What You Need to Know Before You Apply

What is the purpose of this trial?

This study will be conducted to determine the effect of daily Tetrasol consumption in supporting gut health using assessments of gastrointestinal symptoms (GSRS) and bowel habits (BSS) as primary outcome measures. The investigators also intend to explore fecal and blood biomarkers of intestinal permeability/function, determination of anxiety and stress levels through both validated assessments and saliva and blood biomarkers, establishment of intervention safety and tolerability through comprehensive metabolic panels and overall compliance, explore the effects of the intervention on inflammation and acute stress (Cold Presser Test), blood lipid profiles, and gut microbiota composition as secondary outcomes.
