About this study

Official title: A Double Blind, Randomized, Cross-over, Comparative Bioavailability Study of 3 Different Forms of Folate in Healthy Subjects

The aim of this prospective interventional study is to compare the bioavailability of the 6S-5-methyltetrahydrofolate (5-MTHF) glucosamine salt versus two other forms of 5- MTHF calcium salts by measuring serum 5-MTHF responses after a single ingestion of equivalent doses of the three folate forms in humans.

The hypothesis of this study is that the test products 5-MTHF glucosamine and calcium salts have equivalent bioavailabilities in serum 5-MTHF as measured by the area under the curve over a period of 24 hours (AUC0-24h) after consumption of a single dose of 5-MTHF (400μg).

Questions about this trial

What is this clinical trial studying?

A study testing 5-MTHF glucosamine salt, 5-MTHF calcium salt 1 and 5-MTHF calcium salt 2 in people with Healthy, run by Lesaffre International at 1 site in France.

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 8 inclusion and 26 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: stopped early, as of the sponsor's last update on 5 Jan 2024. 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 France. 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. 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 was stopped early (reason given: Analytic issue). Results are not available in the source record.

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?

Area under the curve (AUC) 0-24 hours of serum 5-MTHF concentrations (time frame: 0-24 hours). 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 5 Jan 2024.
