Does microplastics exposure from teabags harm your kidneys?
The research on microplastics is still building, but early signals point toward cutting back where it is easy to do so.
What the study actually looked at
The paper behind this page is "Effects of Microplastics and Nanoplastics on the Kidneys." You can read it in Nephrol Dial Transplant (2026).
Short version: the research looked at how microplastics can affect the body. It did not directly test teabags, but microplastics is one of the things people run into when they use teabags, which is why parents ask about it.
What this means for you
If cutting back on microplastics is on your radar, the simplest move is to swap the products most likely to contain it. That is not about panic. It is about picking the easier option when a safer one exists.
One study alone will not close the case. But if you are pregnant, feeding a toddler, or just want less of this stuff around the house, steering clear of microplastics where you can is a fair call.
The bottom line
The science backs taking microplastics seriously. Picking microplastics-free options where possible is a low-effort way to cut how much of it ends up in your body.
