Primary Outcome Measures
NameTimeMethod
To assess the effect of the IP on gastrointestinal digestion symptoms as assessed by the change in digestive domain scores of the Gastrointestinal Quality of Life Index (GIQLI) compared to baseline and placebo.Day 0, Day 45, Day 90.

GIQLI is a validated tool suitable for assessing health-related quality of life (QOL) in clinical studies of individuals with gastrointestinal conditions and in routine clinical settings. It evaluates both generic and specific upper and lower gastrointestinal symptoms through 36 items. These questions are grouped into five domains: core symptoms (10 items), physical items (6 items), psychological items (6 items), social items (2 items) and disease-specific items (8 items).

The GIQLI total cumulative score for the digestive domain ranges from 0 to 72, with higher scores indicating better gastrointestinal function and quality of life in the context of digestive symptoms

Secondary Outcome Measures
NameTimeMethod
To assess the effect of IP on the following compared to baseline and placebo Gastrointestinal quality of Life as assessed by GIQLIDay 0, Day 45, Day 90

To assess the effect of IP on the following compared to baseline and placebo Stool consistency as assessed by the Bristol Stool Form Scale (BSFS)Day 0, Day 45, Day 90

The Bristol Stool Form Scale (BSFS) is a 7-point ordinal scale of stool types extensively used in clinical and research settings that classify feces into seven groups

To assess the effect of IP on the following compared to baseline and placebo on Percentage responders as assessed by the change in the frequency of BSFS stool types 6 & 7Day 0, Day 45, Day 90

The Bristol Stool Form Scale (BSFS) is a 7-point ordinal scale of stool types extensively used in clinical and research settings that classify feces into seven groups

To assess the effect of IP on the following compared to baseline and placebo on Gastrointestinal symptoms as assessed by the Gastrointestinal Symptoms Rating scale (GSRS)Day 0, Day 45, Day 90

The GSRS is a self-reported questionnaire for GI discomfort. The questions in this scale ask about the severity of a wide range of gastrointestinal symptoms of an individual during the past week. Questions are to be rated on a Likert scale ranging from no discomfort at all (0) to very severe discomfort (3). A total score is calculated by summing the ratings provided on all questions

To assess the effect of IP on the compared to baseline and placebo Intestinal permeability as assessed by serum levels of Lipopolysaccharide binding protein (LBP)Day 0 & Day 90

LPS is detected throughout the body by a specific protein called Lipopolysaccharide binding protein (LBP). LBP then initiates the immune response by presenting LPS to cell surface pattern recognition receptors membrane-bound CD14 (mCDC14) and toll-like receptor-4 (TLR4).

To assess the effect of IP on the compared to baseline and placebo on Inflammation as assessed by Interleukin-6 (IL-6), Interleukin-10 (IL-10) and Tumor Necrosis Factor-alpha (TNF-α)Day 0 & Day 90

Inflammation serves as a natural defensive reaction of the innate immune system triggered by various harmful agents such as microorganisms, trauma, necrosis, chemicals, immune responses, or metabolic stress.

The acceptable ranges proposed are as follows: IL-6 (Not detectable to 50 pg/ml), IL-10 (Not detectable to 8 pg/ml), and TNF-α (2 to 20 pg/ml)

To assess the effect of IP on the compared to baseline and placebo on Intestinal inflammation as assessed by fecal calprotectin.Day 0 & Day 90

The fecal calprotectin a highly sensitive marker for detecting inflammation associated with GI disorders. The concentration of fecal calprotectin correlates well with the severity of intestinal inflammation,The fecal calprotectin range was found to be 18-37 μg /g in IBS individuals

To assess the effect of IP on the compared to baseline and placebo on Microbial metabolic activity as assessed by fecal short-chain fatty acids (SCFA) [Acetate, Butyrate and Propionate]Day 0 & Day 90

SCFAs exert beneficial effects on gut health through various mechanisms. They help maintain intestinal barrier integrity, promote mucus production, and possess anti-inflammatory properties, thereby contributing to overall GI well-being.

These SCFAs range from 20 to 140 mM in the gut, with higher concentrations found in the proximal colon (70-140 mM) and lower concentrations in the distal colon (20-70 mM) and distal ileum (20-40 mM).

To assess the effect of IP on the compared to baseline and placebo on The gut microbiome as assessed by Next Generation Sequencing (NGS)Day 0 & Day 90

NGS allows for a more comprehensive analysis of complex microbial communities compared to traditional culture-based methods. The declining costs associated with NGS have further propelled its widespread adoption in microbiome research. NGS has proven particularly advantageous in elucidating the intricate relationship between the microbiome and various conditions.NGS will be assessed on day 0 and day 90
