Effects of Ricinoleic Acid (Castor Oil) on Gut Permeability in Healthy Participants: Provocative Test for Treatments Aimed at Restoring Barrier Function.
Introduction: Altered intestinal permeability (IP) is implicated in multiple gastrointestinal and systemic disease conditions; an experimental model of perturbed IP in healthy subjects is needed. Traditional approaches to perturbing IP include use of nonsteroidal anti-inflammatory drugs (NSAIDs).
Methods: We conducted a single-center, randomized, placebo-controlled pilot study of dose-related effects of CO (and its ingredient ricinoleic acid [RA]) at 750, 1500, or 3000 mg daily doses on IP. Permeability was assessed using validated 13C-mannitol and lactulose urine excretion at 0-2h, 8-24h, 0-24h after oral administration.
Results: Permeability analysis across all groups demonstrated significant difference among the groups for 0-2h 13C-mannitol, 0-24h 13C-mannitol, and borderline significant difference for 2-8h 13C-mannitol (p=0.060) and 0-24h lactulose (p=0.056). Direct comparison of 3000 mg CO vs. placebo (t-test) demonstrated higher excretion of 13C-mannitol and lactulose at 0-2h, and 0-24h, and lactulose at 2-8h.
Conclusion: CO may perturb small intestinal and colonic permeability in healthy adults.

Clinical and Translational Gastroenterology (CTG), published on behalf of the American College of Gastroenterology (ACG), is a peer-reviewed open access online journal dedicated to innovative clinical work in the field of gastroenterology and hepatology. CTG hopes to fulfill an unmet need for clinicians and scientists by welcoming novel cohort studies, early-phase clinical trials, qualitative and quantitative epidemiologic research, hypothesis-generating research, studies of novel mechanisms and methodologies including public health interventions, and integration of approaches across organs and disciplines. CTG also welcomes hypothesis-generating small studies, methods papers, and translational research with clear applications to human physiology or disease.
