Wheatgrass for Digestive Health

Research suggests that wheatgrass juice shows the most consistent evidence for digestive health in the context of ulcerative colitis, with a randomized controlled trial and a systematic review of RCTs both finding it superior to placebo in reducing disease activity, rectal bleeding, and supporting remission. Studies indicate that its bioactive compounds — including chlorophyll, antioxidants, and various vitamins and minerals — may help reduce oxidative stress and inflammation in the gastrointestinal tract, with in vitro research using intestinal cell models offering additional mechanistic support. Multiple reviews across the past two decades have noted wheatgrass juice as a recognized complementary option in inflammatory bowel disease, though the same reviews consistently acknowledge that the evidence base remains limited in size and methodological rigor. Overall, while the existing research is directionally supportive, most reviewers caution that more robust and large-scale clinical trials are needed before definitive conclusions can be drawn about its role in digestive health.
