Approach 1, macro science, in palette D, bold color field.

Extreme macro photograph of a single translucent, gel-like chitosan flake with a fibrous, glassy texture. Tiny colorful microplastic fragments and thin fibers are caught in its web, as if trapped in a net. The flake rests at the center of the frame against a saturated, evenly lit tomato-red backdrop, with a shallow depth of field that blurs the background fragments into soft bokeh. The camera sits at a slight top-down angle, about 30 degrees off the surface. Soft diffused studio light comes from the upper left and creates crisp specular highlights along the gel's edges. One tiny electric green fragment among the plastics adds a subtle accent. The mood is clean, curious and cautiously hopeful, with a microscopy-like realism and no text.

Microplastics in Your Blood? Chitosan Cut Levels 26% in 15 Days

BY NOVA CHEN · Oct 20, 2026

Every participant in a new pilot study had microplastics in their blood, and that's before anyone took a supplement. Then 11 people took 0.8 g/day of crayfish-derived chitosan for 15 days and saw blood plastic levels fall 26.3%, while controls didn't budge. Earlier rat work hints chitosan may gel in the gut and carry plastics out in stool. But with only 21 participants, no health outcomes and immature measurement methods, this is a promising lead rather than a proven detox. Here's what the study found, what it can't tell us, and how to think about it sensibly.
