So far, this seems like a very good product with no aftereffects of gas or bloating. It's easy to swallow, and it's recommended to take one at both lunch and dinner. I noticed in a previous review that the capsules contain magnesium stearate and silicon dioxide, but my bottle does not have these ingredients. Instead, it lists vegetable capsule hypromellose (a cellulose binder), water, and medium-chain triglycerides (MCT), which usually come from coconut or palm oil. The PreforPro is a highly recognized prebiotic technology, so this product seems to provide quality support to my digestion. Overall, I am pleased.
