Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Irritable Bowel Syndrome-Symptom Severity Scale	To determine the efficacy of investigational products on the participants global assessment of gastrointestinal symptoms, as assessed by change in Irritable Bowel Syndrome-Symptom Severity Scale total score at the end of study from baseline compared to placebo.; Each of these 5 items is scored on a visual analogue scale from 0 to 100. Therefore, the total score on the ranges from 0 to 500. Participants are asked to respond to each question on a 100-point visual analogue scale. The higher the scores, the more will be the severity of symptoms. Participants, if required, can be categorized as having mild (75-175), moderate (175-300),; Higher the score is the worst outcome and lower the score is the betterment.	day 0, 28, 56, and 84
Secondary	Bristol Stool Form Scale	At the end of days 28, 56, and 84, the percentage of participants transitioning to normal stool consistency (as demonstrated by weekly BSFS score reported as 3, 4, or 5) compared to baseline scores will be identified to evaluate the efficacy of IP in comparison to placebo.	day 0, 28, 56, and 84
Secondary	Irritable Bowel Syndrome-Quality of Life	Quality of life as assessed by change in Irritable Bowel Syndrome-Quality of Life.; It is a 34-item questionnaire with each item rated on a 5-point scale (34-170), with increasing scores indicating the deteriorating quality of life (Appendix-III). However, to facilitate comparisons among various measures on a standardized scale, the summed scores will be transformed to a 0 - 100 scale ranging from 0 (poor quality of life) to 100 (maximum quality of life).	day 0, 28, 56, and 84
Secondary	Abdominal Pain Severity-Numeric Rating Scale score.	Abdominal pain severity as assessed by change in Abdominal Pain Severity-Numeric Rating Scale (APS-NRS) score.; score ratings include 0 - None, 1 to 3 - Mild, 4 to 6 - Moderate, 7 to 9 - Severe, and 10; = very severe.4	day 0, 28, 56, and 84
Secondary	State-Trait Anxiety Inventory-Adults score.	Mental health as assessed by change in State-Trait Anxiety Inventory-Adults (STAI-AD) score. The State-Trait Anxiety Inventory has 40 items, 20 allocated to each S-Anxiety and T-Anxiety sub-scales . The range of scores for each subtest is 20-80, the higher score indicating greater anxiety. A cut point of 39-40 has been suggested to detect clinically significant symptoms for the S-Anxiety scale	day 0, 28, 56, and 84
Secondary	Vitals - blood pressure	To evaluate the safety of IP consumption .; Normal BP ranging Systolic120 - 129 mmHg and or diastolic 80 - 84 mm Hg	day 0, 28, 56, and 84
Secondary	Gut microbiome as assessed by 16S rRNA sequencing of faecal samples.		day 0 and 84
Secondary	Vitals - Pulse Rate	Normal Pulse rate 60 - 100 bpm	day 0, 28, 56, and 84
