Anti-aging scientists consider Spermidine as one of the most promising autophagy-inducing agents.

Autophagy is the process in which cells clear out old dysfunctional proteins and organelles. This is important because the misfolded and damaged proteins trigger inflammatory processes which have been linked to several age-related diseases.

This interest has sparked an explosion in the number of Spermidine supplements available on the market. Given the abundant choice, it can be hard to know which Spermidine brand to invest in.

In this article, we’re going to do a deep dive into the best Spermidine supplements based on purity, quality, and effectiveness.

How to Choose a Spermidine Supplement

Before we get into it, we first need to go over the main things to look out for when deciding which Spermidine supplement to buy:

1) Natural vs Synthetic Spermidine

Natural Spermidine is sourced from plants such as wheat germ, buckwheat sprouts, or rice germ extract. Whereas synthetic Spermidine is made in a lab. You can easily tell them apart by looking at the supplement facts table. Synthetic Spermidine is labeled as “Spermidine Trihydrochloride”.

2) Dose

The dose of Spermidine from natural sources such as wheat or rice germ ranges from 1-10mg. On the other hand, synthetic Spermidine is often available at a higher dose of 10-25mg per serving. There is no official recommended Spermidine dose so you’ll need to decide this based on your goals.

3) Quality

The highest quality Spermidine supplements will avoid the use of artificial fillers and additives like magnesium stearate. Also, look out for whether the supplements are made in a GMP certified manufacturing facility. This certification will ensure that the manufacturers adhere to strict safety measures.

What is Spermidine?

Spermidine belongs to a group of three organic compounds called “polyamines”. Polyamines are found in all living cells and they play an important role in facilitating cell growth and DNA repair.

More recently, it’s been discovered one of these polyamines, Spermidine, has the ability to induce autophagy.

Autophagy is an essential cellular process whereby damaged organelles (i.e. mitochondria) and misfolded proteins are cleared out. It’s our cell’s very own recycling and waste management system.

Scientists have found that our cells’ ability to carry out autophagy declines with age. The build-up of damaged organelles and dysfunctional proteins has been linked with various age-related conditions. (1)

Autophagy is naturally activated by caloric restriction (aka fasting). When your cells sense that nutrition is scarce, it hunkers down into a protect and repair mode. Therefore, Spermidine is also considered a potential agent that mimics the action of fasting.

Spermidine benefits

As the levels of Spermidine decline with age, scientists have looked at whether boosting levels could have a positive impact on health. On that note, there have been several studies in animals that have shown some potential age-extending benefits. At this stage, it’s important to mention that these benefits have not been proven in humans:

Stimulates autophagy:

Spermidine’s ability to induce autophagy is by far the most active area of interest. non-functioning “cellular debris” fuels inflammation and DNA damage which accelerates aging. For example, mice given spermidine were shown to live longer and scientists attribute this to increased levels of autophagy which extends cellular lifespan. (2)

Heart health:

Scientists have shown that spermidine supplementation improved heart function in older mice and extended lifespan. Furthermore, they also noticed that Spermidine reduced blood pressure and improved heart cell elasticity. (3)

Liver health:

Another group of scientists found that giving Spermidine to mice improved liver function in mice by reducing inflammation and fibrosis. The researchers estimated that Spermidine supplementation could extend the lifespan of mice by 25%. (4)

Brain health:

Spermidine supplements for cognitive health is an area that’s most researched in humans. At the time of writing, there are several studies looking at whether Spermidine supplements improve memory and executive functioning in older adults.

Results so far have been conflicting with some reporting that supplementation improves cognitive health and others saying it makes no difference. (4)(5)

It’s important to reiterate that the majority of research has been carried out in animals and human trials have been inconclusive. A lot more research needs to be done before any conclusions can be drawn on the benefits of spermidine supplements.

Can Spermidine reverse aging?

The process of aging is complex and involves myriad different pathways. To better understand the process, scientists think about this in terms of the “hallmarks of aging”.

There’s a lot of debate around this, but scientists largely agree that there are around 12 different hallmarks of aging. These include things like gene instability, telomere shortening, epigenetic alterations, and mitochondrial dysfunction for example. (6)

As more research is published, the hope is that Spermidine could potentially have an impact on one or two of the hallmarks of aging which are linked to autophagy.

Therefore, Spermidine on its own will not be able to slow down or reverse aging. Even if it’s proven to support cellular autophagy in the future, this is only one of many factors that contribute to the overall mechanism of aging.

What is the richest source of spermidine?

