  • This product is a total game changer. I’ve tried all the opti bac products but this one seemed to agree with me the most and I now take these daily. The sachets make my bowels regular, which is something I’ve struggled with for years. The opti bac team have been great with their customer care and have been committed to helping me find a product that works for me. Thank you!

  • This is such a fantastic product to have in the cupboard for that time of the month bloating! I've suffered from bloating and flatulence in the week leading up to my period since I was in my teens. A friend of mine recently recommended 'One week flat', and it's really helped do just that. What a relief... thank you OptiBac Probiotics!

  • I gave birth to my 2nd child a little over two months ago and I’ve always had a little podgy stomach since I can remember. I have pcos which makes loosing weight a bit harder. I only lost half a stone since having my daughter, im now a size 10-12, 10 1/2 stone, I’m only 23 this year and have been doing exercises and eating more home made meals but I still feel so fat. I feel like it’s all mainly bloat though so I tried these and have been having two a day for the past wk to kick start it, maybe that’s why I didn’t see any different but I don’t think my stomach is any different. I’m going to buy one more box and try it one a day as it says as my body is quite arrogant and it’s hard to loose weight maybe one wk just isn’t enough, I’ve tried everything I really thought these would work and was really hoping they would.

  • How to use

    Recommended use

    Natural dietary supplement suitable for adults and children (from 4 years onwards) with the following recommendations:

    • Take 1 sachet daily for 7 consecutive days, preferably with breakfast.
    • Pour an inch of water into a tall glass, leaving plenty of room for swirling.
    • Shake the sachet before gently sprinkling the powder into the glass.
    • Vigorously swirl the water around in the glass making sure the powder is dissolved.

    We highly recommend you take One Week Flat for 7 consecutive days. Many consumers like to take this course once a month. However, it can be taken on an ongoing basis or as desired.

    Storage

    • Store in a cool, dry place below 25°C (77 °F) and out of direct sunlight.

    Safety

    Probiotics are not recommended for those with serious medical conditions e.g. those who are severely immunosuppressed, have pancreatitis, are in the ICU, have melaena, have a central venous catheter, infants with short bowel syndrome, or patients with open wounds following major surgery; unless under a doctor's care. Keep out of reach of children.

    This is a dietary supplement and is not intended to prevent, treat or diagnose any medical conditions. Probiotics for bloating should not be used as a substitute for a healthy diet and lifestyle. If you are taking any medications or have a serious medical condition, consult a doctor before use. Optibac supplements will not cause dependency and may be used on an ongoing basis.

Many probiotic strains, including those found in Optibac Probiotics One Week Flat, produce digestive enzymes. These digestive enzymes are known to help break down problematic foods, preventing excessive fermentation in the gut that can cause bloating(1)*. The good bacteria in the supplement also help to discourage the growth of undesirable bacteria(2)* which tend to product a lot of gases. For these reasons, many people find that One Week Flat can be helpful for occasional bloating*.​

Initially it’s best to take Optibac Probiotics One Week Flat daily for one week to complement and balance your natural gut bacteria*. After that, people take a week’s course every month, or whenever they feel they need support for occasional bloating*. Others prefer to take one sachet every day on an ongoing basis. All of these options are absolutely fine! See what suits you best.

Optibac Probiotics One Week Flat is dairy and gluten-free, so is fine to be taken by people who suffer with food-related bloating or lactose intolerance(1,2,3). This high-quality supplement contains four, highly researched probiotic strains combined with natural prebiotic FOS fibres, which together help to support the gut microbiome and gently help you to more easily digest problem foods*.
