7 Best Spermidine Supplements (2023) Reviewed and Compared

Never miss a glorious update - click here!

While not as discussed as much as resveratrol or NMN, spermidine is one of the most interesting and possibly effective supplements for longevity and health.

This polyamine (a fancy organic chemistry term, but I just used it to sound smart) has possibly the best origin story of any supplement ever.

Anthony Van Leeuwenhoek (the guy who invented the microscope) discovered it in the 1600s when he decided to put sperm, presumably his own, under a microscope and look at it.

Yes, that’s the actual story.

Fortunately, today we don’t derive spermidine from sperm. We derive it mostly from wheat germ, which is much easier to produce, for a lot of reasons I probably don’t have to say.

So here’s the T (as the cool cats say) on spermidine supplementation.

What Are The Health Benefits of Spermidine?

Simply, spermidine may lengthen our lifespan, which it has done in yeast, worms, mice, and human immune cells. For example, this study in Nature showed exactly that.

These types of experiments are a bit tricky to do on humans, as they take about a century, but there’s compelling research to suggest that it carries over.

Anti-Aging and Healthy Aging

As mentioned, this is what all the buzz of spermidine is about. Research has shown that our spermidine levels begins to decrease around age 25-30.  

Research indicates that our own spermidine levels start to decrease from approximately 25-30 years of age.

Other epidemiological research (that is, studies on populations), showed that people who ate more spermidine-rich foods averaged a life expectancy of five years longer.

Another recent study showed that many centenarians have spermidine levels similar to that of a young person, also suggesting that it plays a role in longevity.

As mentioned, spermidine has already increased the lifespan of other species.

Since “aging” is so broad, though, we’ve also seen other health and performance benefits from spermidine.

One concrete example, as shown in this study on humans, is that spermidine may help hair growth, particularly if the loss of hair is age-related

Improving Memory and Cognitive Health

A 3-month study showed that spermidine supplementation improved memory in older people with dementia.

Clinical trials on healthy older adults have also shown memory improvements. All of this suggests that spermidine supplementation may slow down cognitive decline.

Whether that translates to increased cognitive performance in younger, healthy people remains to be seen. It also remains to be seen whether this improves conditions like Parkinson’s and Alzheimer’s.

May Improve Cardiovascular Health

In mice studies, spermidine has been suggested to improve cardiovascular health. This has also carried over to human population studies, but we still don’t have good research on humans yet. Nonetheless, we’re investigating more whether spermidine could reduce the risk of cardiovascular disease.

One of the proposed mechanisms for this is that spermidine may increase the number of mitochondria in heart cells.

Spermidine supports cellular respiration, which leads to increased mitochondrial content in heart cells.

May Work as An Anti-Inflammatory

While this research is very early, a study on macrophages and zebrafish (sounds like a fun sudy) showed that spermidine reduced inflammation and oxidative stress. For this reason, it may be considered an antioxidant. While speculation, for similar mechanisms some proponents of spermidine say it may support the immune system.

lot of these benefits need more research. All of them, really. But they’re all pointing in a similar direction: if your goal is to live a longer, healthier live, a spermidine supplement may support you in that.

(As for how it does this, learn more about how spermidine works on a cellular level in the FAQ section.)

But, not all supplements are created equal.

In fact, most supplements are crap, because they’re not regulated by the FDA. So even if you’re excited about spermidine, make sure you grab it from a quality source.

Today we’re discussing the best spermidine supplements on the market.

Every product on our list is third-party tested, and many go well beyond this to ensure quality.

Best Overall: Oxford Healthspan Primeadine

Best Gluten-Free: Oxford Healthspan Primeadine Gluten-Free

1) Oxford Healthspan Primeadine

Check Lowest Price


What makes Primeadine stand out above the rest is that their spermidine is wholly food-derived from wheat germ extract. Now, in general, just because something is natural, doesn’t mean it’s better. However, with spermidine, there seem to be a few advantageous to the food-derived route. Just like eating carrots versus taking a multivitamin, the food-derived option contains a unique combination of other nutrients that make the carrot, simply, the superior option.