The richest source of Spermidine is cereals, legumes, and soy derivates. (7)

That’s why all the natural spermidine supplements on the market use a source such as wheat germ.

But it’s important to note that the amount of Spermidine in food sources is a tiny fraction of that in supplements. For example, Wheat germ and soybeans contain 2,437 and 1,425 nmol/g of Spermidine respectively. That number is in nanomoles!

So it would mean you’d need to consume a kilo of soybeans (obviously not realistic), to come close to the dose you’ll obtain from supplements.

Is natural Spermidine better than Synthetic Spermidine?

One of the first things you need to decide before you buy a Spermidine supplement is whether you want a natural or synthetic source.

Natural Spermidine is most commonly found in the form of wheat germ extract. You may also come across other sources such as rice germ and buckwheat extract. These food sources naturally contain the highest amount of Spermidine. These extracts will also contain Putrescine and Spermine which are the two other polyamines.

Synthetic Spermidine is made in a lab and called Spermidine Trihydrochloride. Supplements containing synthetic Spermidine will not contain any other polyamines.

It’s not known whether natural Spermidine is better or worse than the synthetic form. There are no studies that directly compare them. Therefore, it all comes down to personal preference when choosing which form to go for.

How much Spermidine per day is recommended?

Spermidine is an ingredient that does not have a recommended daily required intake like vitamins and minerals. In other words, there is no official recommended daily requirement for Spermidine.

The Spermidine supplements on the market often contain a dose that’s slightly higher than that used in research studies (1-5mg).

The human studies so far have not yielded great results from using doses closer to 1mg and therefore, in the future, it may be that higher doses are required to achieve any benefits. With that said, this is just speculation and we won’t know what the ideal dose will be for some time.

Is it best to take Spermidine supplements with or without food?

Studies show that Spermidine is rapidly absorbed from the gut with or without food. (8)

This will come as a relief to many people, especially as many supplements are poorly absorbed from the gut.

On this note, there are many brands that sell Spermidine in liposomal format to enhance absorption. But this is unlikely to be necessary given the excellent absorption.

Spermidine supplement side effects

The side of effect profile of Spermidine supplements is generally very low. The natural Spermidine options are sourced from grains that most of us consume every day.

The main issue is that people with celiac disease should avoid wheat germ-based supplements because they will contain small amounts of gluten.

Side effects are much more common with respect to the excipients used in supplements. These are the ingredients such as magnesium stearate and silicon dioxide which are added during the manufacturing process to avoid damage to the machinery. Nowadays, the best spermidine supplements will use alternatives such as rice flour to get around this issue.

With all that said, everyone is different and side effects are always possible, regardless of the fact that Spermidine supplements are usually well-tolerated. That’s why it’s important to speak to your doctor before you start any new dietary supplement. This is particularly important if you have any other medical conditions or are taking any regular medications.

Spermidine FAQ’s

Is liposomal spermidine better?

There are some brands that sell spermidine in liposomal format with a claim of improved absorption. However, it’s unlikely that liposomal spermidine is any better than powder Spermidine. That’s because several studies have shown that Spermidine is excellently absorbed from the gut.

Liposomal supplements are great for insoluble and poorly-absorbed ingredients. However, nutrients that are easily absorbed do not need to be liposomal.

Liposomal supplements are often way more expensive and this added investment may not be worthwhile when it comes to Spermidine.

When is the best time to take Spermidine supplements?

Spermidine can be taken any time of day that suits your schedule. Given that Spermidine is present in small amounts in most of the food we consume on a daily basis, it’s unlikely that it makes a difference what time of day you take it.

How can I increase my spermidine levels naturally?

Eating more grains, soya, nuts, and mushrooms can help boost levels. However, it will be difficult to increase Spermidine levels naturally through your diet when compared to taking supplements. Most food sources contain very small amounts of Spermidine.

How much Spermidine is in wheat germ?

Wheat germ is one of the best sources of Spermidine and contains 243 mg per kilogram.

That’s why most Spermidine brands use wheat germ as their source. Additionally, the best spermidine supplements will ensure that the dose is standardized to 1%.

It seems like a small number, but it’s the highest available purity available on the market. Standardized ingredients guarantee you get the dose that’s claimed on the bottle.

Does spermidine really work?

With all this hype around Spermidine’s potential benefits, you may be wondering how much of an impact it really has.

In truth, the answer to this question is, we don’t know yet.

Although there are a number of animal studies that have demonstrated spermidine’s ability to improve the hallmarks of aging and extend lifespan, it’s not proven in humans.

