The Hidden Plastic in Conventional Chewing Gum
Most people are unaware that conventional chewing gum contains synthetic plastics in its "gum base," a term that conceals a variety of petroleum-derived polymers. Historically, gum was made from chicle, a natural tree sap, but manufacturers switched to cheaper synthetic materials like polyethylene (used in plastic bags) and polyvinyl acetate (used in glue) after World War II. These plastic-based gums are not biodegradable and can persist in the environment for years, breaking down into microplastic pollutants that harm ecosystems. Recent research has confirmed that chewing these gums actively releases microplastics into the mouth, which can then be ingested.
The Rise of Natural, Plastic-Free Alternatives
In response to growing environmental and health concerns, a new wave of gum manufacturers has emerged, returning to the ancient practice of using natural, plant-based ingredients. The primary ingredient in these eco-friendly gums is often sustainably harvested chicle or other plant-based resins. These ingredients provide the same satisfying chewiness without the plastic, and they are completely biodegradable, offering a clear path to chewing without contributing to microplastic pollution.
Leading Brands of Microplastic-Free Gum
Several brands now specialize in creating plastic-free chewing gum. Here are some of the most prominent ones:
- Simply Gum: One of the pioneers in the natural gum space, Simply Gum was founded after the creator discovered plastic in conventional gum. Their gum base uses chicle from Central America, alongside other natural ingredients like candelilla wax and citric acid.
- Chewsy: This UK-based brand is known for its transparent, plant-based ingredients and 100% xylitol sweetener. Their gum base is also derived from chicle, and their packaging is entirely plastic-free and recyclable.
- Glee Gum: This brand is another long-standing leader, sourcing its chicle sustainably from Central American rainforests and ensuring fair wages for the harvesters. They offer both sugar-free and regular options.
- True Gum: Based in Copenhagen, True Gum also uses chicle from sustainably harvested sapodilla trees. It is vegan and uses plant-based sweeteners like stevia and xylitol.
- Underbrush: This brand is notable for being extremely transparent about its ingredients and even uses a specific type of nano-hydroxyapatite (nHAp) that is EU-approved for oral health benefits.
- Refresh Gum: This brand offers another plastic-free and vegan alternative, using chicle and other natural, organic ingredients.
The Importance of Reading Labels
When shopping for plastic-free gum, it's essential to scrutinize the ingredient list beyond a simple glance. Many brands use the ambiguous term "gum base" to hide synthetic plastics. Some products marketed as "natural" may still contain a conventional gum base. Look for brands that explicitly state their gum base is made from natural, plant-based sources like chicle or mastic gum.

Environmental and Health Implications
The decision to switch to a microplastic-free gum goes beyond a simple change in habit; it’s a choice with significant environmental and personal health implications. The synthetic gum base in conventional gums is a major source of microplastic pollution. When littered, it can take centuries to break down, contaminating soil and water with tiny plastic fragments that harm wildlife and enter the food chain. Natural, plant-based gums, on the other hand, are biodegradable and compostable, returning to the earth without leaving behind toxic residue. From a health perspective, while the long-term effects of ingesting microplastics are still being studied, avoiding them is a prudent step toward reducing overall exposure. Many natural gums also use healthier, plant-based sweeteners like xylitol, which can benefit dental health by reducing plaque.
Conclusion: Making a Mindful Chew
For those seeking a healthier and more sustainable chewing gum option, the answer to which gum has no microplastics is clear: look for brands that use a natural, plant-based gum base like chicle or mastic gum. While a 2025 pilot study indicated even some "natural" gums can shed microplastics, further investigation is needed, and transparency from brands is key. By choosing from reputable, transparent companies that explicitly state their gum base is plastic-free, you can enjoy a fresh, long-lasting flavor without worrying about ingesting synthetic polymers or contributing to plastic pollution. Making this small change is a powerful way to reduce your environmental footprint and support your own well-being.
