The biggest dietary sources of microplastics are seafood, salt, bottled and tap water, and foods packaged or heated in plastic — and the highest-impact way to cut exposure is to store and heat food in glass or steel instead of plastic. No food is “microplastic-free,” but a few simple swaps meaningfully reduce how much you take in.
This page is educational, not medical advice. Reducing exposure is a sensible precaution; no supplement removes microplastics already in your body. If you have a specific health concern, talk to your clinician. These statements have not been evaluated by the FDA.

​
Which foods carry the most microplastics?

Microplastics have been measured across many foods, but a few stand out:
  • Seafood, especially shellfish like mussels, oysters, and clams — because you eat the whole animal, including the digestive tract where particles collect.
  • Salt, particularly sea salt, which concentrates particles from ocean water.
  • Bottled water, which a 2024 study found can carry hundreds of thousands of nanoplastic particles per liter.
  • Foods packaged, stored, or heated in plastic — takeout containers, plastic-wrapped items, and anything microwaved in plastic.
  • Highly processed foods, which pass through more plastic equipment and packaging on the way to you.

​
How do microplastics get into food?

Two main routes: environmental (plastic pollution breaking down in oceans and soil, then entering the food chain) and contact (particles shedding directly from packaging, bottles, cutting boards, and containers — especially with heat, acidity, or wear). Contact sources are the ones you can most easily control.

​
What actually helps

  • Store and reheat in glass or steel, not plastic. Heat drives more particles into food and drink.
  • Skip single-use plastic water bottles — refill glass or stainless steel. See reduce microplastics in drinking water.
  • Cook more whole foods and cut back on heavily packaged, processed items.
  • Filter tap water with a certified particulate filter.
  • Don’t microwave in plastic, and replace scratched plastic containers and worn cutting boards.
  • Eat fiber-rich foods, which support your body’s normal elimination.

​
Where does a supplement fit?

Exposure reduction comes first — no product replaces it. Your body also has its own natural elimination pathways, and gut-level binders like clinoptilolite zeolite are used to support (not replace) those pathways as part of a daily routine. Plastiq Off pairs micronized zeolite with active B12 for gentle daily support alongside smarter food and water habits. It does not remove microplastics from your body or your food.
Be skeptical of any product claiming to “flush” or “remove” microplastics from your body — those claims aren’t supported. If you’re worried about a health effect from exposure, see a clinician.

​
The bottom line

Cut plastic contact — store and heat food in glass or steel, skip plastic water bottles, and eat more whole foods and fiber. Those habits do the heavy lifting. A gut-level binder can be part of a daily routine, but reducing exposure is the priority.
