Chewing Gum Brands Ranked for Microplastics (2026)

Last updated: May 25, 2026

The gum base label problem

When you read the ingredients list of a chewing gum, you'll see “gum base” listed — but not what's in it. The FDA permits more than 45 different ingredients under the “gum base” label (21 CFR 172.615), including:

• Polyethylene (same plastic as plastic bags)
• Polyvinyl acetate (used in white glue)
• Styrene-butadiene rubber (used in car tyres)
• Polyisobutylene (synthetic rubber)
• Butyl rubber (used in inner tubes)
• Paraffin wax (petroleum-derived)

Manufacturers don't have to disclose which combination they use, and most don't. The default assumption for any mainstream brand is that the gum base is synthetic.

The 2025 UCLA pilot study refresher

Sanjay Mohanty and Lisa Lowe at UCLA presented pilot data in March 2025 measuring microplastic release from 10 popular gum brands. Findings (recap from our dedicated chewing gum article):

• Average ~100 microplastic particles per gram of gum.
• One outlier brand released over 600 particles/gram.
• 94% of release happened in the first 8 minutes of chewing.
• Both synthetic-labelled AND natural-labelled gums released particles in similar ranges — “natural” gum base claims often aren't verified.

Major brands ranked

Where to buy chicle gum

• Whole Foods Market — usually carries Glee Gum and Simply Gum.
• Sprouts — Glee Gum and Pur.
• Amazon — all the recommended chicle brands.
• Thrive Market — Simply Gum, Glee Gum.
• Direct from brand websites — Chicza, Simply Gum, Glee Gum all sell direct, often with subscription savings.
• European pharmacies — Chicza and True Gum widely available.
• Most major US grocers — increasingly carry at least Simply Gum in the natural-foods aisle.

How to read a gum label

1. Look for “chicle” or specific tree gum. If the ingredient list says chicle, sapodilla, jelutong, or another specific tree resin — it's plant-based.
2. If it just says “gum base”, assume synthetic. The default for any mainstream brand.
3. Don't trust “natural” or “plant-based” on the front without verifying via ingredient list — the 2025 UCLA study showed claims often don't hold up.
4. Look for biodegradable certifications (TÜV OK Biodegradable for True Gum, etc.) as a proxy signal.
5. Skip gum balls and vending machine gum — almost universally synthetic with no certification.

Alternatives to gum entirely

• Xylitol mints (Spry, PUR mints, B-Fresh) — dental-positive without gum base.
• Sugar-free hard candies from natural-foods brands.
• Plain water + breath strips (organic options exist).
• Whole fennel seeds or cardamom pods — traditional breath fresheners in many cultures.
