Optibac One Week Flat 7 Sachets

'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. Please scroll to the bottom of the page to read reviews from our customers who have tried this supplement.

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 in 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 where they may act as a food source to stimulate the growth of your body's natural bacteria.

This 7 day course is ideal for those looking for a short term, high quality natural bacteria supplement.

Directions for use:

As a natural food supplement 'One week flat' can be given to adults and children from 4 years old & up, with the following recommendations: Take one sachet daily with breakfast for a 7 day course, or as professionally directed.
