Trace® Minerals Probiotics is a 10-strain formula that carries 55 billion cultures in each capsule, giving your gut flora the support and care they need. As we age, intestinal flora decreases which can cause digestive systems to function incorrectly. This prevents nutrients from food from being broken down and absorbed properly. Taking a probiotic not only keeps this process going, but nourishes the friendly bacteria in your digestive system to keep it healthy. These delayed-release capsules are designed so that the probiotics aren't damaged by stomach acids, allowing them to reach the small intestine for maximum effectiveness.
