A note on transparency

First, it is important to clarify what Winnow is and what it is not.

Winnow is not a drug.
It is not a detox treatment.
It is not a medical therapy.

Winnow is a probiotic supplement,
containing probiotic bacteria, prebiotic fiber, and a vegan, acid-resistant capsule.

Nothing synthetic. Nothing engineered. Nothing pharmaceutical.

Specifically, it is a carefully formulated blend of well studied probiotic strains and prebiotic fiber. Some of those strains have demonstrated the ability, in laboratory and preclinical research, to interact with and bind to microplastic particles within the intestinal environment.

This binding behavior is not synthetic, engineered, or chemical detoxification. It is a natural property of certain microbial cell surfaces that has been observed in scientific research. The strains in Winnow were selected first and foremost for their probiotic benefits, with this additional plastic binding behavior emerging as an intriguing and promising characteristic.

But there are also things the science does not yet prove.

We have never claimed that Winnow removes microplastics from the bloodstream, tissues, or organs. We have never described it as a cure, a medical therapy, or a detox treatment. Those types of claims would place a product in a very different regulatory category.

We also believe consumer protections matter. In many ways, that belief is part of why Winnow exists. Our goal is to give people tools to take back some measure of control in an increasingly polluted world. That commitment, embodied by our mantra - Good in. Bad out. - shapes how we communicate our science and how we describe the product. It also guides how we manufacture it. Every batch undergoes extensive quality assurance and quality control, including independent contaminant screening through laboratories such as Light Labs.

The science around microplastics and human health is still emerging. As a company working in this area, we take that responsibility seriously. That is why we publish our sources. Why we openly discuss uncertainty. And why we continue to support ongoing research into how environmental particles interact with the gut microbiome.

Scientific progress depends on scrutiny and investigation. Design. Build. Test. Learn. Redesign. We embrace that process.

In fact, emerging fields often face this kind of scrutiny early on. Environmental health science has seen similar moments before. The health risks of lead, tobacco smoke, airborne particulate pollution, certain pesticides, and industrial trans fats all became clear only after years of investigation, debate, and accumulating evidence.

We believe careful science, transparency, and open discussion ultimately move these fields forward.

And we will continue doing what we have done from the beginning.

Building a probiotic grounded in transparent science.
