Sea Buckthorn for Constipation

A 2026 study found that a 500mg extract of sea buckthorn significantly improved chronic idiopathic constipation compared to placebo over 28 days. Mean change in spontaneous complete bowel movements improved from 1.5 to 2.6 per week. There were also significant improvements in stool consistency, bloating and abdominal pain. Some people may be allergic to sea buckthorn. Sea buckthorn may cause digestive or other side effects.
