About this study
The purpose of this study is to assess the amino acid oxidation dose-response relationship of ingested whole-food protein in healthy adults. In a randomized, crossover design, 20 young, healthy adult males and females aged 18-35 years, will consume a dinner consisting of 0.32, 0.74, and 1.32 g protein･kg BM-1 (corresponding to 1, 2, and 4 minced beef patties, respectively) during 3 separate experimental trials.The main study endpoint is the amino acid oxidation of ingested protein over a 24-h period.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Food proteinsDietary supplement
Dinner meal consisting of minced beef protein.
| Study group | Role | What they receive |
|---|---|---|
| Dinner consisting of 0.32 g protein･kg BM-1 | Experimental | Not described Receives: Dietary Supplement: Food proteins |
| Dinner consisting of 0.74 g protein･kg BM-1 | Experimental | Not described Receives: Dietary Supplement: Food proteins |
| Dinner consisting of 1.32 g protein･kg BM-1 | Experimental | Not described Receives: Dietary Supplement: Food proteins |
What is being measured
The primary outcome is the main question the study is designed to answer.
Amino acid oxidation of ingested protein
Amino acid oxidation; compared between interventions to determine the dose-response relationship of amino acid oxidation to ingested whole-food protein.
Measured: Over the 24 hour timeframe following protein ingestion
Secondary outcomes (1)
Plasma amino acid response of ingested protein
Plasma amino acid response; comparison between interventions to determine the plasma amino acid response to different amounts of ingested whole-food protein.
Measured: Over the 24 hour timeframe following protein ingestion

Questions about this trial
What is this clinical trial studying?
A study testing Food proteins in people with Protein Metabolism, run by Maastricht University Medical Center at 1 site in Netherlands.
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 9 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: looking for participants now, as of the sponsor's last update on 23 Apr 2026. 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 Netherlands. 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?
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?
Contact Julia M Malowany, MSc (+31 43 388 1617, julia.malowany@maastrichtuniversity.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Amino acid oxidation of ingested protein (time frame: Over the 24 hour timeframe following protein ingestion). 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 23 Apr 2026.
