Even with a healthy diet and regular exercise, many of us can still experience low energy levels and poor digestion function from time to time. The OptiBac ‘For every day MAX’ Probiotics aim to give you a daily gut booster (not as painful as it sounds). They contain the strains of probiotics that have been researched in vitro and clinical trials and were proven to help gut health. The OptiBacs are sugar, fat and flavouring free and contain 50 billion live microorganisms combining three strains: L.acidophilus NCFM, B.lactis HN019 and B.lactis BI-04.
