This bottle of Probiotics by Vitamatic is Made in the USA with Strict GMP {Good Manufacturing Practice} Standards. These words jumped out at me right off the Sellers page on ZeeBooth. These are important words which possibly mean that you can trust that the contents are what they say they are; and that the makers followed GMP while making them. I got these Probiotic/Inulin capsules to help out my digestive tract. Bacillus Subtilis is the only Probiotic listed on the bottle. It is naturally present in the gut. These are delayed-release capsules which means that they help protect the live Probiotic thats inside from stomach acid. That way, the B. Subtilis can make it down into the intestines while still alive to support your digestive health. The Inulin is a Prebiotic Fiber which has benefits such as helping to: manage diabetes, improve constipation and digestive health, and promote weight loss. These capsules are about 3/4 long and very slender. They dont smell or taste at all, to me. There are 10 billion CFUs of Bacillus Subtilis in each capsule, along with 300mg of Inulin. You only have to take 1 slender capsule each day. With 60 capsules in the bottle, thats 2 months of worth of servings/doses. This seems to be a very good supplement that is manufactured well. I plan to continue taking these for as long as I can.
