What is the function of spermidine?
Spermidine is known to regulate plant growth, assisting the in vitro process of transcribing RNA, and inhibition of NOS. Also, spermidine is a precursor to other polyamines, such as spermine and thermospermine, some of which contribute to tolerance against drought and salinity in plants.
What is the meaning of spermine?
spermine. / (ˈspɜːmiːn, -mɪn) / noun. a white or colourless basic water-soluble amine that is found in semen, sputum, and animal tissues; diaminopropyltetramethylenediamine.
Is sperm a spermidine?
A new study in Nature Medicine shows that spermidine—a chemical found in semen—prolongs the lives of mice. It also did wonders for their hearts: The rodents that consumed it had lower blood pressure, lower rates of cardiac hypertrophy, and reduced risk of diastolic heart failure.
What foods have the most spermidine?
Spermidine content was high in dry soy bean, chicken liver, green peas, corn, shell fish, and blue cheese. A high content of spermine was found in most of the meat products (like sausages, pork, chicken, and turkey), some vegetables (like pumpkin), and cheese.
Where is spermine found?
Spermine is a polyamine, a small organic cations that is absolutely required for eukaryotic cell growth. Spermine, is normally found in millimolar concentrations in the nucleus. Spermine functions directly as a free radical scavenger, and forms a variety of adducts that prevent oxidative damage to DNA.
How does spermine work?
In the body, spermidine is created from its precursor putrescine. It is the precursor for another polyamine called spermine, which is also important for cellular function. Spermidine and putrescine are known to stimulate autophagy. A system that breaks down waste inside cells and recycles cellular components.
What is the sperm liquid called?
semen
The seminal vesicles and prostate gland make a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated.
Is spermidine safe to take?
The data demonstrate that spermidine supplementation using a spermidine-rich plant extract is safe and well-tolerated in mice and older adults. These findings allow for longer-term intervention studies in humans to investigate the impact of spermidine treatment on cognition and brain integrity.
Does cooking destroy spermidine?
In meat subjected to a cooking process involving a large amount of water (stewing and boiling), no significant losses of spermidine and spermine were observed either (23, 53).
Is it safe to take spermidine?
There are currently no known side effects from the intake of spermidine. Countless trials and scientific studies have already been conducted on this subject and the results show the full tolerance of this natural ingredient by our body.
Does meat contain spermidine?
Meat and its derivatives may contain high levels of spermidine and spermine, particularly the latter. Spermine values >148 nmol/g have been described in samples of beef, pork, chicken, cured ham, and sausages, without significant differences between fresh meats and derivatives (37, 63, 76, 77).
Does spermidine have side effects?
There are no known adverse side effects from spermidine supplementation. There have been a number of studies conducted with it, and the results suggest that it is well tolerated.
Are spermidine supplements safe?
How much spermidine should you take?
1mg spermidine per day
spermidineLIFE® recommended dosage is 1mg spermidine per day, considered a maintenance dose of spermidine, safe to take daily for as long as you wish.
How much spermidine is in aged cheese?
The more mature the cheese, the more polyamines it contains. Spermidine is just like that. Mature cheese has an average of 10 mg of spermidine per 100 g of food, according to 2011 analyses. Scientists from Graz therefore attest to the ripened cheese a good effect for the heart, but also point out the high fat content.
Should I take spermidine?
Its ability to induce cellular autophagy and its anti-aging benefits is impressive and once considered only possible through prolonged fasting. Taking daily spermidine supplements as you age is a safe way to protect against age-related illnesses and promote holistic health.
Which mushroom has the most spermidine?
Spermidine was ubiquitous to mushrooms, with highest content in Black Shimeji (12.4 mg/100 g). The levels of spermidine in mushrooms classify them as high polyamines sources, which is valued due to its association with growth, health promotion and antioxidant properties.
