A passion for health and wellbeing inspired three siblings and their father to create OptiBac Probiotics in 2004. A particular focus is placed on how different strains (specific types of live cultures) work differently, and the brand is entirely devoted to live cultures. With OptiBac Probiotics, there are a variety of strains found to help you maintain a balanced digestive system, and every strain is rigorously tested for quality – so you can be confident you’ll receive a high-quality supplement.
