I have struggled with gut issues for 20 years. I tired everything. I went to different gastroenterology doctors and never could find something that helped. Call it fate, or just good timing, but I was desperate as I just turned 40 and was seeking normalcy. No more bloating, not more inconsistency. I stayed taking GUTR3BUILD and for the first time in my life I have consistency with my gut and bowl movements. It was the magic pill I never knew was out there. I never try new things, but happy I did this one. I’ve never felt better.

I took my first full serving yesterday around 5 pm and really started seeing the results today around 11 am. Pardon the crudeness of my description but I would say I pooped out 4/5 pounds. The supplement beautifully flushed out my system. Post using the bathroom I felt energized and light. I’d highly recommend this supplement to everyone regardless if they think they need it. I have a relatively healthy diet and have been seriously lifting and taking care of my body for about a year and a half now and even with taking care of my body and eating healthy, I see monumentos change not even 24 hours into being on the supplement.

Really helped with my bloating and I've noticed I'm much more regular. I just feel better overall, and it's become part of my daily routine. Highly recommend if you're looking for something to support your digestion!

I have been taking Gut R3BU11D from Carna Nutrition for the last 3 months, and it has become an essential part of my daily routine. The flavor iis not chalky and mixes well in my water bottle.
I have suffered from IBS-C for over 20 years; nothing has helped except Gut R3BU1LD. My trainer at hardbodyz in Verona nj suggested I try this because it has gut supportive ingredients. After 3 months of consistent use, my digestion feels so much more balanced and not bloated. This is not a cure, I feel good. I keep a can at work and home; also traveled with this product. Highly recommend!