Human studies are scarce and some trials have shown no improvement. It’s still too early to tell and hopefully in the next few years, as more research comes out, we will know more about the ideal dosage and length of time needed to see benefits.

Can you take Spermidine every day?

Yes, Spermidine supplements are designed to be taken every day. In terms of long-term safety data, there are a handful of studies that used Spermidine continuously for up to 12 months. They did not report any serious side effects or concerns.

However, there isn’t much data available on the use of Spermidine over 12 months. (9)

Does spermidine regrow hair?

There is a lot of interest in Spermidine as a potential supplement to support hair growth. Studies in mice and humans have shown that Spermidine significantly promotes hair growth by prolonging the anagen phase (active phase of hair growth).  (10)(11)

The researchers theorize that polyamines (which include Spermidine), are critically important for rapidly growing cells like the ones found in hair follicles. And restricting Spermidine can significantly reduce hair growth.

With that said, we don’t know yet whether Spermidine is beneficial for conditions associated with hair loss. There are many different causes of hair loss which have very different underlying mechanisms.

Nevertheless, it’s an interesting avenue of research and we will know more in the years to come. Currently, Spermidine supplements are not a recommended treatment for hair loss conditions.

How long does it take for spermidine to work?

Polyamines (which include Spermidine), are rapidly absorbed from the gut.

But how long this takes to translate into health benefits in humans is not known. In animal studies, benefits are measurable within weeks to months.

As with all things health-related, there are no quick fixes. If you were to start a new diet, you wouldn’t expect to see a difference within a few days. The same applies to Spermidine supplements. Most brands recommend continuing for around 3 months before you decide whether it’s the right choice for you.

The best way to objectively check if Spermidine is working is to carry out biological age testing before you start taking it and again a few months later to see if there is a measurable improvement.

Ultimately, Spermidine works on a cellular level, and measuring biomarkers that track cellular changes is the only reliable way to measure if it’s working.

How does spermidine make you feel?

Realistically, most people won’t feel any different. Spermidine supplements are not meant to make you feel any certain way and you should be wary of brands that claim this.

There are some anecdotal reports of people feeling as if they have more energy, mental clarity, and cognitive sharpness after taking Spermdine for several months.

However, it’s important to mention that subjective differences in how people feel are not very reliable.

So you may be thinking, what’s the point of taking Spermidine if I won’t feel any different?

Well, it’s the same way you don’t expect to feel any difference if you take omega-3 or vitamin C. Supplements are designed to support a healthy lifestyle, rather than have a drastic impact on how you feel.

How much Spermidine does David Sinclair take?

Prof David Sinclair is arguably one of the best-known scientists in the longevity field. He’s mentioned in numerous videos that he takes 1mg of Spermidine in the morning.

Aside from this, he also takes a range of other things including, Resveratrol, Quercetin, Fisetin, and NMN supplements.

Does spermidine reduce wrinkles?

If you’re taking Spermidine supplements for anti-aging benefits, you may be wondering whether it can also reduce skin wrinkles.

There are a multitude of reasons why we develop wrinkles as we age. The most important one is cumulative UV radiation from the sun. Other than this, things like your diet, genetics, and pollution/smoking play a huge role as well.

Therefore, it’s unlikely that Spermidine supplements will reduce wrinkles.

Does Speridine cause weight loss?

In short, the answer is no. At the time of writing, there is no evidence to say that taking Spermidine supplements will cause weight loss.

There are some studies that have shown that Spermidine improved insulin sensitivity as well as fat and glucose metabolism in mice. They also found that Spermidine was protective against diet-induced obesity. (12)

But these are very much preliminary studies in a small number of animals. There is nowhere near enough evidence to suggest that Spermidine can support weight loss.

The best Spermidine supplement round up

That brings us to the end of our review of the best spermidine supplements. There’s no doubt that Spermidine supplements are becoming ever more popular because of the potential anti-aging properties it could possess.

There are lots of different brands on the market and they all sell slightly different versions of Spermidine which can be confusing.

The key things to bear in mind when choosing a Spermidine supplement include:

• Decide whether you want a natural or synthetic form of Spermidine.
• Aim for a Spermidine dose of 5-10mg.
• Look for brands that are manufactured in a GMP-registered facility that also carry out 3rd party testing.
• Check for unwanted artificial fillers and additives by looking at the supplement facts table.

By following this checklist, you’ll be sure to choose a top Spermidine supplement to add to your anti-aging stack.
