In Plain English
A 4-amino acid peptide developed by Russian longevity researcher Vladimir Khavinson that supports the heart and immune system by acting as an "epigenetic switch" — entering cell nuclei and turning on genes that get silenced with age. Part of a family of organ-targeted bioregulators with decades of research in Russia.
Overview
Livagen is a synthetic tetrapeptide (Lys-Glu-Asp-Ala, KEDA) developed by Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology. It belongs to the family of peptide bioregulators — short peptides that act as epigenetic gene expression regulators in specific tissues. Livagen is classified as a cardiovascular and immune bioregulator, with Russian research demonstrating effects on cardiac function, lymphocyte activity, immune senescence reversal, and oxidative stress reduction. Used in some Eastern European clinical and research settings for cardiovascular support and immune restoration in aging populations.
Common Formats
- Lyophilized powder (injectable)
