Which Chewing Gum Without Microplastics?

Chewing gum seems harmless, right? But what if every chew released hundreds of tiny plastic particles into your body? Yikes. If you're health-conscious or care about the environment, you'll want to know the truth about what's hiding in your gum—and which brands are actually safe.

Yes, most conventional chewing gums contain microplastics. Studies found that a single gram of gum can release up to 637 plastic particles into saliva during chewing. These particles originate from synthetic gum bases made with plastic polymers. However, plastic-free alternatives like Chewsy, Glee Gum, and Simply Gum offer safer, eco-conscious options.

 

If you're worried about what you're chewing, you're not alone. Let’s dig into the science and discover which brands you can trust to be plastic-free.

Does Chewing Gum Give Microplastics?

Recent studies have shown that yes, chewing gum can shed microplastics—tiny fragments of plastic less than 5mm in size—into your saliva while you chew. In fact, researchers found that a single gram of gum releases an average of 100 to 637 microplastics, depending on the brand and composition. That means every chew could expose you to hundreds or even thousands of invisible plastic particles.

Do Many Chewing Gums Contain Plastic?

Yes, most mainstream chewing gums include synthetic polymers like polyvinyl acetate or polyethylene, which are types of plastic. Some individual gum pieces—especially the larger ones—can release up to 3,000 plastic particles during chewing. That plastic doesn’t dissolve or digest, and although we spit most of it out, a portion gets ingested.

Is Chewing Gum Made of Plastic?

Technically, yes. Most commercial chewing gum is made from a base that includes synthetic rubber or plastic. The ingredient "gum base" on a label is a catch-all term for materials that often include plastics. These compounds give gum its chewy texture and long-lasting consistency, but they come at a cost to both health and environment.

What Is Gum Base Made Of?

Gum base is a proprietary mix that may include:

• ✅Polyvinyl acetate (a synthetic polymer)
• ✅Butyl rubber
• ✅Paraffin wax
• ✅Polyethylene
• ✅Talc

While these help maintain flavor and chew, they're not exactly natural or biodegradable. That’s where plastic-free gum alternatives come in.

Microplastics in Chewing Gum: What Studies Show

In a 2025 pilot study, researchers measured microplastic release during chewing and found:

• 94% of particles were released in the first 8 minutes
• A person chewing 180 pieces per year could ingest over 30,000 microplastic fragments

This makes gum one of the most unexpected sources of microplastic exposure in everyday life.

Plastic-Free Chewing Gum Brands: What to Buy

Thankfully, a few brands are fighting back with natural, biodegradable alternatives. These gums use chicle, a natural tree sap, instead of synthetic rubber or plastic. Here is one of the top brands to look out for:

• ✅True Gum - Made with chicle from the sapodilla tree, True Gum is plastic-free, palm oil-free, and uses natural flavors and plant-based sweeteners like xylitol and stevia. It is suitable for vegans and is produced in an eco-friendly factory near Copenhagen.
• ✅Chewsy - A plant-based, plastic-free gum made with a natural gum base from tree sap. It is sugar-free and sweetened with xylitol, which is beneficial for teeth.
• ✅Glee Gum - Uses chicle from the sapodilla tree and is free from artificial flavors, coloring, sweeteners, and synthetic plastics. It is available on Amazon Australia.
• ✅Simply Gum - Founded in 2014, this brand uses tree sap as a base and focuses on sustainable packaging and natural ingredients.
• ✅Suifa Gum - Biodegradable, no artificial sweeteners, vegan and sugar-free.

👉 These brands are not only better for your health, but they also don’t pollute the planet like conventional gums.

What Is Biodegradable Gum and How Does It Work?

Biodegradable gum uses natural tree resins like chicle instead of synthetic polymers. This means the gum will break down naturally over time, instead of sticking to sidewalks and lasting for decades. It’s a small swap with a huge eco-impact.

Is Gum Bad for the Environment?

Yes—most gums are not biodegradable, and discarded pieces can stick to sidewalks and walls for years. They’re often considered a form of plastic pollution, requiring costly cleanup by cities. Switching to biodegradable options is one of the simplest ways to reduce your footprint.

Final Thoughts: How to Choose the Best Plastic-Free Gum

Chewing gum shouldn't come with a side of plastic. Thankfully, you’ve got great alternatives. Brands like Chewsy, Suifa Gum, Simply Gum, True Gum, and Glee Gum prove that it’s possible to enjoy your favorite habit—without microplastics.
