Livagen product testing and COAs
We found certificates from some of the Livagen vendors we track. Based on the certificates our crawler found; vendors may publish more than we index. Research on this page describes the molecule. Vendor certificates concern particular market samples or batches; they do not change the research evidence or establish clinical safety, sterility, or suitability for use.
