Summary
A 44-person randomized trial in Japan found that adults with mild constipation who drank a vinegar beverage daily had about 1.2 more bowel movements a week than a placebo group after four weeks.
The 200-milliliter drink delivered 750 milligrams of acetic acid at breakfast, and researchers said the vinegar group showed earlier improvement in bowel frequency, defecation days and stool volume.
Both groups improved over time, raising the possibility that added daily fluid or better hydration contributed to relief alongside any vinegar-specific effect.
Experts called the findings preliminary, noting the study tested a standardized diluted beverage—not apple cider vinegar shots or supplements—and was funded by vinegar maker Mizkan, which employed three researchers.
Doctors and dietitians said first-line constipation care still rests on fiber, adequate hydration, exercise and bathroom routine, warning that regular undiluted vinegar can irritate the esophagus and erode tooth enamel.
