Optibac One Week Flat

Optibac One Week Flat is a flavourless live cultures supplement in easy-to-take sachets, designed for use over one week or on an ongoing basis. It contains four well-researched strains from the Lactobacillus, Bifidobacterium, and Lactococcus genera, including Lactobacillus acidophilus/helveticus Rosell-52 and Bifidobacterium bifidum Rosell-71. These strains have been scientifically studied and shown to reach the gut alive.

The formula also includes FOS (Fructooligosaccharides), a prebiotic fibre that feeds beneficial bacteria naturally present in the gut.

Free from gluten, yeast, added sugars and artificial flavourings, this supplement is also suitable for individuals with dietary sensitivities or those looking for a gentle, daily live cultures option - including people who may experience occasional digestive discomfort such as bloating. It is suitable for vegans, vegetarians, pregnant and breastfeeding women, and those with coeliac disease.
