Allergen Note: Contains ingredients derived from shellfish.
Description +
You can't see microplastics. That doesn't mean your body isn't dealing with them anyway.
They show up in tap water, seafood, produce, even the dust in your kitchen. Most people find that out only after they've already been eating, drinking, and breathing them for years.
Each serving works right where the exposure happens, inside the digestive tract, supporting normal digestive and elimination processes as part of regular gut function.* No extreme resets, no complicated routine. Two capsules, once a day. That's it.
Every batch is sourced to meet strict purity standards and third-party tested for quality, so what's on the label is what's actually in the capsule.
You can’t avoid microplastics. You can support what happens next. That's Sifts.
Allergen warning: Contains shellfish (crab, shrimp). Not for people with shellfish allergies.

The Data Behind the Ingredients In Sifts
In a 2026 human study, daily chitosan supplementation was associated with a 26.3% decrease in measured blood microplastic concentration after 15 days, while the placebo group showed no significant change.
Cornelli et al. (2026). PMID: 42201087
In a 2025 human crossover study, chitosan was associated with fecal elimination of microplastic particles after a standardized meal.
Casella et al. (2025). PMID: 40646942
In animal models, chitosan was associated with increased elimination of ingested microplastic particles from the gastrointestinal tract.
PMID: 40268980
Chitosan is a positively charged shellfish derived dietary fiber that can interact with negatively charged microplastic particles during digestion, supporting their movement through normal digestive elimination.
What happens during digestion.
Bind
Chitosan's positive surface charge interacts with negatively charged microplastic particles in the gastrointestinal tract, supporting their interaction with the fiber matrix during digestion.*
Buffer
Prebiotic fibers – baobab and apple pectin – are included alongside chitosan to support a healthy microbiome environment and a gentle fiber matrix during daily use.*
Protect
The fiber matrix is designed to support the body's normal elimination pathways, so bound particles can leave the body through normal digestion rather than remaining in the gut.*

A positively charged dietary fiber derived from shellfish studied for its electrostatic interaction with particles in the gut.*
Baobab Fruit Extract
A prebiotic fiber included to support a balanced microbiome environment during daily use.*
Slippery Elm
A mucilaginous fiber that supports the gut barrier and digestive comfort during daily use.*
Apple Pectin
A soluble fiber associated with gut motility and normal elimination pathways.*

"Microplastics are an emerging biomarker with growing implications for human health. Sifts is scientifically formulated with natural fibers and binders that have been studied in early clinical research for their ability to bind microplastics and support their natural elimination from the body in a safe, predictable way.*"
"As someone deeply invested in biohacking and longevity medicine, finding a proactive defense against microplastic absorption is a game-changer."
"It's such an easy addition to my routine and I really appreciate having a simple, thoughtful way to support my body given how impossible microplastics are to avoid these days."
"Sifts formula is really gentle on the body. My husband has been taking it all week without the Unwanted effects of other 'eliminators'"
"This product is so innovative! I feel like it's a safety net for all the unknown microplastics i'm ingesting… no matter how careful I think i'm being. Will be purchasing again, for sure."
Frequently Asked Questions
Contact UsSifts is a daily supplement formulated to support the body's natural processes for managing microplastics in the digestive tract.* Its carefully selected ingredients, including dietary fibers, interact with particles during digestion to support normal elimination and digestive wellness.*
Awareness of microplastics and the science around them is still relatively new, but it is evolving quickly. What we do know is that microplastic particles can carry substances such as BPA, PFAS, and other persistent chemicals. Emerging research is examining how microplastics may be associated with impacts on digestive function, immune response, cardiovascular health, fertility, and neurological pathways.
Each ingredient is third-party tested for identity, purity, and safety. Sifts is free from gluten, dairy, soy, artificial fillers, and detectable plastic residues.
Yes. Sifts is formulated for daily use by most healthy adults when taken as directed on the label. It works locally in the digestive system, does not accumulate in the body, and is designed to support consistent digestive elimination.*
Every ingredient in Sifts is Generally Recognized as Safe (GRAS) for human use as designated by the FDA and supported by published research. The formula is plastic-free and intentionally designed for regular, ongoing use.
Always follow the recommended serving size. Taking more than directed does not provide additional benefit and may increase the chance of digestive discomfort.
Sifts can be a valuable supplement for anyone exposed to food, water, and air... so practically everybody!
However, Sifts should not be used by individuals with shellfish or seafood allergies, or by those who are pregnant, breastfeeding, or under 18.
Yes. Sifts can generally be taken alongside other supplements and medications. Because Sifts contains binding fibers like chitosan, we recommend taking it at least ~1 hour apart from medications and other supplements to avoid potentially interfering with their absorption. However, Sifts is designed for daily use and is intended to support your overall wellness alongside your existing routine.
If you take prescription medication, you may want to check with your healthcare provider or pharmacist for guidance specific to your medication.
No. Taking more than the labeled serving does not provide additional benefit and is not recommended.
Sifts is formulated to be taken exactly as directed on the label. Increasing the number of capsules does not increase effectiveness and may increase the likelihood of digestive discomfort. Consistency over time is more important than taking a higher amount.
Always follow the serving size listed on the product label unless advised otherwise by a qualified healthcare professional. We will continue to monitor the results from our studies and will provide updated guidance on usage if we get new insights around how to optimize the efficacy of this supplement.
Microplastics are very small plastic particles, typically defined as being less than 5 millimeters in size.
They enter the human body primarily through ingestion and inhalation. Common sources include food, drinking water, airborne dust, and contact with plastic packaging or utensils. Over time, larger plastic items break down into smaller particles, contributing to environmental and household exposure.
Exposure to microplastics is generally unintentional and widespread.
Yes. Scientific research shows that microplastics are increasingly present in the environment and everyday life.
Microplastics are tiny plastic particles that come from the breakdown of larger plastics or are intentionally manufactured at very small sizes. They have been detected in drinking water, food, household dust, and air. As global plastic production has increased over time, background exposure has risen as well.
Researchers are actively studying what long-term, low-level exposure may mean for human health. While the science is still evolving, there is broad agreement that microplastics are now widespread in the modern environment.
