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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether taking collagen peptides daily for 6 months can help slow aging at the cellular level in adults aged 50-70 who are overweight and not very active. Researchers will measure telomere length (a marker of cellular age), inflammation, and body composition. 125 participants will be randomly assigned to take either collagen or a placebo, with blood tests and physical assessments at the start, 3 months, and 6 months.

What this could mean

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

Active substance
collagen peptides
What this could lead to
If it works, this could point toward a simple dietary supplement that supports healthier aging at the cellular level.
What could go wrong
This is an early-stage, small study (125 people) testing a supplement, not a drug. Results may show no effect on telomeres or aging markers, and any benefits may not apply to the general population.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 125 people

The number the study aims to enrol. It can still change while the study runs.

Started

Apr 2026

Expected to finish

Aug 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

50 to 70 years

Sex

Accepted

You do not need to have the condition being studied to take part.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 50-70 years; both male and female participants are eligible * Body mass index (BMI) 25-30 kg/m² * Low to moderate physical activity: not meeting current WHO recommendations (\<150 minutes/week) or ≤2 sessions/week structured training * Able to live independently and mobile in daily life * No regular resistance training within the past 6 months * Provision of written informed consent Exclusion Criteria: * Diagnosed chronic diseases relevant to the immune system, metabolism, or cellular aging (e.g., diabetes mellitus, cancer, cardiovascular, rheumatologic diseases) * Use of immunomodulatory, systemic anti-inflammatory, or hormonal medications (e.g., corticosteroids, immunosuppressants) * Acute infections or surgeries within the last 3 months * Regular use of supplements known to affect oxidative stress or cellular aging (e.g., high-dose antioxidants, CoQ10, omega-3 fatty acids, high-dose vitamin D) * Participation in another clinical study within the last 3 months * Vegetarian or vegan diet (product contains animal-derived collagen)
