  • Mushrooms: All edible mushrooms contain spermidine, especially shiitake and porcini varieties.

  • Aged foods: As foods age and ferment, spermidine levels increase. This includes aged cheeses, natto, miso, soy sauce, and cured meats.

  • Legumes: Lentils, beans, and peas are packed with spermidine.

  • Seafood: Anchovies and sardines are especially high in spermidine, with over 30 mg per 3 ounce serving.

  • Cruciferous veggies: Broccoli, cauliflower, kale, and Brussels sprouts provide a healthy dose of spermidine.

While you can get spermidine through diet alone, supplements are also available. The typical dosage ranges from 250 to 800 mg, 1-3 times per day. As with any supplement, check with your primary care provider first, especially if you are on any medications. Side effects appear minimal but may include digestive issues in high doses.

Spermidine is a natural compound with significant health benefits, especially for brain and heart health as well as longevity.

Both dietary sources and supplements can help increase your levels and support overall wellness. Why not give this anti-aging supplement a try?

The Anti-Aging and Longevity Benefits of Spermidine

Spermidine Provides Anti Aging

Spermidine promotes longevity. It is an anti-aging supplement that can help delay the onset of age related diseases, support immune cells, improve longevity and overall health as you get older. Here are some of the main benefits of spermidine:

Healthy aging

Spermidine may help slow down age-related mental and physical decline. Studies show spermidine supplements can prolong lifespan in animals by up to 25% by reducing cell death, improving cellular renewal and slowing the aging process.

Though more research is needed, spermidine shows promise as an anti-aging supplement for humans.

Slow cardiovascular disease

Spermidine can improve heart health and reduce the risk of cardiovascular disease. It helps lower high blood pressure and decreases inflammation in the arteries and blood vessels. Spermidine may also help prevent atherosclerosis by reducing plaque buildup. All of these effects can support better circulation and a healthy heart.

Cancer prevention

Some research indicates taking spermidine may help prevent certain types of cancer. It seems to inhibit the growth of cancer cells and trigger cancer cell death.

Spermidine is being studied as a potential supplement for cancer prevention and even as an adjunct to cancer treatment. The results so far are promising but ongoing research is still needed.

You can get spermidine from foods like aged cheese, mushrooms, soy products, and whole grains. However, to get therapeutic doses for health benefits, spermidine supplements may be needed.

Spermidine supplements are considered very safe for most adults with few side effects. However, as with any supplement, you should talk to your healthcare provider first, especially if you are on any medications.

Spermidine is an exciting anti-aging supplement that may help support longevity, heart health, and cancer prevention.

Though more research is still needed, the potential benefits of spermidine are promising. With the right diet and supplements, spermidine could be a key to living a longer, healthier life.

How Spermidine Supports Heart Health

Heart Health

Spermidine may help support your heart health in several ways. This longevity supplement can help lower blood pressure, reduce inflammation in the cardiovascular system, and possibly even decrease plaque buildup in arteries.

Lower Blood Pressure

Studies show spermidine supplements may help lower blood pressure by relaxing blood vessels and improving their flexibility and function.

High blood pressure is a major risk factor for heart disease, so keeping your numbers in a healthy range is important for your heart health.

Reduce Inflammation

Spermidine acts as an antioxidant in the body, helping to reduce inflammatory responses in the body especially the heart and blood vessels.

Chronic inflammation is damaging to the cardiovascular system over time and can lead to atherosclerosis, or plaque buildup.

By reducing inflammation, spermidine may help prevent plaque buildup and keep your arteries clear.

Inhibit Plaque Formation

Some research indicates spermidine may help inhibit the oxidation of LDL or “bad” cholesterol, which can lead to plaque formation in arteries.

Oxidized LDL is more likely to build up on artery walls. Spermidine may help block this oxidation process, thereby slowing the progression of atherosclerosis.

While more research is still needed, spermidine shows promise as a supplement that can support heart health through various mechanisms.

When taken regularly over the long term, spermidine may help lower heart disease risk by promoting healthy blood pressure, reducing inflammation, and inhibiting plaque buildup.

The Role of Spermidine in Cancer Prevention

Cancer Prevention

Spermidine shows promising results as an anti-cancer agent. Studies suggest it may help prevent and slow the growth of certain cancers. Here’s how:

Inhibits cell proliferation

Spermidine regulates cell growth and division. It helps ensure that cells don’t grow and replicate out of control, which can lead to tumor formation.

Spermidine seems to inhibit distinct pathways involved in cell proliferation and encourage programmed cell death in precancerous and cancerous cells.

Reduces inflammation

Chronic inflammation is a risk factor for cancer. Spermidine exhibits anti-inflammatory effects that may help lower cancer risk.

It suppresses the production of pro-inflammatory cytokines and other inflammatory mediators in the body. Reduced inflammation, in turn, makes cells less susceptible to DNA damage and mutations that can trigger cancer development.

Enhances autophagy

Autophagy is the process by which cells break down and recycle their own components. Spermidine enhances autophagy, which helps remove dysfunctional cell parts and waste products.

These complex interactions are important for preventing the buildup of harmful proteins and damaged organelles that can lead to cancer.

Impaired autophagy is linked to increased cancer risk, while enhanced autophagy may have protective effects.

Protects against DNA damage

Spermidine helps safeguard cells against DNA damage that can cause cancer. It seems to activate DNA repair pathways and antioxidant systems that protect cells from harmful free radicals and oxidative stress.

DNA damage, if left unrepaired, is a major driver of cancer initiation and progression. By supporting DNA repair and antioxidant defenses, spermidine may help stave off genetic mutations that lead to cancer.

In summary, spermidine shows promising anti-cancer potential due to its ability to regulate cell growth, reduce inflammation, enhance autophagy and protect DNA.

While more research is needed, spermidine may one day prove useful as an adjunctive treatment for cancer prevention and control.

Spermidine Supplements: Dosage and Safety


Spermidine supplements come in capsule or powder form and the typical dosage is between 200 to 800 mg per day, split into two or three doses. Always start with a lower dose and gradually increase to find what works for you, based on your body weight and sensitivity.


Spermidine supplements are considered very safe for most adults with no known serious side effects. However, as with any supplement, there are some precautions to keep in mind:

Check with your healthcare provider first if you are on any medications, as spermidine may interact with some drugs.

Start with a low dose and slowly increase to allow your body to adjust. This minimizes the risk of digestive issues or headaches.

Spermidine may lower blood pressure, so check with your healthcare provider if you have hypotension or are on blood pressure medications.

Spermidine could affect blood sugar levels, so people with diabetes should be monitored.

It is not recommended for pregnant or breastfeeding women due to lack of safety data.

While spermidine shows promise as an anti-aging supplement, more research is still needed to fully understand its effects, especially long-term use. As with any supplement, it may not suit everyone.

The key is to start low and slow and listen to your body. The potential benefits of spermidine for longevity, heart health and cancer prevention make it worth considering under guidance from your healthcare provider.


So there you have it, the lowdown on spermidine and why you should make it a part of your daily routine.

This longevity supplement has been shown to have some incredible effects on aging, heart health, and even cancer prevention.

While the research is still developing, the potential benefits seem too significant to ignore.

The best part is spermidine occurs naturally in foods you already enjoy, and supplements provide an easy way to boost your intake.

Talk to your healthcare provider about adding a spermidine supplement to support your health and wellness goals.

At the very least, fill your plate with spermidine-rich foods like broccoli, mushrooms, soybeans, and almonds. Your cells will thank you, and you’ll be investing in a long, vibrant future.
