Probiotic-10 and Bifido Boost bolster existing gut microflora with ten acid-resistant probiotic strains and nourish them with PreticX, a unique xylooligosaccharide (XOS) prebiotic complex. PreticX specifically nourishes and stimulates the growth of Bifidobacteria and other probiotic organisms found in the gastrointestinal tract, resulting in a healthy and balanced ratio of microflora that promotes intestinal comfort, regularity, and healthy immune system function. It is recommended to take 3 capsules 1 to 2 times a day, preferably on an empty stomach. Consult a doctor if you are pregnant / nursing, taking medications (especially immunosuppressive medications), or have a medical condition (especially if the immune system is compromised). It is not made with wheat, gluten, soy, milk, egg, fish, shellfish, or tree nut ingredients. Produced in a GMP facility that processes other ingredients that contain these allergens. Refrigerate to maintain potency. Keep out of the reach of little kids.
