Review: Brilliant product which works - Brilliant product. I have gallstones so I deal with a lot of bloating, after a massive weight loss last year my stomach is one area of my body I’m most self conscious about and I was struggling with the area of my body I’m most self conscious about sticking out so I thought I’d try these. As I’m only on day 2 it’s still early days but i definitely feel less bloated after meals I’ve noticed, will see how I get on with the rest of the week but now considering taking these daily.

### ⭐⭐⭐⭐⭐ Brought down the bloating massively. Impressed!
*by S***O on 22 August 2025*

Honestly amazing. My stomach was bloated for quite some time. I had on and off heartburn. Just generally felt rubbish. I bought these because of some of the reviews. They were amazing. I think I had gas stick in my stomach as my tummy was bloated up 2 clothes sizes. By the end of the week, the difference was amazing. I do still have the on and off heartburn but my stomach issue has been sorted. Will take this every 6 weeks to keep on top of everything or just keep a box on stand by. There is practically no flavour at all, a bit like potato starch. Drank it to problem. It doesn't always dissolve but it does work, so not fussed about that really. 5 stars for sure. I lost 2 kgs but unsure if it was to do with stored gas etc but was pleased anyway. Tgat was 6 weeks ago and gas stayed off. My friend tried it for meno belly and was also pleasantly surprised after telling me it was probably rubbish. Shebus very happy. I think the stomach needs a prebiotic/prebiotic from time to time to align it. If in doubt, definitely give it a go.
