This is a quality prebiotic fiber for digestive help: 1. They are easy to swallow and had no aftertaste. 2. Being non-GMO and free of gluten, soy, yeast, egg, and artificial colors, flavors, and preservatives makes it suitable for a wide range of dietary preferences and restrictions. 3. I like that this comes in capsule form, making it easy to incorporate into my daily routine. These made in the USA, and certified in a GMP facility, however, I did not see anything about third-party testing. I can't say that I've had any positive or negative side effects from these capsules, but supplements often have subtle effects and take time to be most effective. I'll update this review if anything changes.
