Thank you for the thoughtful feedback. Many people first notice familiar probiotic benefits like improved digestion or regularity, since Winnow is first and foremost a high quality daily probiotic designed to support gut balance. Where Winnow is different is why it’s formulated the way it is. Preclinical studies show that certain probiotic strains can bind micro and nanoplastics in lab and animal models, and related research suggests that microplastic exposure can reduce beneficial gut bacteria. Winnow is intentionally formulated with strains from the families most consistently affected, including those shown to bind micro and nanoplastics.

Thank you for sharing your experience. Based on the timing and repeatability you described, this does sound consistent with sensitivity to the prebiotic fiber in the formula, especially for people eating very low-fiber or carnivore diets. In those cases, even modest amounts of resistant starch can cause loose stools. We don’t recommend pushing through symptoms, and for some people this product simply won’t be the right fit right now. We’ll also follow up by email to continue the conversation and make this right. We appreciate you giving it a thoughtful try and listening to your body.
