Bronchogen- 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.
- Bronchogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Leu) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It is a tissue-specific bioregulator designed for the bronchi and lungs, promoting normalization of bronchial epithelial cell function. Research suggests benefits for respiratory health, protection against pulmonary aging, and support for bronchopulmonary conditions.
- Half-Life
- ~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
- Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
- Admin Route
