Belly Mend will not colonize like a traditional probiotic. It contains beneficial bacteria that have been cell wall lysed (decimated), releasing the vital substances and nutrients from the cell wall and cytoplasm directly into the solution. These immune system modulators exist inside the cell of healthy probiotics and are not readily available in most probiotic formulas. This proprietary manufacturing process makes Belly Mend a unique probiotic tincture. Belly Mend also contains micronized chlorella which increases lactobacillus in the gut. This formula is an excellent food source (prebiotic) for live beneficial bacteria. Belly Mend may be used on its own or with a colonizing probiotic.
