Spermidine, a naturally occurring polyamine, has gained attention for its potential health benefits, including anti-aging properties and cellular regeneration. A common question is, can women take Spermidine? Based on our research, the answer is yes. Women can benefit from Spermidine's ability to enhance autophagy, the body's cleaning process of damaged cells. 


Let's explore the safety, benefits, and considerations for women considering incorporating Spermidine capsules into their health routines.

What Is Spermidine?

Spermidine is a naturally occurring polyamine present in all living organisms. [1


Polyamines like Spermidine play a crucial role in cellular processes. They support cell growth, differentiation, and survival. Foods high in Spermidine include wheat germ, soybeans, and aged cheese.


Role of Spermidine in the Body

Spermidine helps your body trigger a natural process called autophagy, where your body clears out damaged cells and makes new ones. This process is essential for overall cell health and may benefit aging. [2]

Health Benefits of Spermidine

Potential Spermidine health benefits include:


Cellular Health

Spermidine promotes autophagy, which helps remove damaged cellular components, thus supporting cellular health. Stimulating autophagy may contribute to anti-aging effects and help preserve cellular integrity as we age. [3]


Longevity

Observational studies show a link between higher intake of Spermidine-rich foods and longevity. Animal studies have shown lifespan extension, making Spermidine a promising compound for longevity research. [4]


Cognitive health

There is some interest in Spermidine and its ability to improve memory function. Animal studies show promising results. In human studies, the results have been varied. One double, blind randomized control study showed no improvement after 12 months of Spermidine at a dose of 1mg. Another study showed a positive impact on memory with higher doses. [5][6


While Spermidine shows promise in animal studies, human trials are limited and show conflicting results. More research is required to demonstrate whether Spermidine has any significant benefits.

How to Increase Your Spermidine Intake

There are a few things you can do to try to increase your Spermidine levels:


Take Supplements

Spermidine supplements, available in capsule or powder form, provide a convenient way to boost your intake, notably if your diet lacks Spermidine-rich foods.


Eat Spermidine-Rich Foods 

Soybeans, wheat germ, and mushrooms are naturally high in Spermidine. You can also increase your intake by consuming moderate amounts of whole grains, legumes, and certain fruits and vegetables.


Consume Fermented Foods

Fermentation enhances a food's Spermidine content, making foods like natto (fermented soybeans) and fermented cheeses excellent sources for increasing your Spermidine intake.

Safety & Recommended Dosage

Spermidine is generally safe when you consume it in dietary amounts. Research indicates no significant adverse effects in women using it as a supplement. However, pregnant and breastfeeding women should consult healthcare professionals before starting any new supplement. Individual reactions may vary, so monitoring for any adverse effects is essential. [7]


Studies using 1 mg have yet to show much promise, and researchers have suggested using higher doses in future studies to discover whether they garner better results. 


It's best to follow manufacturers' dosage instructions or consult a healthcare provider to determine the appropriate amount based on your individual health needs.

Potential Side Effects

Women taking Spermidine might experience side effects.


Short-Term Side Effects

Short-term effects of Spermidine are generally not seen. Spermidine itself is found in many of the foods we all consume daily. With that said, mild reactions to the source of Spermidine can be seen. For example, the best spermidine supplements use wheat germ as the source. Wheat germs naturally contain gluten, so those with gluten sensitivity may experience gastrointestinal side effects. With that said, this is generally mild, given that the amount of gluten is negligible. People with Celiac disease should avoid natural wheat germ-based spermidine supplements and opt for a synthetic form such as spermidine trihydrochloride.  

Long-Term Side Effects

Researchers are still studying the long-term effects of Spermidine, but current data suggest minimal adverse consequences. Ongoing research points to its safety over extended periods when people take it in recommended dosages (1-3 mg daily). Some theoretical concerns include potential alterations in gut microbiota; however, human studies have not conclusively documented these concerns. Regular consultation with healthcare professionals can help track any long-term changes and ensure the supplement remains beneficial.

Frequently Asked Questions

Is Spermidine safe for women?

Yes, Spermidine is generally considered safe for women when they take it in recommended amounts.


Does Spermidine increase testosterone in women?

No, there is no evidence suggesting that Spermidine increases testosterone levels in women.


Is Spermidine good for fertility?

Studies in mice have shown that spermidine supplementation improved egg quality. However, this has not been proven in humans, and there is not enough evidence to suggest that Spermidine is good for fertility at this stage. [8


Are there downsides to Spermidine?

Potential downsides to Spermidine include gastrointestinal discomfort and allergic reactions, although these side effects are rare.


What are the recommended daily dosages of Spermidine for women?

The recommended daily dosage of Spermidine is 5-10mg. This dosage promotes cellular health and autophagy. Low doses of 1-3mg are not effective in humans.


Should I take Spermidine supplements?

Consult a healthcare professional to determine if Spermidine supplements suit your health needs.


How does Spermidine promote hair growth?

Spermidine has been shown to promote hair shaft elongation and extend the anagen phase. Some anecdotal evidence from people who take spermidine supplements shows that their hair feels subjectively thicker. More research needs to be done to prove that Spermidine promotes hair growth. [9]  


What are the cardiovascular benefits of Spermidine?

A review published by Nature reported that research suggests: "Oral supplementation of a natural polyamine spermidine in rodent models of cardiovascular disease is associated with reduced cardiac hypertrophy, preserved diastolic function, and prolonged lifespan." This has not been proven in humans as yet." [10]


Does Spermidine enhance cognitive function?

There is a lot of interest in Spermidine's potential to enhance cognitive function and support brain health in those with cognitive decline. Animal studies show positive benefits in memory function. Human studies have shown conflicting results at the time of writing, with one trial showing benefit and another reporting no significant improvement (1 mg/day dose). Researchers are considering using higher doses of Spermidine in humans to see if they can yield better results.  [11][12]
