Winnow’s 2-in-1 proprietary probiotic blend binds microplastics in the gut while also providing the benefits of a traditional probiotic supplement.

Probiotics have been shown to:

  • Improve gut and microbiome health
  • Improve immune function
  • Decrease inflammation of the gut (IBD, ulcerative colitis, and pouchitis) 
  • Improve mental and hormonal health
  • Mitigate toxins from BPA, DEHP, pesticides, phthalates, and certain heavy metals
  • Support metabolic and liver functions

Microplastic exposure is associated with:

  • Gut barrier damage 
  • Microbiome dysbiosis 
  • Inflammation 
  • Hormonal disruption 
  • Reproductive concerns 
  • Immune system suppression 

Winnow works in a three step process to support your health in a world full of microplastic pollutants.

  1. BIND: Winnow’s probiotic bacteria bind to microplastics in the gut
  2. ELIMINATE: Once bound, microplastics can be transported through the intestines by probiotics to be eliminated naturally as waste
  3. RESTORE: With microplastics removed and your microbiome flourishing, your digestive system can do what it does best—break down food, absorb nutrients, and improve overall health

Each serving (2 capsules) contains 40 billion CFUs (colony-forming units) of natural probiotic bacteria and pre-biotic fiber, in an acid-resistant capsule for effective delivery to the gut. All ingredients are recognized as safe by the FDA.

Winnow is made in this USA in a CGMP facility with GMO-free ingredients. It is dairy free, gluten free, and vegan.

Winnow FAQs

Winnow is a 2-pill per day probiotic supplement with a patent-pending probiotic blend shown to bind microplastics in the laboratory. Winnow’s microplastic binding probiotics are complemented with additional probiotics that support a balanced gut microbiome, helping reinforce digestive health and resilience in the face of modern environmental exposures.

Absolutely. Every probiotic strain in Winnow is Generally Recognized as Safe (GRAS) for human use and has a long history of safe consumption.

No…and yes. Winnow contains a high CFU (colony forming units) dosage of the most researched, tested, and proven probiotic strains on the market which support overall digestive health. And, Winnow does something no other probiotic does. It includes a proprietary, patent-pending blend of probiotics selected for their unique abilities to bind microplastics in gut-simulated lab tests.

Our team of experts, PhDs, and advisors have decades of collective experience in microbiological engineering, gut health, and microplastics expertise to help create the most effective probiotic supplement available today.

No! Winnow is plastic-free from the capsule to the package.

Loaded question. Microplastics awareness and research is still relatively new and evolving quickly. No one knows definitively the health risks they pose. But, where there’s smoke, there’s often fire. Microplastics contain, BPA, PFAS and other harmful “forever” chemicals. Studies suggest potential respiratory, digestive, reproductive, cardiovascular, immune system, and brain health related risks.

We’ve demonstrated binding by Winnow probiotics to five different plastic types: polyethylene terepthalate (PET; commonly found in water bottles and food packaging, polyethylene (PE; plastic bags, films, and containers), polypropylene (PP; food containers, straws, and bottle caps), polyvinyl chloride (PVC; pipes, flooring, medical supplies), and polystyrene (PS; foam cups, packaging, disposable cutlery).
