Vitamin B6 among treatments that reduce pregnancy nausea, meta-analysis finds — but low-quality evidence tempers confidence

This meta-analysis adds vitamin B6 to the list of options for pregnancy nausea, but the low-to-moderate quality evidence and limited side-effect reporting mean the true benefit could be smaller, and the lack of a specified dose makes it hard to apply directly.

A comprehensive analysis of multiple studies found that vitamin B6, along with other interventions like ginger and acupressure, may help reduce nausea and vomiting during pregnancy. However, the overall quality of the evidence was low to moderate, and adverse events were not well documented, so these results should be interpreted cautiously until higher-quality studies confirm the findings.

Where this fits in the evidence
