Choosing the best spermidine supplements
Finding the right supplement involves some nuance, and this holds true for most dietary supplements. That’s why understanding what to look for and what to avoid is essential. Below, we describe in detail the criteria that guided our choices and explain why each one matters.
| Bioavailability | Manufacturing | Safety | Dose |
| Formulations for enhanced delivery | cGMP-certification or similar | Third-party laboratory testing | Research-supported |
- Bioavailability. Bioavailability determines how well your body can absorb and use the compound. If a supplement has low bioavailability, you might not get as much of the active ingredient delivered to the target areas to have an effect. In putting together our list, we looked closely at the bioavailability of each supplement, including whether they use methods like liposomal technology or are specially formulated to improve compound absorption.
- Manufacturing. Manufacturing in cGMP-certified facilities means strict adherence to quality control, which is crucial for upholding high standards and preventing contamination. We searched for products that have cGMP or comparable quality certifications.
- Safety. Spermidine products that are third-party laboratory tested were a top priority for us. Such testing provides insights into product quality, safety, and labeling accuracy, which in turn helps consumers understand exactly what they’re purchasing, without company bias.
- Dose. Using doses supported by research is the best approach to achieving the desired benefits from a supplement. It not only maximizes the supplement’s potential efficacy but also minimizes the risks of any unwanted side effects.
How to choose the right spermidine supplement for you
In our search for the best spermidine supplements, we learned it was crucial to consider specific factors to compile a line-up that truly reflects the absolute best selections out there. Here's what we recommend looking into:
- Research the source and quality. Prioritize supplements derived from natural sources like that of wheat germ. Also, products with third-party certifications like GMPs or certificates of analysis (COAs) can be a good indicator of quality.
- Look for scientific backing. While spermidine is a relatively new area of study, products that reference or support their health claims with scientific evidence can offer more credibility.
- Inspect the ingredient label. It's important to check the list of ingredients in the supplement. Avoid products with unnecessary fillers, additives, or allergens that might not align with your dietary preferences or restrictions. Choose supplements with minimal, clean ingredients.
- Consider the price point. While cost shouldn't be the primary factor, it's important to assess the cost-effectiveness of different options. Compare prices per serving and consider any potential discounts or subscription offers for long-term use.
What is spermidine?
Spermidine is a major member of the biogenic polyamine group, which also comprises spermine and putrescine. Whether it's found naturally in foods or taken as a standalone supplement, emerging research suggests spermidine could have a positive impact on your health.
As an ingredient in biogenic polyamine supplements, spermidine plays a role in maintaining cellular balance and is also essential for cell growth.
Keeping your spermidine levels up throughout life might help support heart health and potentially contribute to a longer life. However, as we age, our natural levels of spermidine tend to drop, and studies suggest this decline could be linked to some age-related health issues.
Spermidine's anti-aging properties are largely tied to its effects on several biological processes, one in particular being autophagy. This intricate molecular mechanism facilitates cellular waste removal and promotes optimal cell functioning. By supporting autophagy, spermidine is believed to enhance cellular function.
Spermidine effectiveness: what science tells us
Spermidine plays an essential role in various cellular processes and acts as an antioxidant. What is particularly interesting is its newfound potential as a longevity supplement, especially when formulated in a liposomal delivery system. This system has the potential to increase the cellular permeability of the formulation, thereby enhancing the bioavailability of liposomal spermidine and making it worth considering.
This biogenic polyamine has been demonstrated in some emerging studies to have an effect on age-related conditions, potentially supporting heart health and cognitive function. Scientific studies on this autophagy-inducing agent have also demonstrated its protective effects against cognitive impairment in animal models.
Intriguingly, spermidine intake with food has shown some advantageous effects on aging. This discovery opens up an appealing possibility — employing a spermidine-rich diet to increase its levels in the human body. This approach shows promise as a strategy to foster healthy aging.
We must conclude that while spermidine shows promise as a natural compound with various potential health benefits, particularly in aging-related processes, evidence of this in humans is still emerging. More clinical studies are needed to fully elucidate its effectiveness.
