Spermidine- Summary
- Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.
- 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.
- Half-Life
- Short (minutes); gene-regulatory effects persist longer
- ~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks

- Key Benefits
- Cardioprotective effects on myocardial tissue
- Normalization of cardiomyocyte protein synthesis
- May improve cardiac rhythm and conduction
- Support for recovery from ischemic cardiac events
