NCT ID NCT07243730

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study aims to see if yogurt or milk provides essential amino acids (the building blocks of protein) more quickly after eating. Thirty healthy adults will consume either yogurt or milk on two separate visits, and blood samples will be taken over several hours to measure amino acid levels. The results could help people choose the best dairy option for protein absorption.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
full fat yogurt and full fat pasteurized milk
What this could lead to
If it works, this could help understand which dairy product provides better protein absorption, potentially guiding dietary recommendations.
What could go wrong
This is a small, early-stage study in healthy volunteers, so results may not apply to people with health conditions. It measures short-term blood levels, not long-term health outcomes.
