Winnow: A Scientist-Founded Approach To Everyday Wellness
Research-first principles, batch-testing transparency, and a mission shaped by environmental-exposure questions.
Shop Winnow ↓Winnow’s story begins with a scientific question and a practical ambition: how can people better navigate an increasingly contaminated world? Founded in 2025, the company describes its mission as building simple, safe, science-backed tools to help people thrive.
Its approach is defined by three principles: be precise about the research, test beyond the standard, and make product decisions that reflect the mission. The company was developed by PhD scientists with backgrounds spanning molecular biology, biochemistry, and microbiology.
Winnow At A Glance
Founded in 2025.
Co-founded by Matthew Dunn, PhD, and Andrew Larsen, PhD.
A commitment to citing study authors, publication years, and model systems.
More than 200 contaminants tested per batch, with a Certificate of Analysis available for every batch, according to the company.
A product roadmap that identifies Winnow 1 as shipping and Winnow 2 as the next stage.
Science First, With Context
Winnow’s first principle is about the way evidence is communicated. When the brand cites a study, it says it names the authors, year, and model system, and avoids claims that the literature does not support.
That distinction matters. Findings from a laboratory or animal model do not automatically establish the same effects in people. Winnow’s stated emphasis on research context invites shoppers to examine what was tested, how it was tested, and what the evidence can reasonably show.
“We Don’t Make Claims The Literature Doesn’t Support.”
Winnow’s Science-First PrincipleTest Beyond The Standard
Winnow reports testing each batch for more than 200 contaminants and making a Certificate of Analysis available for every batch. This is part of its stated quality-control approach.
A batch certificate can provide information about the tests performed and their results. It should be read as a quality-testing document, not as proof that a product produces a particular health outcome. Review the certificate for the batch you are considering when comparing products.
Match The Mission
The company’s third principle connects product purpose with packaging choices. Winnow says that if a product is about reducing microplastic exposure, its packaging should reflect that commitment too.
That is a design principle, not a claim here about a specific packaging material, a plastic-free supply chain, or demonstrated removal of microplastics from the human body. Product details and relevant research should be evaluated on their own terms.
The Scientists Behind Winnow
Matthew Dunn, PhD
CEO and co-founder Matthew Dunn holds a PhD in Molecular and Cellular Biology and completed postdoctoral work in biochemistry at UC Irvine. He previously served as VP of Technology and Intellectual Property at ArkeaBio.
At Winnow, he leads company strategy, scientific direction, and product vision.
Andrew Larsen, PhD
COO and co-founder Andrew Larsen holds a PhD in Biological Design and an MSc in Biochemistry. He co-founded Dropworks, which was later acquired by Bio-Rad.
His responsibilities at Winnow include preclinical validation, supplier qualification, and next-generation formulation work.
From Winnow 1 To What Comes Next
The company’s supplied roadmap identifies Winnow 1 as shipping and Winnow 2 as up next. The second product is presented as a future development, not a current offering in this collection.
At Daily Health & Beauty, the current Winnow catalog includes Daily Probiotic Starter Pack and Daily Probiotic Refill Packs. Check each product for its ingredients, directions, options, and product-specific supporting information.
Why We Carry Winnow
We appreciate Winnow’s emphasis on making evidence understandable and batch testing visible. The scientist-led background is an important part of its story, while individual product claims still need to be judged by the evidence supporting them.
