They Found the Best Way to Detox Microplastics – And It’s Shockingly Simple

DeLauer positions the gut as the primary gateway for microplastic entry, citing studies that smaller particles absorb easier. He acknowledges that stool can contain microplastics, so if fewer enter the bloodstream, more may end up in stool. The glutamine dose (every other day) is his empirical suggestion; he doesn't provide a study to back it but frames it as a practical measure. He also emphasizes that gut inflammation, often caused by emulsifiers like polyorbates, can further compromise the barrier, so this protocol is part of a larger gut‑centric strategy.

DeLauer singles out polyorbates as a major avoidable trigger of gut inflammation. He says that inflammation starting in the gut can cascade into systemic issues: inflammatory responses leading to immune activation and chronic low‑grade inflammation. While not the only emulsifier, polyorbates are particularly egregious because of their documented effect on mucosal barriers. He argues that just by removing them, one can significantly reduce one source of gut damage, indirectly helping microplastic clearance by preserving barrier function.

DeLauer presents this as the most promising specific intervention backed by early research on stool microplastics. He notes that bile acids naturally handle fat‑soluble toxins, and he extrapolates that nanoplastics, being capable of crossing membranes, could also be sequestered. The protocol is simple: any soluble fiber source (chia, flax, oats, etc.) plus water. He does not advocate for isolated bile acid sequestrants because food‑based fiber also feeds the microbiome and adds polyphenols.

DeLauer shifts the conversation away from fiber quantity to nutrient quality, arguing that the postbiotic effect of polyphenols may be more relevant for gut barrier integrity than sheer roughage. He ties this to the inflammation microplastics cause: even if particles get inside, a robust antioxidant defense can blunt their negative effects. Bright‑colored fruits and their extracts are his suggested sources, and he mentions that products like urolithin A (from his sponsor) are examples of postbiotics derived from polyphenols.

DeLauer emphasizes hydration as the simple, shockingly easy step that makes the other gut protocols work. Without enough water, soluble fiber can paradoxically cause constipation, and bile acid sequestration might be less effective. He repeatedly ties hydration to transit time, not just for general health but explicitly for flushing microplastics.

DeLauer lists stress reduction and not over‑exercising alongside dietary measures as real, actionable steps. He does not dive deep but implies that people often overlook lifestyle factors that directly impact gut permeability. The connection to microplastics is indirect: a healthier gut barrier reduces systemic absorption, so anything that weakens the barrier is counterproductive to the overall detox strategy.

DeLauer points to a study in Total Environment showing every participant had microplastics in their stool, and another in International Journal of Pharmaceutics confirming that smaller particles are easier to absorb through the intestinal tract. This dual evidence suggests that while absorption is inevitable, excretion via stool is possible. He therefore shifts the focus from impossible‑to‑avoid exposure to maximizing what the body can eliminate through the gut. The overarching claim is not that all microplastics can be flushed out, but that reducing absorption and enhancing fecal excretion is the most promising route given current science.

DeLauer explains that bile acids normally aid fat digestion, but they also bind fat‑soluble toxins and now, by extension, microplastics. Consuming soluble fiber (chia, flax) increases bile acid synthesis and flow, and the fiber itself binds to bile acids, facilitating their excretion. This process, combined with hydration, helps ‘flush’ the bound particles out. He frames this as a full‑circle gut health strategy: protect the gut lining so fewer particles enter, and use bile acid sequestration to clear those already in the gut. He is careful to note this is early evidence and he cannot claim it removes microplastics from organs, only that it may reduce absorption and increase fecal elimination.

DeLauer acknowledges that glutamine has attracted concerns in some circles, yet he asserts its importance for gut barrier integrity. The every‑other‑day dosing is meant to support the intestinal lining without overdoing it. He links this directly to microplastics: a tighter gut barrier means fewer small particles leak into the bloodstream. Combined with collagen and bone broth, this trifecta is his primary gut‑tightening protocol. He does not claim it works perfectly but positions it as one of the few actionable steps based on how microplastics enter the body.