Primeadine also contains prebiotic fiber and resistant starch to support bacteria in the gut that produce spermidine. In that sense, they view their product as not just about exogenous spermidine, but about helping the body produce more spermidine naturally. This is the second component that stands out about Primeadine.

Third, Primeadine goes the extra step of cutting out the cheap omega-6 oil in wheat germ, so that it doesn’t go bad or become ineffective. This is surprisingly common with spermidine supplements.

Finally, their commitment to quality is top-notch. This product is made in an FDA-approved facility and their research and product development is backed by the University of Oxford. 

For all of these reasons, Oxford Healhtspan Primeadine is our #1 pick.

2) Renue by Science LIPO Spermidine

Renue by Science LIPO Spermidine stands out for a few reasons.

First, is the overall quality. Renue has a commitment to producing some of the best longevity products out there. All of their products are products in FDA-approved facilities. They even display their lab results of every batch, so you can ensure their products for purity.

Renue’s spermidine use a liposomal delivery mechanism to improve bioavailability.

This is when the spermidine molecules have a protective lipid coating that helps them survive our intense digestion environment and make it into our bloodstream.

While this may improve bioavailability, it means you won’t get some of the gut-lining effects that you might get with a product like Primeadine, which is the main reasons why we give Primeadine the slight edge. There’s also 

Next, Renue LIPO Spermidine is a great value. Because this is such a cutting-edge supplement, a lot of products are still very expensive. Renue’s product, in contrast, is more affordable, especially when compared per gram. With 4mg per serving, it has the best combination of quality and value.

For all of these reasons, Renue LIPO Spermidine is our #2 pick.

The one knock is that it’s a synthetic-derived product.

3) Longevity Labs SpermidineLife® Extra+

Check Lowest Price

In terms of overall quality, SpermidineLife® Extra+ from Longevity Labs is tough to beat.

Longevity Labs has an array of spermidine products developed in Austria. They use a specific, patented CelVio® complex that ensures a consistent and pure process. It’s also a natural manufacturing process, so their spermidine gets combined with other polyamines like spermine, as well as micronutrients, and doesn’t contain any synthetic ingredients. 

Overall, simply, it’s among the highest quality spermidine companies out there, and they have the patents, process, and awards to back it up.

Their “Extra+” version contains a higher dose than the original (which we’ll talk about next), with nearly twice the amount of spermidine. Still it’s less than 2mg of spermidine overall, making it half the dose of what Renue offers.

Nonetheless, Longevity Labs SpermidineLife® Extra+ is a top-quality product. If cost is not an issue for you, then start here.

The reality is, between our top three products, all are super reputable companies with great products. In a lot of respects, we’re splitting hairs, and you can’t go wrong with LIPO Spermidine, SpermidineLIFE, or Oxford Healthspan Spermidine. 

4) Longevity Labs SpermidineLife Original 365

This is the original SpermidineLife® product. It’s a bit less pricey than their other version, but its dose is also smaller, with only 1mg per serving.

5) Double Wood Supplements Spermidine

Check Lowest Price

Double Wood provides the highest dose at the least expensive upfront cost on our list. They’re also manufactured in the USA and have the testing results of every batch displayed on their site.

This makes it a great option to start out taking spermidine. However, bioavailability is a question, since it doesn’t have other mechanisms like the other products on our list so far. It’s also a synthetic spermidine. 

6) Oxford Healthspan Primeadine Gluten Free (Best and Only GF Option)

Check Lowest Price

Primeadine also comes in a gluten-free version. Because spermidine is typically derived from wheat germ extract, premium spermidine extracts typically contain gluten. This is the only exception from a high-quality brand.

It contains 1.2mg of plant-derived spermidine with the added ingredient nobiletin, which also may enhance autophagy.

Because it comes from different plants, it’s a naturally occurring source of vitamin D2, vitamin K, folate, vitamin B12, biotin, pantothenic acid, iron, and lutein.

For a gluten-free option, it’s by far your best bet.

