Live bacteria are sensitive to changes in environment, so to remain viable in supplement form they need to be adequately protected during their journey to the gut. Gummies or liquid live bacteria don’t have the protection to survive the harsh conditions of the stomach like capsulated forms. Gummies and liquid live bacteria products are also likely to contain sugars, calories, additives and flavourings. Some products suggest opening their capsules and sprinkling the content over food, this however, raises questions over survivability, too.
