Each subject then had a washout period of between 3-9 weeks.
At the third study visit (Visit3) the second treatment was allocated and a further
4 week supply of capsules provided, and GSRS and
SF-12 pre treatment questionnaires were administered.
After 3 weeks participants then returned to the clinic for
the fourth study visit (Visit4) with completed faecal diaries,
leftover capsules, and to complete post treatment questionnaires.
