Bifido & Fibre contains the probiotic strain Bifidobacterium lactis BB-12® with 4g of prebiotic fibres which together help to promote healthy bowel movements by lubricating the colon, moistening the stool and encouraging healthy peristalsis. It therefore tends to be a good product for anyone who suffers from constipation. This strain of bacteria has recently been featured in one of the largest clinical trials on probiotics, and found to improve bowel regularity.
