Microplastics have been detected in human blood, lung, and placental tissue, but scientists don’t yet fully know what health effects — if any — they cause at everyday exposure levels. The honest summary: presence is not the same as proven harm, the research is young and evolving, and reducing exposure is a reasonable precaution rather than a response to a settled danger.
This page is educational and not medical advice. It does not claim that microplastics cause any specific disease, and no product treats microplastic exposure. If you have a health concern, talk to your clinician. These statements have not been evaluated by the FDA.

​
Have microplastics been found in the human body?

Yes. Studies in recent years have detected microplastic and nanoplastic particles in human blood and in lung and placental tissue. That tells us particles can reach the body — but detecting particles is different from showing they cause harm, which researchers are still investigating.

​
How much are we exposed to?

Estimates vary widely and remain uncertain. People take in microplastics through food, water, and air, and some widely-repeated figures (like “a credit card’s worth a week”) are contested and not well established. Because the measurements are still maturing, it’s best to treat specific numbers cautiously.

​
What are the possible concerns?

Researchers are studying whether microplastics — and the chemical additives some plastics carry, such as certain phthalates and bisphenols that can act as endocrine disruptors — could affect inflammation, hormones, or cardiovascular health. This work is ongoing and not yet conclusive for microplastics specifically, so no firm cause-and-effect claims can be made today.

​
What can you actually do?

The practical takeaways focus on reducing new exposure:
  • Choose glass or stainless steel over plastic for food and drinks.
  • Filter tap water and skip single-use plastic bottles. See reducing microplastics in drinking water.
  • Don’t microwave or heat food in plastic.
  • Eat fiber-rich whole foods and stay hydrated to support normal digestion and elimination.

Where does a detox supplement fit?

Your body already has natural elimination pathways. Gut-level binders like clinoptilolite zeolite are used to support those pathways — not to “flush” particles out, which no supplement does. Plastiq Off offers that kind of gentle daily support (zeolite + active B12) alongside the exposure-reduction habits above, which do the real heavy lifting.
