Our highest strength blend of 6 scientifically backed live bacteria; Lactobacillus acidophilus, casei and plantarum, alongside Bifidobacterium lactis and bifidum, and Streptococcus thermophilus. Perfect for more comprehensive support. Our gut microbiome, or gut flora, is made up of over 100 trillion bacteria. There are around 1-2 kilos of bacteria living in the gut of an average adult. This internal eco-system is responsible for a whole host of roles. The delicate balance of these friendly bacteria is often upset by antibiotic use, stress, poor diet, poor sleep and shift-work.
