The Improving Effects of French Maritime Pine Bark Extract on Antioxidation and Anti-inflammation a in Post-menopausal Women Based on Nutrigenomic Approach

29 settembre 2026 aggiornato da: Taipei Medical University

The goal of this clinical trial is to investigate whether French maritime pine bark extract (FMPBE) supplementation can improve antioxidant capacity and reduce inflammation in postmenopausal women aged 40-75 years.

The main questions it aims to answer are:

Does FMPBE supplementation improve antioxidant status and reduce oxidative stress? Does FMPBE supplementation reduce inflammatory responses and affect related gene expression? Researchers will compare an FMPBE treatment group with a placebo group. Participants will take one capsule daily for 30 days and undergo blood collection on Day 0 and Day 30 for biochemical and gene expression analyses. Participants will also complete assessments of anthropometric measurements, blood pressure, dietary intake, and quality of life.

Sperimentale: French maritime pine bark extract

Dietary supplement: French maritime pine bark extract(contains sesamin 100 mg per capsule) This group will be given supplements for 30 days.

participants who meet the inclusion criteria will be randomly divided into Placebo (P) and treatment (T) groups. Participants in the P group will be provided with one capsule of placebo without FMPBE whereas participants in the T group will be provided with one capsule of placebo with FMPBE (100mg) per day for 30 days. Blood samples will be collected on Day 0 and Day 30 for biochemical and genetic analyses, accompanied by the administration of a quality-of-life (QoL) questionnaire to assess participants' overall well-being. At the same time, they will accept the measurement of anthropometric measurements and blood pressure, also be interviewed with 24 hours dietary recall questionnaire.
