The Claim

In a simulated human colon model using fecal inoculum from three healthy donors, NatureKnit™ increased bacterial richness in the lumen compartment by 37% (from 496 to 680 observed taxa) after 48 hours compared to a negative control, with a greater effect on microbial diversity than inulin or psyllium under these conditions.

In plain English

In a lab model of the human colon using stool from three healthy people, NatureKnit™ increased the number of different bacterial species in the gut fluid by 37% after 48 hours compared to a control, and this increase was larger than what was seen with inulin or psyllium.

See the scientific wording

In a simulated human colon model using fecal inoculum from three healthy donors, NatureKnit™ significantly increased bacterial richness in the lumen compartment by 37% (from 496 to 680 observed taxa) after 48 hours compared to a negative control, suggesting a broader impact on microbial diversity than inulin or psyllium under these conditions.

Why this might work

A mix of different plant fibers and bound polyphenols reaches the colon untouched, where gut bacteria slowly break them down over time. This slow breakdown feeds many different types of bacteria throughout the entire colon, not just the front part. As more types of bacteria grow and multiply, the number of different species increases, and the overall amount of bacteria rises. The process also lowers the colon’s acidity and reduces harmful byproducts from protein breakdown, creating a better environment for diverse microbes to thrive.

  1. Study: Effects of NatureKnit™, a Blend of Fruit and Vegetable Fibers Rich in Naturally Occurring Bound Polyphenols, on the Metabolic Activity and Community Composition of the Human Gut Microbiome Using the M-SHIME® Gastrointestinal Model

    In a lab model of the human gut, a fiber blend from fruits and vegetables made more types of good bacteria grow than plain fibers like inulin or psyllium — showing it might be better at boosting gut health.
