Nutraceutix, Redmond, WA, has received U.S. patent No. 8,007,777, “Delivery System For Biological Component,” for BIO-tract dietary supplements containing probiotics. This new U.S. patent is in addition to four international patents already awarded to Nutraceutix for BIO-tract in China, Australia, Russia and Singapore. Several related patents are still pending. BIO-tract tablets protect probiotics from damaging stomach acids, then release live organisms over time to the upper and lower intestinal tracts for optimal effectiveness.
