|Condition or disease||Intervention/treatment||Phase|
|Gastrointestinal Symptoms||Dietary Supplement: GlutenShield Other: Placebo||Not Applicable|
The purpose of this research is to identify if there is a relationship between GlutenShield, a combination prebiotic, probiotic, and enzyme supplement, and the gut environment.
The study will be a split, 28-day randomized, partially blinded design. Subjects will be randomly assigned to one of two groups. One group will complete a 28-day treatment period with GlutenShield taken 3x/day with meals. The other group will complete a 28-day placebo period with the placebo taken 3x/day with meals. The placebo will contain Avicel (cellulose) and bentonite powder (to have a similar color as GlutenShield). Participants will be blinded to which group/ treatment they are being given. Serum and fecal samples will be collected at baseline and on day 29. Participants will also complete a gastrointestinal symptoms questionnaire, a food frequency questionnaire and a psychosocial measures of self questionnaire.

3 capsules of GlutenShield supplement/day for 28 days
Dietary Supplement: GlutenShield
combination probiotic, prebiotic, and enzyme supplement
Placebo Comparator: Placebo
3 capsules of the placebo (Avicel and bentonite powder (for color))/ day for 28 days
Avicel (cellulose) and bentonite powder
- Change in Fermentation Profile- Short Chain Fatty Acid Concentration [ Time Frame: Baseline and Day 29 ]Measuring change short chain fatty acid concentrations in fecal matter (analyzed using gas chromatography) from baseline to after 28 days.
- Change in Microbial Population and Concentration [ Time Frame: Baseline and Day 29 ]Measuring change from baseline of fecal microbial populations and concentrations (using genomic sequencing).
- Change in Inflammation [ Time Frame: Baseline and Day 29 ]Measuring change in serum markers of inflammation (IgA and IgG, GM-CSF, IFN-γ, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-α) over 28 days. Values will be used to determine a change in overall inflammatory status.
- Dietary Intake [ Time Frame: Baseline ]Identifying typical dietary intake over the past month using Block Food Frequency Questionnaire
- Physical Activity [ Time Frame: Baseline ]Identifying typical physical activity over the past month using Block Food Frequency Questionnaire
- Change in Oxidative Stress [ Time Frame: Baseline and Day 29 ]Measuring changes in serum markers of oxidative stress (8-isoprostaglandin F2a)
- Changes in Psychosocial Measures of Self [ Time Frame: Baseline and Day 29 ]Measuring changes in psychosocial measures of self (Profile of Mood States 2nd Edition survey)
- Changes in Adipokine Response [ Time Frame: Baseline and Day 29 ]Measuring changes in adipokine response (Bio-Plex Pro Human Diabetes Adipsin and Adiponectin assays)
