Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this clinical trial is to evaluate the effect of hydroxytyrosol 10 mg/day administered for 4 weeks in pregnant individuals with hypertension. This study will assess whether hydroxytyrosol increases serum superoxide dismutase levels, reduces uterine artery Doppler pulsatility and resistance indices, and improves brachial artery flow-mediated dilation.

Participants will be randomly assigned to receive either hydroxytyrosol or a matching placebo. Both products will be visually identical to ensure blinding. Participants will take two capsules daily for 4 weeks and attend two study visits for assessments and follow-up.

This study uses identical capsules for hydroxytyrosol and placebo to maintain masking of all parties.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Placebo Group

Participants in this arm will receive a placebo capsule orally twice daily for 4 weeks, alongside standard antenatal care. The placebo is visually identical to the hydroxytyrosol supplement to maintain masking.

Placebo

Intervention Type DIETARY_SUPPLEMENT

Placebo oral capsule identical in appearance to hydroxytyrosol supplement, administered twice daily for 4 weeks.

Hydroxytyrosol Group

Participants in this arm will receive hydroxytyrosol 10 mg orally twice daily for 4 weeks, alongside standard antenatal care.

Group Type ACTIVE_COMPARATOR

Hydroxytyrosol

Intervention Type DIETARY_SUPPLEMENT

Hydroxytyrosol is a natural polyphenol with antioxidant and anti-inflammatory properties, derived from olives. In this study, hydroxytyrosol 10 mg will be administered orally twice daily for 4 weeks to assess its effects on blood pressure and inflammatory biomarkers in hypertensive pregnant women.
