Acidophilus Pearls™ with patented True Delivery™ Technology protect the Lactobacilus acidophilus and Bifidobacterium longum from stomach acids, and guarantee delivery into the intestine, where they are released intact to increase healthy intestinal flora.† Unlike other enteric-coated products which offer no on-shelf protection (and only minimal protection against stomach acids), patented True Delivery Technology protects the microflora in Acidophilus Pearls from shelf conditions like air and light. Studies show patented Acidophilus Pearls™ deliver up to 900% more intact microflora to the intestine in relation to label claim than 4 leading competitors, including those with enteric coatings.
