Obese BMI (30-35) Dietary Supplement: Synbiotic
Synbiotic dietary supplement in capsule form




Primary Outcome Measures :
  1. Measure change in gastrointestinal symptoms using "Rating of Gastrointestinal (GI) Symptoms" scale [ Time Frame: Baseline, Day 28, day 49, day 77 ]
    Rating of GI Symptoms scale includes 5 questions, which range from 0 (never affected) to 7 (always bothered), summed to compute total score

  2. Change in microbiome stool diversity [ Time Frame: Baseline, Day 28, day 49, day 77 ]
  3. Change in metabolome stool profile [ Time Frame: Baseline, Day 28, day 49, day 77 ]
  4. Change in metabolome urine profile [ Time Frame: Baseline, Day 28, day 49, day 77 ]
