If any of these intake levels cause excessive flatulence then reduce the dose and gradually build up. The flatulence is a positive sign that FOS has reached the bowel and is feeding your ‘friendly’ bacteria. As the bacteria consume FOS a gas is produced which can lead to some flatulence at first, however, after a few days this will disappear as further ‘friendly’ bacteria develop and absorb the gases. For intakes over 10g (or 5g in children); dividing the intake into 2 daily doses, 1 at each end of the day, will help reduce flatulence.
FOS may cause temporary bloating. This is a short-term effect and once your system ‘speeds up’ the bloating will disappear. If bloating continues for more than 3 days then reduce the daily intake of FOS.
