Livagen
Summary
Humanin is a mitochondria-derived peptide (MDP) encoded in the 16S rRNA region of the mitochondrial genome. It protects neurons and other cells from apoptosis, improves insulin sensitivity, and declines significantly with age. HNG (S14G-Humanin) is a synthetic analog with 1000x greater potency.
Livagen is a dipeptide bioregulator (Lys-Glu) developed by Professor Vladimir Khavinson, tissue-specific for the liver and thymus. It supports hepatocyte function, promotes liver cell regeneration, and modulates immune function via thymic activity. Research suggests benefits in chronic liver disease, hepatic aging, and immune restoration following liver damage.
