Supplements for Postoperative Delirium

What the Research Shows

Clinical research indicates that certain supplements may help reduce the incidence or severity of postoperative delirium, though evidence varies by substance. Melatonin has strong evidence supporting its use, as it helps regulate sleep-wake cycles and may protect the brain from oxidative stress during and after surgery. Other supplements have shown less consistent results. For example, Omega-3 fatty acids and certain antioxidants have moderate to weak evidence, with some studies showing benefit while others show no significant difference compared to placebos. For many other herbal or vitamin-based supplements, the evidence remains insufficient or conflicting due to small sample sizes and a lack of standardized trials. A major limitation of current research is the inconsistency in how delirium is measured and the lack of long-term follow-up. Because individual responses to supplements can vary based on the type of surgery and a patient's overall health, the current body of evidence is not yet sufficient to establish a universal standard of care.
