TB12 Probiotic helps keep your digestive system in balance with eight strains of potent probiotics plus a prebiotic fiber. When in equilibrium, your gut microflora helps your intestines maximize nutrient absorption and keeps your metabolism fine-tuned. Stay in equilibrium with the 15 billion live beneficial microorganisms in every TB12 Probiotic capsule. These organisms support a healthy intestinal tract and immune system. Clinical trials show that exposure to microbes through the gut may strengthen immune function. Developed without unnecessary fillers and ingredients, our Probiotic is certified for quality and safety by the NSF Certified for Sport Program and has been tested for more than 272 banned substances. HOW TO TAKE: Consistency is key when it comes to a probiotic. Take 1 capsule daily with a meal. Over time (approximately 30-60 days), 15 billion beneficial live organisms will work synergistically to help support a healthy intestinal tract, immune system, and optimal nutrient absorption.
