The mechanism, the ingredients, and the published studies.
rmvd was made to work with normal digestion rather than against it: binding particles first, keeping things moving second, then supporting the gut lining & microbiome for the long haul. rmvd was made to work with your normal digestion: binding particles first, keeping things moving second, then supporting the gut lining & microbiome for the long haul.
Chitosan, a fiber derived from crustacean shells, forms a gel in the stomach that can trap dietary microplastic particles alongside food as it's digested.
Magnesium oxide and ginger root extract support regular motility, so bound particles are carried through and cleared rather than sitting in the gut.
Sodium butyrate, zinc bisglycinate, and the LactoSpore probiotic strain support the intestinal lining and microbiome that stand between exposure and absorption.*

They are in the water you drink, the food you eat & the air you breathe.
Avoiding them completely is virtually impossible, so we built rmvd to help support your body's ability to pass them naturally - while supporting your gut lining and microbiome along the way.*

Six active ingredients, three key jobs: Bind, Move, Support.
The science is in the ingredients. Below is the published research behind each active ingredient, plus the research on exposure that explains why we built it. These are independent third-party studies on the ingredients themselves, not studies of rmvd, and not all of them used our exact doses or forms. Every reference below links to the paper itself.

In a 2025 study in the journal Foods, healthy adults took 800 mg of PCC chitosan with a meal. Researchers then measured roughly 45% more microplastic in their stool, across nine different plastic types. rmvd carries 1 g of that same chitosan, which is more than the study used.
You can read the research in full on our Science page.*
Three capsules once a day, with your largest meal.
The timing matters. Chitosan works on what is in your gut at the time, so taking it alongside the meal most likely to carry microplastics is where it does the most good.
One bottle is 90 capsules, a 30 day supply.*
Six active ingredients: 1 g chitosan, 150 mg magnesium (as magnesium oxide), 250 mg ginger root extract, micro-encapsulated sodium butyrate, 15 mg zinc (as zinc bisglycinate), and 2 billion CFU of LactoSpore (Bacillus coagulans MTCC 5856).
If you have a shellfish allergy, rmvd is not for you. The chitosan is made from crustacean shell, so the bottle carries a shellfish allergen warning.
Blended and packaged in a U.S. facility, with globally sourced ingredients.*
Yes, a few people should sit this one out or check with a doctor first.
Anyone with a shellfish allergy, since the chitosan comes from crustacean shell. Anyone who is pregnant or nursing. Anyone under 18.
And if you take prescription medication, speak to your doctor and leave a couple of hours between your medication and rmvd. A binding fiber works on whatever is in the gut at the time, including things you do want to absorb.*
Fair question in a category this new.
The main ingredient has published human research behind it, which is unusual here. The formula was built with our medical and research advisory board rather than assembled to hit a price. And it is lab tested and made in a U.S. facility before it ships.*
