Description +
Microplastics are increasingly present in the modern environment. Sifts is formulated with dietary fibers and botanicals that function within the digestive tract, where everyday dietary exposures naturally pass through the body.
Its ingredients are studied for their physical interactions during digestion and for supporting the body’s normal digestive and elimination processes as part of regular gut function.*
Each serving is formulated with Chitosan, a dietary fiber that has been shown to interact with particles like microplastics in the gut, supporting the body's natural elimination processes.
We source premium ingredients that meet strict purity standards and are third-party tested for quality.
Simple routine for daily wellness. Target modern exposures with modern nutrition.
Allergen warning: Contains shellfish (crab, shrimp). Not for people with shellfish allergies.

The core ingredient in Sifts, Chitosan, is linked to microplastic elimination through digestion - and lower measured microplastic levels in blood.
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.

In a 2025 human crossover study, chitosan was associated with fecal elimination of microplastic particles after a standardized meal.

In animal models, chitosan was associated with increased elimination of ingested microplastic particles from the gastrointestinal tract.

Chitosan is a positively charged 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.*

Board-certified physician, NIH-funded cardiology research, previously at the National Institutes of Health.
"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."
