"When you consider the quality of the strains used, and the billions per capsule, Optibac actually offers incredible value for money!"
"I love that the range is tailored for different life stages and needs. It takes into account our individuality - which is important."
"Most people don’t know that the research behind the strains is so much more important than a higher billion count per capsule."
"Optibac use more natural ingredients and fewer additives than most brands. The gummies are made from fruit purees with no added sugar or flavourings – that’s rare!"
"The Optibac range is home to the most researched strains in the world. It feels good being able to recommend supplements that you genuinely believe in!"
"My personal discovery of live cultures started with ‘One Week Flat’ 10 years ago and it’s one I still use and recommend regularly, especially before holidays or festive periods."
