About this study

Official title: Evaluation of Oral Bioavailability of the Phenolic Compounds in a Melissa Supplement: Double-blind, Randomized, Crossover Study

The objective of this study is to identify phenolic compound biomarkers of the intake of a mixture of Melissa officinalis extract, acerola extract and vitamin B5. This will be done through the study of their bioavailability and nutrikinetics by measuring their plasma concentrations and urinary excretion over 24h by means of high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The study follows a cross-over, double-blind, randomized and placebo control design on 10 healthy subjects

Questions about this trial

What is this clinical trial studying?

A study testing M_ML in people with Nutrition, Healthy, run by Fytexia at 1 site in Spain.

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 4 inclusion and 20 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: finished, as of the sponsor's last update on 15 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Changes in plasma concentrations of phenolic metabolites after acute ingestion of the supplement/placebo (time frame: At baseline and at 0.5 hour, 1 hour, 2 hour, 3 hour, 4 hour, 6 hour, 8 hour, 10 hour, and 24 hour after treatment intake.). 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 15 Jun 2025.
