Helped relieve my fatigue
Wow, life-changing. The prebiotics have helped tremendously with fatigue — not at all what I was expecting. My gut doctor told me to eat kiwis to help with digestion and that was not always easy to do so I looked for kiwi supplements and WOW. I haven't noticed any digestion changes but I'm guessing it relieved inflammation or something that I didn't realize I had, because I can now get up easier in the morning. I'm not necessarily more energized, but before these, if I didn't get enough sleep, it was devastating. Now I'm fine, I can get through it. I'm very thankful to have found these and now am more conscious of the affect food has on my energy levels.

Not much change
These capsules are really easy to swallow they're not huge. There is no taste, and you can take them anytime of day. I really didn't notice any difference, maybe a little more regular in the bathroom so that would be better gut health but I can't say that it has a lot of health benefits that I've noticed. I have used the whole bottle. It's a good value if it does help you.

It did work but I didn’t see health benefits
I’ve been taking the prebiotic kiwi fiber to fix my gut dysbiosis. I bought 7 bottles of this stuff and took it for months. Recently I gained a bunch of weight like 20 pounds in 3 months due to unknown causes and ballooned up like a pregnant woman. I suspect I have SIBO. I don’t think this pill did anything to help so I’m going to stop buying it and just eat more fruit. It’s very expensive. Taking probiotics gave me more noticeable results. I do want to mention I did a gut stool test and my Faecalibacterium prausnitzii count did double and increase after taking this for over half a year. I’m not sure if it achieved anything however. I did not feel healthier or lose any weight from taking this. No difference.

Good results
To be honest, I wasn't expecting results when I tried it, but to my surprise, it made a noticeable difference! I’ve tried other probiotic supplements before, but this one really stood out for its effectiveness. My digestion feels smoother, and I’ve noticed an improvement in my gut wellness. However, I was disappointed when I couldn't find it for a few months—I really hope they continue making it consistently because it’s become an essential part of my daily routine.
