Impressed! - 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. 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. ## Features - GLUTEN FREE & SUITABLE FOR BLOATING: Optibac are scientifically proven to reach your gut alive - 5 BILLION CFU: Optibac guarantees 5 billion live bacteria + 0.3g FOS fibres in every sachet - SCIENTIFICALLY PROVEN BACTERIA: Optibac uses scientifically studied strains, such as Bifidobacterium bifidum Rosell-71 & Lactobacillus casei Rosell-215 - A VEGAN, MORE NATURAL CHOICE: This digestive supplement is vegan, dairy free, gluten free & free from added sugar, artificial flavourings or colourings - EASY TO TAKE: Take one sachet daily, preferably with breakfast - suitable for women, men and children over 4 years old ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TONLC8S | | Age Range Description | Adult | | Allergen Information | Contains: Gluten Free | | Benefits | Digestive Health Support | | Best Sellers Rank | 1,308 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 8 in Lactobacillus Nutritional Supplements | | Brand | Optibac | | Brand Name | Optibac | | Colour | Clear | | Container Type | Box | | Country Of Origin | France | | Customer Reviews | 4.1 out of 5 stars 965 Reviews | | Diet Type | Vegan | | Dosage Form | Powder Sachet | | Flavour | Natural | | Global Trade Identification Number | 05060086610710 | | Item Dimensions | 7 x 6.5 x 10 centimetres | | Item Form | Sachet | | Item Nype Name | Live Cultures 'One Week Flat' 28 Sachets | | Item Weight | 0.08 Kilograms | | Item form | Sachet | | Item weight | 0.08 Kilograms | | Manufacturer | Wren Laboratories Limited | | Manufacturer Part Number | OPTONEZ10 | | Material Features | Gluten Free | | Material Type Free | Yeast Free | | Model Number | OPTONEZ10 | | Number of Items | 1 | | Primary Supplement Type | Live bacterial cultures | | Primary supplement type | Live bacterial cultures | | Special Ingredients | FOS Fibres | | Specific Uses For Product | Everyone | | Total Servings Per Container | 28.0 | | Unit Count | 28.0 count | | Unit count | 28.0 count | ## Product Details - **Brand:** Optibac Probiotics - **Diet type:** Vegan - **Flavour:** Natural - **Item dimensions L x W x H:** 7 x 6.5 x 10 centimetres - **Item form:** Sachet - **Item weight:** 0.08 Kilograms - **Primary supplement type:** probiotic - **Product benefits:** Digestive Health Support - **Special ingredients:** Probiotic - **Unit count:** 28.0 count ## Images ![One Week Flat, Vegan Digestive Supplement, 4 Wk Supply, 28 Sachets | Suitable for bloating as gluten free | From the UK's most trusted & recommended friendly bacteria brand - Image 1](https://m.media-amazon.com/images/I/71MGjNtyJ7L.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How often should I take Optibac One Week Flat live cultures?** A: Initially it’s best to take daily for 1 week.

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.

About 5 years ago, for no obvious reason my waist shot up by several inches and coping with things like waistbands and tights was nigh impossible. Two or three months ago a dietician immediately diagnosed 'bloating' and suggested I try One Week Flat. The result was astonishing. Within that first week I was back to normal and able once again to get into some of my own clothes which I was close to discarding. And tights are no longer a problem. I am using it one week on, two weeks off. I am unaware of any side effects. But it is important to acknowledge that it really doesn't work for everybody. I would just say, if you have a bloating problem try it. ## Frequently Bought Together - Optibac Probiotics One Week Flat - Vegan Digestive Probiotic Supplement Suitable for Bloating with 5 Billion Bacterial Cultures - 4 Week Supply - 28 Powder sachets - Optibac Probiotics Every Day - Digestive Probiotic Supplement with 5 Billion Bacterial Cultures & FOS Fibres - 30 Capsules - Optibac Probiotics Bifido & Fibre - Vegan Digestive Probiotic Supplement with FOS Fibre to Maintain Regularity & 25 Billion Bacterial Cultures - 30 Sachets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/48838525-one-week-flat-vegan-digestive-supplement-4-wk-supply-28](https://www.desertcart.ro/products/48838525-one-week-flat-vegan-digestive-supplement-4-wk-supply-28) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-21*
