The Advanced Formula Complete probiotic from Pinnacle Nutrition is as described on the product description page. The bottle contains 60 capsules. The recommended dosage is 2 a day (preferably one in the morning and one at night). When taken as recommended this is a 30 day supply of the healthy gut bacteria. How do you really judge a good probiotic for your healthy gut? Do as I do and change the brands each month. Doing so will provide you with different types of the organisms or good bacteria in the various brands. I love that there are 40 billion organisms in these easy to swallow caplets and they are made in the USA. Having a healthy gut is crucial to your overall health. I keep my probiotics in the refrigerator to keep the organisms active. I received this one month supply without any cost for my use and evaluation.
