IBS Urgency harnesses the therapeutic potential of five probiotic strains, with proline-rich polypeptides from colostrum to alleviate symptoms of irritable bowel syndrome (IBS) that include bloating, gas, diarrhea, and constipation. IBS Urgency is a side-effect-free alternative to prescription drugs for relief of the often debilitating effects of irritable bowel syndrome that include diarrhea, constipation, often embarrassing gas production, and painful bloating. IBS Urgency delivers 10 billion colony forming units of 5 probiotic strains that are critical components of the diverse community of microbes that populate healthy, well-balanced intestines. These probiotic strains of the Bifidobacteria and Lactobacillus genera are necessary for optimal intestinal and immune system function. Altered microflora from broad-spectrum antibiotic use is among the more common causes of IBS symptoms that respond positively to probiotic therapy. The 180 mg of colostrum (standardized to 8% proline-rich polypeptides) amplifies the benefits of IBS Urgency as it calms down inflammation within the intestines that contribute to the symptoms of IBS. Colostrum also promotes the growth of B. infantis: this beneficial strain is the first probiotic to inhabit the infant intestinal tract and is considered by many as the single most important beneficial bacteria within human intestines. The water-based PH5D natural enteric-coated vegetable capsule survives harsh stomach acids to deliver 100% of the therapeutic benefits of each capsule of IBS Urgency.
