I have tried all kinds of probiotic, digestion, greens, fiber, etc with all kinds of side effects. Some caused more gas, some caused some nasty stuff, and others didn’t do much of anything. Superhuman gut is the 1st gut health supplement I’ve tried with no bad side effects. I also noticed results after only a few doses. I am handling acidic/spicer food better, and just feel generally better throughout the day. Highly recommended!
