OptiBac Probiotics One Week Flat (formerly known as For a Flat Stomach) 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 to 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 has been researched for its ability to resist gastric acidity and bile salts in order 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.

This seven-day course is ideal for those looking for a short-term, high-quality natural bacteria supplement.

Suitable for vegetarians. Free from gluten and yeast.
