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.

Sifts is formulated with ingredients that interact with microplastics during digestion, supporting their excretion through normal bowel movements.

Its formulation is intentionally focused on the digestive tract, where everyday exposures pass through the body. By interacting with certain particles during digestion, Sifts supports their normal exit. This gut-based approach complements the body's existing elimination pathways and is designed for consistent, daily use.

As scientific research on microplastics continues to advance, Sifts is positioned as a practical, gut-focused way to support the body's natural processes.*

Each ingredient is third-party tested for identity, purity, and safety. Sifts is free from gluten, dairy, soy, artificial fillers, and detectable plastic residues.

No. Sifts does not contain plastic or microplastics.

The capsules and ingredients used in Sifts are carefully selected to avoid plastic content. The formula itself is plastic-free, and the product is designed with a strong emphasis on minimizing unnecessary plastic exposure wherever possible.

If you have specific questions about materials or packaging, our support team is happy to provide additional detail!

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.

Sifts is formulated with Chitosan, a dietary fiber backed by human clinical research. In a published study of this ingredient, participants showed an association with increased natural microplastic excretion within 24 to 72 hours of ingestion.*

Additionally, preclinical and animal studies suggest that Chitosan may play a role in the excretion of ingested particles from the gastrointestinal tract.* While every body is different, consistent daily use supports ongoing clearance and gut health over time.*

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 have been detected in human blood, lungs, liver, and even the brain. Emerging research shows their presence in arteries is associated with up to 2× higher risk of heart attack or stroke, and they've also been linked to hormone disruption, fertility issues, and cognitive decline. Supporting the body's natural elimination processes is an emerging focus in environmental and metabolic health.

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.

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.
