Summary

This study tested whether hydroxytyrosol, a natural antioxidant found in olives, can reduce inflammation and oxidative stress in pregnant women with high blood pressure. 42 women took either a daily 10 mg hydroxytyrosol capsule or a placebo for 4 weeks. Researchers measured changes in blood markers of inflammation and blood pressure to see if the supplement offers any benefit.
