product description

Pullulan is a linear polysaccharide produced via sustainable fermentation of Aureobasidium pullulans, a non-pathogenic microorganism widely recognized for its ability to synthesize pure, consistent polysaccharides.

It presents as a white, odorless powder with excellent water solubility, dissolving quickly to form a clear, low-viscosity solution that won’t alter the taste or texture of supplement formulations. Its natural origin and gentle molecular structure make it compatible with various dietary supplement formats—from capsules and powders to liquid blends—suiting diverse consumer preferences for daily intake.

Main Benefits & Functions
As a soluble dietary fiber, it offers three key wellness benefits: first, it supports gut motility by adding bulk to stool and softening it, aiding regular digestion without harsh side effects. Second, it helps maintain healthy blood sugar levels by slowing carbohydrate breakdown and glucose absorption, reducing sudden post-meal spikes—particularly useful for those focused on balanced sugar management. Third, it acts as a protective carrier for probiotics, forming a temporary barrier around beneficial bacteria to shield them from stomach acid and bile, boosting their survival rate until they reach the intestinal tract.

Mechanism of Action
At the intestinal level, Pullulan interacts with water to form a viscous, gel-like matrix. This matrix binds to dietary carbohydrates, delaying their breakdown by digestive enzymes like amylase and slowing glucose release into the bloodstream. It also serves as a fermentable substrate for beneficial gut flora, supporting their growth and activity to maintain a balanced gut microbiome. Its non-digestible nature further promotes healthy colonic transit by retaining water in stool, reducing intestinal transit time—all while maintaining a mild profile that avoids bloating or gastrointestinal discomfort, even with long-term use.
