The Claim

A proprietary blend of fruit and vegetable fibers rich in bound polyphenols (NatureKnit™), administered at 1.667 g/L in a simulated human colon model using fecal inoculum from three healthy donors, significantly increased total short-chain fatty acid production by 29.2 mM between 6 and 24 hours, surpassing the increases observed with inulin and psyllium.

How it works
1 study reviewed
In plain English

A specific fiber blend called NatureKnit™, when tested in a lab system mimicking the human colon, produced 29.2 mM more short-chain fatty acids than inulin or psyllium between 6 and 24 hours.

See the scientific wording

A proprietary blend of fruit and vegetable fibers rich in bound polyphenols (NatureKnit™), administered at 1.667 g/L in a simulated human colon model using fecal inoculum from three healthy donors, significantly increased total short-chain fatty acid production by 29.2 mM between 6 and 24 hours, surpassing the increases observed with inulin and psyllium, suggesting a stronger prebiotic effect on microbial metabolism in vitro.

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 them as food to produce short-chain fatty acids. This slow breakdown keeps food available all the way to the far end of the colon, allowing more types of good bacteria to grow and make more fatty acids, while reducing harmful byproducts from protein breakdown.

    In a lab test that mimics the human colon, a fiber blend made from fruits and vegetables made more healthy gut acids than common fibers like inulin and psyllium, suggesting it’s better at feeding good bacteria.
