Seriously after ONE use of these probiotics I saw an improvement in my daughters GI issues. When she was born she was in the nicu for a few days and was on antibiotics the entire time. I think this wiped out all of the good bacteria in her gut. Evivo is definitely doing the job at restoring her good bacteria!! She’s been on it for almost a month now and is like a brand new baby. No more tummy issues, fussiness, or pooping issues! I would highly recommend!
