The research is alarming
Scientists have confirmed microplastics in human blood, breast milk, lung tissue, and the placenta. Bottled water contains hundreds of thousands of microplastic particles per liter. You are inhaling them, eating them, and drinking them — every day, without knowing it. The wellness industry has been silent.
The science
Researchers have found microplastics and nanoplastics in human blood, lungs, stool, placenta, breast milk, semen, testes, and arterial plaque. While the full health impact is still being studied, emerging evidence links microplastic exposure to inflammation, oxidative stress, reproductive concerns, respiratory effects, digestive effects, and cardiovascular risk markers.
Chitosan research is newer. Early studies suggest chitosan may bind microplastics in the gastrointestinal tract and increase fecal excretion, but larger human trials are still needed.
Discovery and quantification of plastic particle pollution in human blood
This pioneering study detected plastic particles in human blood, showing that microplastics can become bioavailable and circulate in the bloodstream.
Detection of microplastics in human lung tissue using μFTIR spectroscopy
Researchers detected microplastics in human lung tissue samples, supporting inhalation as a potential exposure route.
Detection of Various Microplastics in Human Stool
Microplastics were detected in human stool samples, showing that people ingest and excrete plastic particles.
Plasticenta: First evidence of microplastics in human placenta
This study reported microplastic fragments in human placenta samples, raising questions about fetal exposure.
Quantitation and identification of microplastics in human placental specimens
Researchers reported microplastics in all 62 placenta samples tested, with polyethylene being the most common polymer.
Raman Microspectroscopy Detection of Microplastics in Human Breastmilk
Microplastics were detected in 26 of 34 breast milk samples, showing another possible exposure pathway.
Microplastic presence in testis and association with reproductive outcomes
Microplastics were detected in human testes. The findings raise reproductive-health questions, but causation has not been proven.
Prevalence and implications of microplastic contaminants in human semen
This study found microplastic contamination in semen from individuals without occupational exposure.
Detection of microplastics in human tissues and organs
This review summarizes evidence of microplastic detection across multiple human organ systems and biological samples.
Effects of Microplastic Exposure on Human Health
This systematic review concluded that microplastics are suspected to harm human reproductive, digestive, and respiratory health, emphasizing need for more research.
Microplastics and Nanoplastics in Atheromas and Cardiovascular Events
Patients with microplastics in plaque had higher risk of cardiovascular events. This is an association, not proof of causation.
Microplastics in drinking-water
WHO reviewed microplastics in drinking water and emphasized need for better data, standardized methods, and more research on health effects.
Ingesting chitosan can promote excretion of microplastics
In rats, chitosan appeared to bind polyethylene microplastics in the gastrointestinal tract and increased fecal excretion compared with controls.
Chitosan's Ability to Enhance Microplastic Excretion in Humans
A small human pilot study tested whether chitosan could increase fecal excretion of microplastics after a standardized meal.
Reduction in Circulating Microplastics Following Chitosan Treatment
A small pilot-controlled study reported reduced circulating microplastic counts after chitosan treatment. This is promising but preliminary and needs larger trials.
GLASRA is being built in step with the evidence. Join the waitlist to follow the science and be first when we launch.
Join the WaitlistThe studies above are provided for education and transparency. Microplastic health research is still developing, and chitosan-related findings should be considered early-stage. This section is for educational purposes only and does not provide medical advice.
First product
Our first product in development is a chitosan fiber gummy designed to support digestive regularity and plastic-conscious wellness. The goal is simple: a daily product built around credible ingredients, better packaging decisions, and transparent testing.
A fiber-like ingredient derived from chitin, currently in formulation research.
Formulated to support everyday digestive regularity.
Independent testing is part of the launch plan, not an afterthought.
From packaging to formulation, every decision weighs plastic impact.
