Can you remove microplastics from your body?
Microplastics are unavoidable
Microplastics are in your water, food and air. By the time these particles reach your gut, the exposure has already happened. The early health data around this is surprising.
Microplastics have been detected in blood, stool, placenta, and arteries.
Studies associate microplastics with cardiovascular, reproductive, metabolic, and neurological health markers, though causation remains a question.*
Research suggests microplastics may affect oxidative stress, immune and hormone signaling, gut function, and the microbiome.*
How Removal Works
Sifts contains dietary fibers, including Chitosan, which carries a positive charge. Microplastics carry a negative charge. And opposites attract.
In your gut, Sifts binds to microplastics and helps your body eliminate them naturally.*
Simple. Evidence-backed. Effective.
| Study type | What the study reported |
|---|---|
| 2025 Human Study | In an ingredient-level human study of chitosan, researchers reported 47% higher microplastic counts in stool after a standardized meal.†† |
| 2026 Human Study | In an emerging 15-day human pilot study of chitosan, researchers reported a 26.3% reduction in measured circulating microplastic concentration. Sifts is formulated with chitosan as its core digestive-support ingredient.†† |
| 2026 Lab Study | In lab testing, the Sifts formula reduced microplastic gut permeability of 50 nanometer particles by up to 42%.* |
| 2025 Animal Study | In a preclinical rat study, chitosan-fed rats showed 39.6% fecal excretion of ingested polyethylene microplastics within 24 hours, versus 14.8% in controls.†† |

What to expect with daily use
Day 1
Sifts is designed to start to begin in the gut – research shows it's ingredients can start working within 24 hours.††
Days 1 - 7
Many people report smoother digestion, more regularity, and other benefits like impacts on mood, energy and sleep, though individual experiences vary.*
Day 15+
In one ingredient level pilot-study on Sifts main ingredients, chitosan, researchers reported lower measured circulating microplastic concentration levels in blood after 15 days.††
Month 2+
Some researchers estimate that circulating microplastics remain in the bloodstream for ~2 months on average, so by the 60-day mark, you will have built a consistent daily routine through a full cycle.*
Answering your questions
Is this safe for daily use?
Yes. Sifts is made with food-grade ingredients selected for daily use and a strong safety profile. Our ingredients are used in forms and amounts consistent with GRAS standards, meaning they are generally recognized as safe under their intended use. If you have a shellfish allergy, Sifts is not for you as chitosan is derived from crustacean shells.
Will I feel it?
Everyone’s experience is different! Experiences will vary, but in the first week, many people notice more digestive regularity. However, the main mechanism is not something you necessarily feel directly. Just as microplastic exposure is often invisible, supporting your body’s ability to handle that exposure may also happen quietly in the background.
Are these Sifts studies?
Some of the studies mentioned were done on the finished Sifts formula and other studies were done on the individual ingredients in Sifts. Together, these present a compelling level of support for the mechanism behind Sifts.
