Vesugen- Summary
- Spermidine is a naturally occurring polyamine found in all living cells, with exceptionally high concentrations in wheat germ, aged cheese, and human sperm. It is the most studied autophagy-inducing dietary compound, shown to extend lifespan across multiple species and reduce cardiovascular and cognitive aging.
- Vesugen is a tripeptide bioregulator (Lys-Glu-Asp) developed by Professor Vladimir Khavinson, tissue-specific for blood vessels and the vascular endothelium. It supports endothelial cell function, promotes vascular wall integrity, and is studied for atherosclerosis prevention, vascular aging, and cardiovascular health maintenance. It is one of the more broadly applicable Khavinson bioregulators given the ubiquity of vascular tissue.
- Half-Life
- ~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
- Short (minutes); sustained gene-regulatory effects
