Additional Warnings: When starting to use bacteria or fibres, flatulence and/or cramping can occur. This harmless symptom means that the bacteria have reached the intestines alive and are starting to ferment. Over the course of time (usually a week) the body adapts and the cramps and/or gas will reduce or disappear completely. In the event of complaints, one can reduce the daily dose to half of the recommended amount for the first two weeks.