Benefits of spermidine supplements
Although the research on spermidine is still in its early stages, supplements containing this compound may provide a variety of benefits. These could include promoting autophagy, reducing inflammation, supporting heart health, and possibly enhancing cognitive function.
- Induces autophagy. Autophagy is the main mechanism at the molecular level through which spermidine works. As we get older, this process tends to slow down, which is why adding bioactive compounds like spermidine to our diet can be so beneficial. It may help keep the cells functioning optimally and support healthy aging.
- Supports cardiovascular health. Research suggests spermidine may positively impact cardiovascular health. Animal studies have shown it can play a role in blood pressure regulation, support cardiac function, and promote better cardiovascular health overall.
- Reduces inflammation. Research supports spermidine’s anti-inflammatory properties, showing that it can regulate immune responses and reduce the production of pro-inflammatory molecules. These findings suggest that spermidine could be useful as a therapeutic compound for managing inflammation and supporting overall health.
- Enhances cognitive function. Believed to benefit cognitive function, spermidine has been shown in animal studies to potentially support memory and learning capabilities. These effects are thought to result from spermidine’s ability to trigger autophagy in the brain. This process is thought to facilitate the removal of protein aggregates and, in this way, promote better cognitive function.
Possible side effects of spermidine supplements
While available studies have not reported any side effects from short-term spermidine supplementation so far, it’s good to remember that, like with any supplement, they’re not completely free of potential risks. That said, when taken responsibly, spermidine is generally considered safe.
We still need more research to fully understand any possible side effects and the long-term safety of spermidine supplements. Despite the current status, ongoing clinical trials exploring supplementation of spermidine-rich plant extracts are reporting encouraging findings about their safety and tolerability.
Is it safe to take spermidine?
Yes, taking spermidine is considered safe. Spermidine is generally well-tolerated, whether consumed in supplement form or through dietary sources.
Now, if you are on specific medication, adding spermidine to your routine requires consideration. It's best to consult with a healthcare professional beforehand — they can ensure the new supplement aligns with your current health status and medication use.
Recommended dosage of spermidine supplements
As of now, a universal standard dosage for spermidine supplements hasn’t been established. However, evidence suggests that taking up to 15 mg daily is generally well-tolerated with no reported side effects.
While ongoing research is still needed to pinpoint the ideal dosage and fully understand spermidine’s effects, sticking to the recommended amount on the supplement packaging is the recommended approach. Also, remember that eating a balanced diet with spermidine-rich foods like wheat germ, soybeans, and certain fruits can help you get this compound naturally.
How do I know if spermidine supplements work?
Figuring out whether spermidine supplements are effective can be subjective, but there are still several signs to watch for. Start by keeping track of specific health goals you had when you began taking the supplements.
If you notice improvements like more energy, better memory, or fewer signs of aging, that could be a good sign that the supplements are having a positive effect. It’s also useful to monitor certain biomarkers, such as blood pressure, cholesterol, and inflammation levels, since spermidine is linked to regulating these.
Remember, everyone’s response to supplements can be different. It is advisable to consult with a healthcare professional who can guide you through the process and, if necessary, conduct relevant tests. They can also help you interpret any changes you notice and decide if spermidine is right for your needs.
Spermidine-rich foods
Present in all tissues of the human body and also found in plants and other dietary sources, spermidine can be added to your diet through specific foods. Here are some excellent choices that are high in spermidine:
| Food category | Specific foods | Range of average spermidine content |
| Cereal | Rice, wheat germ, white bread | 2.8–2,437 nmol/g |
| Legumes and soybean products | Chickpeas, lentils, peas, white beans, red kidney beans, soybean, soybean sprouts, soybean milk, tofu, soy sauce, miso | 1.0–1,425 nmol/g |
| Vegetables | Broccoli, cabbage, cauliflower, carrot, celeriac, courgette, cucumber, eggplant, green beans, green pepper, lettuce, mushroom, onion, potato, spinach, tomato | 6.9–398 nmol/g |
