    I do agree with some reviews saying the fennel taste has been overwhelming lately. I have been taking these for almost a year, although not regularly. They do work. But the best unintended side effect, it helps with gall bladder pain. I get it once in awhile after eating things like steak, or broccoli, or a fat heavy meal. Take 2 of these beforehand, and no pain. And if by chance I have a gall bladder "attack", which btw can last hours, 2 of these shortens the attack and it's over in 20 mins. Totally unintended by HUM I'm sure.

    This PRODUCT has CHANGED my LIFE! This may be TMI, but I have tried every prebiotic/probiotic, fiber supplements, eating healthier, drinking water in excess, gut cleansers, laxatives, stoole softeners, saline laxatives, dietary supplements, you name it, I have tried it...NOTHING has helped until I found this product...I am currently "regular" for the FIRST TIME in my adult life!!!

    Its not often I write a review but, when I feel a product truly deserves a review I will write one. I have suffered from IBS since I was 16. I have periods of time when I have my IBS under control and times when it's manageable able. The past month has been a rough one as anybody with IBS knows when it's bad it's bad. Even eating what I was supposed to be eating to help with IBS it messed my stomach up so bad instantly when I ate something. I took one of these probiotics and the results from day one are incredible. I would highly recommend these to anyone who is struggling with stomach issues. Lifetime customer here.

    I started using this product when I was recommended by my doctor to start eating a low FODMAP diet and taking probiotics to heal what was going on in my gut. I started using this product and have never been disappointed! It is gentle on my stomach, doesn't smell bad, and reduces my painful bloating. I am super thankful for this product and HIGHLY recommend it!

    Gut instinct to help build the healthy bacteria in my stomach was essential due to my sudden lactose intolerance. I take one of these combined with Daily Cleanse to start my day & at lunch I follow up with Flatter Me. I have no complaints & my stomach digests cheese a lot better now.
