About Vibrant

Up to 1 in 5 American adults — disproportionately women and people of color — struggle with chronic constipation and existing treatments ruin their quality of life with 60 percent saying the treatments, which cause diarrhea, are worse than the constipation. Recently named as one of the best inventions of 2023 by TIME, Vibrant is a new FDA-cleared drug-free treatment that uses a vibrating capsule to restore the colon’s natural rhythm and put you back in control. Clinical results show Vibrant provides one, two and sometimes three additional complete spontaneous bowel movements weekly, even in severe adult patients, with just 1.2 percent of patients reporting diarrhea. Since Vibrant is not a drug, there are no interactions with other drugs, unlike traditional and prescription laxatives. Learn more at
