About this study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • French maritime pine bark extractDietary supplement

    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.

Questions about this trial

What is this clinical trial studying?

A study testing French maritime pine bark extract in people with Gene Expression and Nutrigenomics, run by Taipei Medical University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 2 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Baseline quality-of-life (QoL) in 30 days (time frame: At the start of the experiment and at the Day 30). The study lists 11 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2026.
