TruFiber™ soluble fiber is formulated to stimulate probiotics to restore regularity. TruFiber™ contains two sources of soluble, prebiotic fiber: Sunfiber® and inulin. One serving of TruFiber™ provides slightly more than 14% of the recommended 25 gram Daily Value for fiber. TruFiber™ is a tasteless, white powder that mixes fast and clear with no grit or thickening.

Sunfiber® is derived from seeds of the guar plant and is partially hydrolyzed to improve solubility and reduce viscosity. It has been clinically demonstrated to improve regularity at levels corresponding to two servings of TruFiber™.

TruFiber™ contains the Fiberase™ complex of fiber digesting enzymes. These enzymes are not produced in the human body but occur naturally throughout the plant kingdom. Fiberase™ enzymes are called bifidogenic because they improve the prebiotic activity of fiber present in fruits, vegetables and whole grains resulting in enhanced stimulation of Bifidobacteria. Fiberase™ enzymes are also lactogenic meaning they stimulate the growth of various Lactobacillus probiotics (patent pending).

The two prebiotic fiber sources in TruFiber™ stimulate both Bifidobacteria and Lactobacillus probiotics by directly providing a microbial food source within the intestinal tract. The Fiberase™ enzyme complex improves the prebiotic activity of whole foods in the diet by partially digesting their long chain fiber residues and provides time-released microbial nutrition.

TruFiber™ has been shown to improve the following conditions:

  • Constipation and poor elimination
  • Diarrhea and loose stools
  • Poor absorption of calcium and magnesium
  • Low Bifidobacteria levels in colon
  • Low Lactobacillus colony forming units (CFU) in small intestine
  • High cholesterol and triglycerides

The most common response to taking TruFiber™ is improved regularity with more uniform stool consistency and intestinal comfort.
