Kimchi is a popular fermented cabbage dish that comes from Korea, originating thousands of years ago as a method of preserving vegetables. Kimchi has been getting attention for its possible role in removing microplastics from the body.
The short answer
There's real research behind the headlines. Scientists studied a specific bacterium taken from kimchi. The findings are promising, so let's dig deeper into the science behind how it works.
What did researchers find?
In a 2026 study, scientists tested a kimchi-derived bacterium called Leuconostoc mesenteroides CBA3656 against polystyrene nanoplastics. Nanoplastics are extremely small plastic particles.
In a lab setup designed to mimic conditions in the human intestine, the bacterium bound to about 57% of the nanoplastics tested.
The researchers also studied germ-free mice. Mice given the bacterium had more than twice as much nanoplastic detected in their poop compared with mice that didn't receive it. That suggests the bacterium helped carry particles out through the digestive tract.
How could bacteria help carry plastic out?
The idea is fairly simple: certain bacteria have surfaces that tiny plastic particles can stick to.
Scientists call this adsorption. Think of particles sticking to the outside of something, like lint on a sweater.
If those bacteria and the attached particles leave through poop, that may help move plastic out of the gut. This is the process researchers explored in the kimchi study. It does not mean the bacteria dissolved the plastic.
Does eating kimchi have the same effect?
We don't know yet.
A jar of kimchi is different from a measured amount of one carefully selected bacterial strain. The bacteria present can vary, and the study doesn't tell us how much kimchi someone would need to eat or whether eating it would produce the same result.
The findings also don't show that kimchi removes plastic already stored in organs or tissues.
For now, the research gives scientists a reason to keep studying specific microbes. It doesn't give us a proven kimchi detox protocol.
Do any other probiotics work similarly?
Yes. Strains of Lactiplantibacillus plantarum (L. plantarum), the same species as the probiotic in Clear, have also been shown to bind plastic particles and help move them out of the gut.
Like the kimchi-derived bacterium, these bacteria use a process called biosorption. Their surfaces act like microscopic Velcro which allows tiny plastic particles to stick to them and travel through the digestive tract.
In one study, researchers tested 784 bacterial strains. L. plantarum DT88 was among the strongest plastic binders. When tested in mice, it helped increase plastic elimination through poop and reduced the amount left in the intestines.
These findings show that certain beneficial bacteria can help carry plastic out of the gut, giving researchers a clearer picture of how this process works. Binding varies from strain to strain, and the L. plantarum in Clear has not been tested for it.
Feeding your microbes is part of the bigger picture
Fermented foods like kimchi can bring bacteria into your diet. Fiber helps feed these beneficial bacteria already living in your gut.
Your own digestive enzymes can't fully break down fiber. Much of it reaches your colon, where gut bacteria use certain fibers as food. As they break those fibers down through fermentation, they make short-chain fatty acids (SCFAs), mainly acetate, propionate and butyrate.
These small compounds help fuel the cells lining your colon and support the gut's protective barrier. They're part of what makes feeding your gut bacteria so valuable.
How Fiber Shield feeds your gut microbes
Fiber Shield contains NatureKnit®, a blend of plant fibers that still carry their naturally bound polyphenols. Polyphenols are plant compounds with antioxidant properties.
Because these polyphenols remain attached to the fiber, they travel with it to the colon. There, gut bacteria help release and break them down.
Your microbes get access to both the fiber and its attached plant compounds. Different microbes use different resources, so a varied blend can help nourish a broader community.
We explain how this works in our article about polyphenol-bound fiber.
Fiber Shield combines this polyphenol-bound fiber with Okralin™ okra, organic prickly pear and organic beetroot to support beneficial gut bacteria, the gut lining and regularity.*
We don't yet know whether Fiber Shield feeds the specific bacterium tested in the kimchi study or improves its ability to bind plastic. Its role here is daily support for the gut environment where beneficial microbes live.
Where Clear fits
Clear supports the next part of that process. BroccoPhane® supplies sulforaphane to support pathways that help your body process certain unwanted chemicals for removal. Milk thistle provides liver and antioxidant support, while chlorella has been studied for helping carry certain environmental pollutants out through the gut.*
Together, they provide daily support for a well-fed microbiome, a healthy gut barrier and your body's natural detoxification processes.*
Common questions
How much kimchi should I eat to remove microplastics?
There is no established amount. The study tested an isolated bacterial strain rather than servings of kimchi.
Can kimchi remove microplastics from the brain or blood?
The research discussed here does not show that. It focused on binding particles in the digestive tract and their passage into stool.
Is kimchi still worth eating?
If you enjoy it and tolerate it, kimchi can have a place in your meals. You don't need to give it a plastic-removal job to enjoy it alongside dinner.
Give your gut daily support
The kimchi research is a reminder of how much our gut microbes may have to offer. Feeding and supporting them is something we can make part of everyday life.
That's why we created the WildType Plastic Defense Kit. Fiber Shield nourishes beneficial bacteria and supports the gut's protective barrier and regularity. Clear complements that work with liver, antioxidant and natural detoxification support.*
