Seed Review – A Look at This “Synbiotic” Supplement

What comes to mind when you hear “probiotics?” It seems like the word is becoming commonplace as of late. In fact, it’s probably safe to say that probiotics are somewhat of a health trend, not too far behind bulletproof coffee, turmeric, and jackfruit. With many probiotics on the market, such as Peptiva Probiotics and Hyperbiotics PRO-15 Probiotic, there are a lot of choices. 

Not too long ago, probiotics used to be limited to yogurt or kefir, kimchi, kombucha, and supplement capsules. But now, probiotics have gotten an overhaul, thanks to a whole lot of science—and that doesn’t just mean in kombucha and other beverages. Similar to FDA regulations for foods labeled “all-natural” and the like, the word “probiotic” can be slapped onto a label for something that may not even contain any beneficial bacteria at all. 

This is where serious probiotics come into the picture in the form of a company simply called Seed. Seed’s business model and product offering are simple and straightforward, and they take their research seriously. Let’s look at what Seed is about and why their products are different.

About Seed

Seed is all about the science of bacteria. Too many of us are still programmed to think that all bacteria are bad, thanks to the over sanitization of our society. As a matter of fact, Seed points out that fewer than 100 species of bacteria out of the trillions that exist are actually harmful to humans. That means there are a whole lot that aren’t! 

If you’re wondering where Seed gets its name, it’s from the process of inheriting your microbiome from your mother, which is called “seeding.” Now, we’re going to try to leave the bulk of the science to the Seed experts, but basically, the microbiome is the foundational bacteria system in your body. Most of them are in your gut, which is why gut health is so important—and there are 38 trillion of them in your body total. That’s all the more reason Seed takes its products seriously. 

Seed Ingredients

First of all, Seed offers exactly two products: a supplement for men and a supplement for women. That makes things super simple. The primary ingredient difference from men’s to women’s supplements is the addition of bacterial strains that increase folate production in women, which is a necessary element for female fertility. The Seed formulation for men includes two strains that target muscle recovery after workouts, which makes it slightly different; however, the company states that both formulas are ultimately safe for anyone to take. 

That being said, we can now focus on the ingredients that are the same in both products. The majority of the ingredient list contains long names of bacteria that start with “bifido-” or “lacto-,” and that’s where the science takes over. No need to list all the strains of beneficial bacteria included, but they do fall into four accessible categories:

  • Digestive, immunity, and antioxidant probiotics
  • Cardiovascular probiotics
  • Dermatological probiotics
  • Microbiota-Accessible Prebiotics®

Those are fairly self-explanatory with the exception of the last one. The Microbiota-Accessible Prebiotic® blend (registered to Seed, so it is exclusive) contains a plant-based prebiotic mix of pomegranate, mushroom, and pine bark, which are all powerful antioxidants and immune boosters. This blend is unique not only because it’s patented by Seed, it’s also a new class of prebiotics that’s different from the usual dietary fibers typically categorized as prebiotics.  

When it comes to ingredients Seed doesn’t have, that’s equally important. The capsules are vegan, non-GMO, and free from allergens, gluten, preservatives, meat, corn, soy, dairy, fillers, binders, and excipients. 

A really cool feature of Seed’s capsules is that they’re “2-in-1 nested capsules.” The outer capsule contains the prebiotics, the nutrients that feed the microbiota to pave the way for the probiotics and induce their growth. Seems like those are pretty necessary for the probiotics to work, and that’s where the pomegranate, pine bark, and mushroom extracts come in. Algae is included to help protect the bacteria from external contaminants (oxygen, moisture, etc.) as well as stomach acid—that way they’re intact when delivered to the digestive tract. 

The inner capsule contains all the probiotics, 24 strains out of the trillions that potentially help our bodies. Sounds like Seed has devised the ideal delivery system, with the prebiotics digesting first and the probiotics later—all in one capsule! 

A list of “other ingredients” reveals only a few: the actual capsules themselves, made up of safe and vegan ingredients that hold them together; organic glycerin; water; rice fiber and extract; and the nutrient choline. Looks like every component of Seed’s supplements has a purpose and is highly researched to be delivered in the most beneficial way to the body. 

Seed Benefits

The benefits of Seed’s ingredients have already been touched on by default, but it’s worth mentioning that the components benefit the entire body well beyond just the gut. It’s becoming a well-known fact that the immune system begins in the gut and affects every area of the body, and the Seed company maintains that their supplement includes strains for every system. The bacteria in Seed supplements boost the gut barrier, digestive health, skin and heart health, immune system health, and metabolism at the cellular level. The result is that the whole-body health is improved from the inside out.


With Seed’s extensive development, research, and educational teams, including a scientific advisory board, you can bet that their products have been studied in depth. In fact, the bacterial strains used have been tested in over 23 studies and are verified free of all classes of allergen. Seed’s website states that their board includes doctors and scientists who specialize in genomics, immunology, gastroenterology, metabolomics, microbiome science, nutrition, and clinical research. With all the experts involved, you know that Seed not only is committed to producing a quality supplement but also testing it to ensure that it stays that way. 

In addition to Seed’s whole-genome testing and rigorous studies, the supplements go through more than 50 quality assurance checkpoints to maintain product purity for both the US and the UK standards. The products are tested before they’re finalized and again after manufacture.

Side Effects

As with anything that’s ingested, it’s best to know in advance if there are any side effects. With Seed supplements, the company warns that your body may experience a slight adjustment period as you take the supplement, but it shouldn’t last more than five days. The effects you may feel are abdominal, such as discomfort, nausea, tightness, or stool changes as your body adapts to the prebiotics and probiotics absorbing into your system. Seed recommends starting out with only one capsule daily for the first three days or so to minimize adjustment symptoms. After that, your body will most likely process the capsules better and you’ll see a noticeable difference. 

Where to Buy Seed Synbiotics

A 30-day supply of both the men’s and women’s supplements comes out to $49.99 per month with a subscription on their website. It seems that a subscription is the only option on their site—and that their site is the only place to purchase it currently. (It’s listed on Amazon as unavailable.) Evidently, Seed has a pretty exclusive product. To their credit, though, they have a really beautiful website to look at while you shop, subscribe, and learn all about the science of bacteria.

Overall, Seed’s supplements are the highest of quality, backed by extensive research and science, and more than likely worth every penny. Seed has gone far beyond a simple probiotic supplement to provide the best strains of beneficial bacteria, made absorbable by high-quality prebiotics. If you’re willing to subscribe at $50 monthly, Seed has made it easy to get and stay healthy with supplements delivered to your door. Their slogan says it all: “We got your back.”
