Story summary

Researchers reported the first human demonstration that a dead-bacteria supplement Qi601 can bind microplastic particles.
Qi601 captured up to 92 percent of nanoplastics in fluids that mimic digestion and, when delivered as 10 mg gum powder, lowered saliva particles from 2,152 to 185.
Scientists cautioned that the trial did not prove excretion of bound particles and that ongoing exposure from food, water and air remains a source.
