Adverse Event Assessment At each visit, participants will be asked an open question as if he/she has experienced any abnormal symptoms. Any symptom reported by the participants will be recorded as an adverse events with details of the event, its severity, start and stop dates, and relationship to study products. Gastrointestinal symptoms (heartburn, distension, nausea, vomiting, abdominal pain, flatulence, constipation and diarrhea) within 24 hours after OSTT will be asked and recorded as well.
