Spermidine is a naturally occurring polyamine that is found in all living cells. It is involved in many important cellular processes, including cell growth, differentiation, and death. Recent studies have shown that spermidine may have numerous health benefits, ranging from promoting brain function and heart health to supporting healthy aging and reducing the risk of age-related diseases. In this article, we will explore the science behind spermidine, its potential health benefits, and possible side effects and dosages.
The Science Behind Spermidine and How It Works in the Body
Spermidine is synthesized from the amino acid arginine by the body’s cells, and it is involved in many important cellular processes. It has been shown to regulate autophagy, a natural process of cell recycling and renewal that removes damaged and dysfunctional cellular components and promotes healthy cell function. Autophagy is critical for maintaining cellular homeostasis, and studies have linked its dysfunction to many age-related diseases.
One of the key mechanisms through which spermidine promotes autophagy is by activating a protein complex called mTORC1, which is involved in regulating cell growth and metabolism. When mTORC1 is activated, it inhibits autophagy, and when it is inhibited, autophagy is promoted. Spermidine has been shown to inhibit mTORC1, thus promoting autophagy and improving cellular health.
Recent studies have also suggested that spermidine may have potential anti-aging effects. In a study conducted on mice, spermidine supplementation was found to increase lifespan and improve cardiovascular health.
