The Claim

In a simulated human colon model using fecal inoculum from three healthy donors, NatureKnit™ caused a slower and more sustained decrease in pH and a more sustained increase in gas pressure over 48 hours compared to inulin and psyllium.

How it works
1 study reviewed
In plain English

When tested in a lab model of the human colon using gut bacteria from healthy people, NatureKnit™ produced a slower and more gradual drop in acidity and rise in gas pressure over 48 hours than inulin and psyllium.

See the scientific wording

In a simulated human colon model using fecal inoculum from three healthy donors, NatureKnit™ induced a slower and more sustained decrease in pH and increase in gas pressure over 48 hours compared to the rapid changes seen with inulin and psyllium, suggesting a more gradual fermentation profile.

Why this might work

NatureKnit™ contains a mix of different plant fibers and natural compounds bound to them that bacteria in the colon break down slowly. This slow breakdown means acids and gases are released steadily over time instead of all at once, which keeps the colon environment changing gently. The variety of fibers feeds many different types of bacteria, helping them grow and work together to keep fermentation going longer without sudden spikes.

  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

    This study found that NatureKnit™, a fiber blend from fruits and vegetables, makes gut bacteria work more slowly and steadily than pure fibers like inulin or psyllium, causing a gentler release of gases and acids — which might mean less bloating or discomfort.
