Spermidine is a naturally occurring polyamine that is found in a variety of foods, including soybeans, wheat germ, and mushrooms.
It has started to become widely popular because of Bryan Johnson Blueprint morning drink - The Green Hulk
While research on spermidine is still in its early stages, there is growing evidence to suggest that it may have a range of potential health benefits.
Improved Cardiovascular Health
One of the most promising health benefits of spermidine is its potential to improve cardiovascular health.
Several studies have found that spermidine can help to reduce blood pressure and protect against heart disease.
For example, a study published in the Journal of Hypertension found that supplementing with spermidine for 3 months led to a significant reduction in systolic blood pressure in people with hypertension.
Another study published in the Journal of the American College of Cardiology found that a diet rich in spermidine was associated with a lower risk of cardiovascular disease.
Another potential benefit of spermidine is its anti-aging effects. Spermidine has been shown to activate a process called autophagy, which helps to remove damaged or dysfunctional cells from the body.
This may help to slow down the aging process and reduce the risk of age-related diseases.
For example, a study published in the journal Nature Medicine found that supplementing with spermidine improved cardiac function and increased lifespan in mice.
Improved Cognitive Function
Spermidine may also have benefits for cognitive function. Animal studies have found that spermidine can enhance memory and cognitive function.
For example, a study published in the journal Neuroscience Letters found that supplementing with spermidine improved spatial learning and memory in rats.
Spermidine may also help to protect against neurodegenerative diseases such as Alzheimer's and Parkinson's.
A study published in the journal Autophagy found that spermidine protected against the accumulation of toxic proteins in the brains of mice with Alzheimer's disease.
Enhanced Immune Function
Spermidine may also have benefits for the immune system. Several studies have found that spermidine can increase the production of white blood cells, which are important for fighting infections.
For example, a study published in the journal Immunobiology found that spermidine increased the production of T cells in mice.
Protection Against Cancer
Finally, spermidine may have anti-cancer effects. Animal studies have found that spermidine can help to prevent the growth and spread of cancer cells.
For example, a study published in the journal Cancer Research found that spermidine inhibited the growth of colon cancer cells in mice.
While research on spermidine is still in its early stages, there is growing evidence to suggest that it may have a range of potential health benefits. These include improved cardiovascular health, anti-aging effects, improved cognitive function, enhanced immune function, and protection against cancer. However, more research is needed to fully understand the health benefits of spermidine and the appropriate dosages for different populations.
