One Week Flat is a food supplement containing natural bacteria (live cultures), in powdered sachets to be taken daily as a one-week course. This can be taken once a month, or as frequently as desired.
Lactobacillus acidophilus Rosell-52:
Acidophilus is a natural resident of the intestinal microflora; this strain of acidophilus from Optibac has been shown to survive gastric acidity and biliary salts and reach the intestines without damage.
Bifidobacterium bifidum Rosell-71:
In-vitro tests suggest that this strain flourishes well with Fructooligosaccharides.
Lactobacillus casei Rosell-215
Is of an extensively studied species naturally residing in the intestinal flora; this strain from OptiBac Probiotics has been researched in its ability to resist gastric acidity and bile salts to reach your small and large intestines alive.
Lactococcus lactis Rosell-1058
Is extracted from the kefir culture, and has been scientifically proven to reach the gut alive.
Fructooligosaccharide fibres (FOS)
Predominantly settle in the large intestine where they may act as a food source to stimulate the growth of your body's natural bacteria.
This 7-day course is ideal if you're looking for a short-term, high-quality natural bacteria supplement.

Optibac One Week Flat - 7 Sachets
Took one sachet a for a week, then moved on to Everyday capsules. Seems to have settled the excess wind and very unsettled stomach that has been a problem since my gallbladder removal. Would recommend giving it a try.

Optibac One Week Flat - 7 Sachets
Started to see an improvement after the second dose. I wouldn`t hesitate to buy this again- if you have trouble with gut acidity levels this could be a better choice as there are no capsules or coatings to dissolve in the stomach. You get 100%.

Optibac One Week Flat - 7 Sachets
Works well for me taking 1 satchet every 3 to 4 days, or better yet 2 satchets in one go once a week. I must say that taking Triphala is showing more longer-lasting effects.

Works wonders! Deflates a bloated bely in just a few days. I take last thing at night in a glass of water before bed so it can work it`s magic. Also excellent for healing bladder infections.

I love this product it certainly helped me look flatter and fitter after one week enabling me to look great as a mother of the bride recently. I truly recommend it I keep a supply in for any event that I am attending when I want to look slimmer.

I suffered from really bad bloating for weeks, months even. I changed my prescription of lansoprazole and also took a course of OptiBac probiotics. Result! Much flatter stomach and much more comfortable!

Optibac One Week Flat - 7 Sachets
It worked fairly well, I wasn`t expecting a completely flat tummy, but it didn`t work amazingly well for me - in that I wanted it to help control my bloating. I`ve tried most of the Optibac range and this one seemed to work better. Probiotics seem like a minefield to find the right one!

Optibac One Week Flat - 7 Sachets
This has been very successful in treating a long term problem of trapped wind. Having been triggered in the past by any wheat products, I now find that I can widen my range of possible foods. The first positive effects were apparent after 24 hours and the improvement was still there at the end of the month. For me this has been a real life changer.

Optibac One Week Flat - 7 Sachets
It does work after 4th day I noticed the results. No bloating. I then stopped after 7 days and took optibac extra strength but became very bloated and constipated. Back on the optibac 7 day again.
