    Started taking this about 6 weeks ago. I love it. First of all, the price is right and it gets delivered right to my door. I bought this as well as Vitamin D and B12. I had a question regarding the proper way to take so I reached out. They got back to me quickly and cleared it all up for me. I'm super happy I made the switch!

    I just finished my first Gut Instinct and loved it! I was noticing a lot of bloat and was feeling quite uncomfortable throughout the day and once I started taking Gut Instinct, I felt less bloat and more regular.

    So I have always had constipation most of my adult life. I was having to take miralax atleast once a week before I started gut instinct. Now, I go once if not twice a DAY! And I’m only on my second month. It’s insane how much this has changed my life! Could not recommend this enough!

    I've always heard mixed reviews about taking probiotics, but I was eager to give Gut Instinct a shot. I had read that everything starts in the gut and balancing this could help with hormones, mood, and just all around health. After almost 2 months of taking it, I do feel like it has made a significant difference in my mood and mental state. I feel all around less stressed and seem to have more energy. I don't mean crazy energy, but just a good healthy amount to carry me through the day (which I didn't always have before).

    I’ve only been taking them a few days like 7-10 and so far I’m worried because I feel more bloated and constipated. I normally bm 1/2 per day it was 2 days before I had my first bm after I started taking them and I’ve had gas pains and bloating hopefully it’s just my body getting used to it . Anyone else have this happen?

    This one has been my favorite so far, it is especially easy because it is once a day. I have felt much better since taking it and have been looking for a probiotic that I liked for a long time.

    I have been taking this for a couple of months and can really tell a difference in my stomach. Not nearly as much bloating and more regularity.

    Finally regular and take on an empty stomach in the morning. It’s great to pair with flatter me sometimes when I’ve been eating heavy and bloated. The best probiotics I’ve ever had and Ive spent so much on pre and probiotics that did not work.

    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.

    I have had belly issues for the majority of my life and these probiotics are great! I take it on an empty stomach with no problem.
