What is Spermidine?
Spermidine is a crucial compound aiding in cellular functions. It’s part of polyamines, contributing to various biological processes within the body. Spermidine plays an essential role in maintaining cellular homeostasis and promoting cell growth.
Overview of polyamines
Polyamines are crucial for cell growth, division, and health. They maintain cellular homeostasis, aid in cell repair, and remove damaged cells through autophagy. With age, our spermidine levels decrease.
These molecules also protect DNA from damage and are vital in creating new proteins. This protects against diseases and slows aging. Eating spermidine-rich foods boosts polyamine levels in the body, promoting health.
Role of spermidine in cellular functions
Spermidine is crucial for cell health. It starts autophagy, a process that cleans out damaged cell parts, helping cells function better and reducing inflammation. This compound boosts mitochondria, the cell’s power source.
It also creates reactive oxygen species (ROS) to activate ATM protein. This protein helps repair DNA damage and supports cell recovery processes. Spermidine plays a key role in protecting against age-related diseases and encourages cellular renewal.
How is Spermidine Absorbed in the Body?
The body absorbs spermidine mainly in the small intestine. It then spreads through systemic circulation to reach different parts of the body.
Absorption in the small intestine
Spermidine from food enters our bodies in the small intestine. Intestinal epithelial cells use a polyamine transport system for this. This process ensures spermidine reaches essential internal areas.
After consuming spermidine-rich foods, its levels rise significantly in the duodenum and jejunum, reaching millimolar concentrations. Moreover, blood plasma levels increase to 10–20 µM post-meal.
Through the gut’s efficient system, a significant portion of dietary spermidine enters our bloodstream.
Distribution through systemic circulation
After spermidine gets absorbed in the small intestine, it travels through the systemic circulation. As it does this, dietary spermidine is converted into spermine before entering the bloodstream.
Spermine might be the primary form of transportation for spermidine in the body.
Following absorption in the small intestine, dietary spermidine transitions into systemic circulation as metabolized to spermine.
Factors Affecting Spermidine Absorption
In the small intestine, spermidine absorption occurs. After that, it moves through the body’s circulation system.
Influence of diet and fasting
Diet greatly affects spermidine intake. European countries average 10-15 mg/day of spermidine consumption, with cheddar cheese containing around 200 mg/kg and mushrooms about 90 mg/kg.
Fasting before chemotherapy may also enhance efficacy by inducing autophagy.
Fasting prior to chemotherapy could lead to better outcomes through boosting autophagy. In European countries, people typically consume 10-15mg of spermidine per day – foods like cheddar cheese contain approximately 200mg/kg while mushrooms have around 90mg/kg.
Role of the intestinal microbiota
The intestinal microbiota, the diverse community of microorganisms living in our gut, plays a crucial but not fully understood role in spermidine metabolism. While research has shown that probiotic bifidobacteria can increase levels of spermine – another important polyamine – they do not have the same effect on spermidine levels in feces.
This indicates that there is a complex interplay between gut bacteria and the metabolism of different polyamines like spermidine within the body.
Through ongoing studies and research, scientists are working to unravel the intricate relationship between these intestinal microorganisms and how they impact the absorption and distribution of spermidine within our bodies.
These insights could potentially lead to significant advancements in understanding how dietary interventions or targeted modulation of gut microbiota might influence cellular processes related to polyamine metabolism, with potential implications for overall health and aging-related conditions.
Presystemic conversion of spermidine
Spermidine gets absorbed into the body and turns into spermine in enterocytes or during hepatic first-pass metabolism. When you consume dietary spermidine, it changes pre-systemically into spermine.
In simple terms, when you eat foods rich in spermidine or take supplements, your body converts the spermidine to another compound called “spermine” before it enters your systemic circulation.
This presystemic conversion occurs in your intestines or during its first pass through the liver. So, the dietary intake of spermidine has a direct impact on the levels of both spermidine and spermine in your body.