How We Ranked

Here are the main factors that went into our rankings. Of course, what may be the best product varies from person to person depending on goals, budget, and more.

So take it all into consideration when making your decision.

Overall Quality

Some products contain various delivery mechanisms that can increase the bioavailability of spermidine, like Renue’s LIPO Spermidine, which has a protective liposomal layer around the spermidine molecule.

Others stand out in quality because they use a naturally-derived form of spermidine, like Oxford Healthspan Primeadine


Okay, absorption is a bit of a controversial subject when it comes to spermidine. All of the top products on our list have methods to increase absorption. Primeadine and SpermidineLife are whole-food derived, which may increase absorption.

Renue uses liposomal delivery, which may increase absorption, but has its drawbacks as well. In particular, the spermidine can’t go to work on supporting the gut lining.

Company Quality

We also weighed the strictness of the testing of the product, and the company’s commitment to longevity. For example, Spermidine Life is a company deeply involved directly with the research. There’s little doubt about the quality and efficacy of their products.


Of course, money is a factor for most of us. While I love Spermidine Life’s quality is much more expensive than other products.

Renue is #1 also because they find this perfect balance. They maintain very high quality and strict testing, while also lowering their prices to be more affordable, even if that means cutting into their own margins.

Spermidine Supplementation FAQ

How Might Spermidine Extend Lifespan and Slow Aging?

The most well-understood is spermidine’s ability to increase autophagy.

Autophagy is one of those fancy science words that nobody really understands, so it’s going to get its own question.

Okay, so what the heck is autophagy? And what does spermidine have to do with it?

Basically “increased autophagy” means that the cell’s clean-up crew is hard at work.

Imagine cells without any janitors, street cleaners, or good citizens picking up trash. This is a cell with low levels of autophagy. Now imagine that a cell is well-kept and constantly looked after by a team of workers. That’s a cell with high levels of autophagy. 

This is stimulated by a few well-known longevity pathways, like the suppression of mTOR.

Simply, research has shown that high levels of spermidine mean more autophagy.

Second, research has suggested that spermidine can adjust epigenetic expression. As the theory for longevity goes, part of what causes aging is genes we onced “expressed” when we were young, get suppressed as we age.

By turning back the clock on the gene expression, we can slow down (or even reverse) aging. Spermidine may enhance this, per recent studies.

Can You Get Spermidine From Food? Do I Need to Take It As a Dietary Supplement?

Yes. One study on the polyamine content of foods said, “Spermidine content was high in dry soybean, chicken liver, green peas, corn, shellfish, and blue cheese.” The Japanese soybean dish natto is a great option also, and you can get it at most boujie poke bowl places these days. 

Another option, instead of the standard supplement route, is to buy wheat germ. This is definitely a much more economical route, if you’re on a tight budget.

For example, you can buy this simple wheat germ product from Bob’s Red Mill for under 5 bucks. You’ll have to find a way to use it for cooking, but it contains ample spermidine.

Can You Take Spermidine Every Day?

Yes. In fact, almost all of the studies look at daily supplementation. Every product on the market suggests daily use, and there isn’t any downside to regularly taking it compared to sporadic use.

Is Spermidine Gluten-Free?

Because spermidine comes from wheat germ, most spermidine products on the market contains a small amount of gluten (usually no more than a few miligrams). Nonetheless, wheat germ-derived spermidine supplements are contraindicated if you ahve celiac disease.

If you need to avoid gluten, we recommend Oxford Healthspan’s Gluten-Free Spermidine.

What Does It Mean That Spermidine is a ‘Polyamine.’

This is a question for your organic chemistry professor, not me. But basically they’re not proteins, but they have amino groups, so chemically they have some stuff in common. More improtantly, polyamine synthesis is crucial for cell renewal, growth and repair, and that’s where spermidine comes in.

Does Spermidine Have Side Effects?

Research on humans has consistently shown the safety and efficacy of spermidine. It seems to be a super safe, simple supplement. (Remember, you get it from ordinary wheat germ.)

That said, it’s still relatively early in terms of research.

Where Can I Learn More About Longevity and The Aging Process?
