GUTGARD™ CLINICAL STUDY
Study Overview
50 adults with functional dyspepsia participated in this 30-day double-blind, placebo-controlled study
Published in Evidence-Based Complementary and Alternative Medicine, 2012
What They Tested
Researchers wanted to see if GutGard (the specialized licorice extract in Kiss My Acid Goodbye) could effectively reduce digestive discomfort and improve quality of life for people suffering from functional dyspepsia—a condition that includes symptoms like upper abdominal pain, bloating, heartburn, and early fullness.
Who Participated
- 50 men and women with functional dyspepsia
- All participants had at least 4 digestive symptoms that significantly impacted their daily lives
- Average age ranged from 38-45 years old
How the Study Worked
- Double-blind design: Neither participants nor researchers knew who was getting the real treatment vs. placebo
- Duration: 30 days of treatment (75mg twice daily)
- Measurement: Participants rated their symptoms using validated questionnaires and quality of life assessments at the start, middle, and end of the study
The Results That Matter to You
Symptom Relief
- Significant reduction in total symptom scores on both day 15 and day 30
- 56% of GutGard users showed marked improvement vs. 0% in the placebo group
- Only 4% of GutGard users had unchanged symptoms vs. 56% in the placebo group
Specific Improvements
Participants experienced notable relief in:
- Upper abdominal fullness and pain
- Heartburn and regurgitation
- Bloating and belching
- Nausea and loss of appetite
Quality of Life
- Significant improvement in daily functioning and overall well-being
- Better ability to eat and drink normally
- Reduced interference with work and daily activities
- Less tension and worry about digestive symptoms
Safety
GutGard was well-tolerated with no treatment-related side effects reported during the entire study period.
What This Means
This study proves that GutGard doesn't just provide temporary digestive relief—it significantly improves multiple aspects of digestive function and quality of life. Participants could eat more comfortably, worry less about their symptoms, and get back to enjoying their daily activities without constant digestive distress.
The Bottom Line
GutGard demonstrated superior effectiveness compared to placebo in reducing digestive symptoms and improving quality of life. The improvements were noticeable within just 15 days and continued to get better throughout the 30-day study period, showing both quick relief and sustained benefits.
