Let's do something about that.
However they get there, the route in is the same: through the gut, every meal, every day. There is one point where they can be intercepted before absorption. Somatic Labs built DDM1 to work there.

University of New Mexico researchers analysed 52 postmortem brain samples. Brain tissue carried 7–30× more microplastic than liver or kidney — roughly a plastic spoon's worth in the average brain. Concentrations rose 50% between 2016 and 2024. Samples from people with a dementia diagnosis held 3–5× more again.

The microplastics reaching brain tissue are showing up everywhere else too.

The Answer · DDM1
Microplastics enter the body through the gut — it's where absorption happens, and the only place you can intercept them. DDM1 is a once-daily powder formulated with fibers and plant polysaccharides chosen for their studied ability to bind particles like microplastics. It's designed to work in the gut — the idea being that bound particles pass through with the fiber rather than crossing into the body. Not a cleanse. Not a nootropic. A daily layer that works at the entry point — before any of it gets further.

What's inside DDM1
DDM1 combines plant-derived fibers with a lactic acid probiotic from fermented foods — each chosen for a specific functional role in the binding and elimination mechanism.
Five intentional ingredients. Nothing else — no fillers, no artificial additives, no unnecessary extras.
Final ingredient list and amounts confirmed at manufacturing. We'll always show you exactly what's inside.
When psyllium contacts water in the gut, it swells into a viscous gel that physically traps particles — including microplastics and PFAS-bound bile — before they can reach the gut lining. It's one of the most studied gel-forming fibers in human nutrition.
Certain lactic acid bacteria carry cell-wall surface groups that grab onto (adsorb) microplastic particles in the gut, forming a complex that leaves the body through normal bowel transit. This is physical adhesion, not digestion — the bacteria don't break plastic down, they hold onto it. This ability is highly strain-specific: in one screen of 784 strains, the large majority showed little useful binding. The strains that perform best come from fermented vegetables, where tolerance for acid and salt appears to carry over into surviving stomach acid and bile. DDM1 uses a lactic acid probiotic derived from fermented foods, selected against those same criteria.
Okra's mucilage — its natural gel-like fiber — carries surface chemistry (hydroxyl and carboxyl groups) that act as binding sites for microplastic particles. In water-treatment research, okra extract physically adsorbed — that is, particles stuck to its surface — and trapped microplastics, pulling them together into clumps. We selected these polysaccharides for that binding chemistry, with the aim of capturing particles in the gut.
Fenugreek's galactomannan polysaccharides complement the okra binding matrix. In that same water-treatment research, fenugreek extract showed the highest microplastic removal of any plant polysaccharide tested — which is why we paired it with okra in the fiber matrix. It also contributes to the viscosity of the gel formed in the gut.
Partially hydrolyzed guar gum (PHGG) and acacia fiber are added for two reasons: they improve the texture and mixability of the powder — making the daily habit easier to sustain — and they support a healthy gut microbiome environment, reinforcing the gut barrier that the binding mechanism is designed to protect.
What the research shows
Finally something that addresses exposure before it becomes a problem. Every other product is cleaning up after the fact — this is the first one thinking upstream.
I've been recommending patients reduce environmental exposure for years with very few practical tools. A once-daily gut-level intervention is exactly what I've been waiting for.
