Probiotic Advantage Extra Strength offers natural relief for chronic digestive issues, releasing 10 billion probiotics slowly along both your small and large intestines for guaranteed all day effectiveness. If you have chronic digestive issues, this is the formula for you. I developed Probiotic Advantage Extra Strength so it contains 10 billion healthy, live bacteria in the 10 most powerful Lactobacillus and Bifidobacteria strains for advanced relief. Probiotic Advantage Extra Strength gives you all the same benefits as Probiotic Advantage, including the new BIO-tract extended release delivery system that releases the probiotics slowly. Plus, BIO-tract keeps the delicate live probiotic bacteria intact so they get to your intestines safely. Probiotic Advantage Extra Strength also contains Actazin, a powerful kiwi fruit extract from New Zealand?which provides prebiotics, enzymes, and insoluble fiber. All of these ""digestive boosters"" work together to strengthen the probiotics?to give you advanced support for healthy digestion and improved regularity. If you haven't found relief with other digestive solutions, I encourage you to give Probiotic Advantage Extra Strength a try. You'll notice that the combination of probiotics, prebiotics, fiber, and enzymes can restore balance?even if you have the toughest digestive issues. All it takes is one Probiotic Advantage Extra Strength tablet in the morning for trouble-free digestion all day long. BIO-tract Delivery Technology: Many probiotics deteriorate due to stomach acid. Some probiotics make their way to your small intestines. Extra-Strength Probiotic Advantage delivers healthy bacteria to your entire digestive system?from your small intestine to your large intestine. You get guaranteed full coverage!
