The Claim

In a simulated human colon model using fecal inoculum from three healthy donors, NatureKnit™ increased absolute bacterial abundance in the lumen compartment by 170% after 48 hours compared to a negative control, and this increase exceeded those observed with inulin and psyllium.

In plain English

In a lab model mimicking the human colon, a substance called NatureKnit™ caused a 170% increase in the total number of bacteria in the lumen after 48 hours, more 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 absolute bacterial abundance in the lumen compartment by 170% after 48 hours compared to a negative control, exceeding the increases seen with inulin and psyllium, suggesting a stronger stimulation of microbial growth.

Why this might work

A diverse mix of plant fibers and bound polyphenols reaches the colon untouched, where gut bacteria slowly break them apart and use the released sugars and compounds to multiply and produce acids. This steady supply of food supports more types of bacteria to grow in large numbers, especially in the far end of the colon, where other fibers run out too quickly.

  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

    A special fiber blend called NatureKnit™ made more gut bacteria grow in a lab model of the colon than common fibers like inulin or psyllium — it boosted bacteria by 170%, which was more than the others.
