Supplements for Postoperative Nausea

What the Research Shows

Research into supplements for postoperative nausea shows limited but promising results. Currently, peppermint is supported by moderate evidence as a helpful option for reducing the frequency and severity of nausea following surgery. However, most clinical trials in this area are small, meaning the results may not apply to everyone. Evidence for other common supplements remains insufficient or conflicting. While some individual studies suggest benefits from ginger or vitamin B6, larger systematic reviews often find the data inconsistent or too weak to make a definitive recommendation. Many studies suffer from small sample sizes or a lack of standardized protocols, which limits the ability to draw firm conclusions about their effectiveness.
