Recruiting studies
- NCT05562128Recruiting

This study looks at how thinking and memory work in healthy adults and compares them to people with certain health conditions. As part of the control group, you will help researchers understand normal cognitive function.
Gdansk, Pomeranian VoivodeshipAges 18 years+ - NCT06837246Recruiting
Nutritional supplement study for cognitive health in adults
This study tests whether a nutritional supplement taken as 3 capsules daily for 12 weeks can improve cognitive function. It is designed for generally healthy adults who do not have certain medical conditions or take certain medications.
Addison, IllinoisAges 25–65 - NCT05758961Recruiting
Study of gut bacteria in adults living in France

BobignyAges 18 years+ - NCT05951764Recruiting
Checking risk prediction for heart and brain conditions
This study builds or tests computer models that predict risk for heart (cardiovascular) and thinking/memory (neurocognitive) problems using information from people in the general population. It may help improve early detection and planning for care.
ParisAges 45 years+ - NCT04834518Recruiting
Screening children for early signs of type 1 diabetes
This study checks for specific blood markers (“islet autoantibodies”) to find children who may be at risk for developing type 1 diabetes later, before symptoms start. It’s mainly for children who have no known diabetes yet.
BeershebaAges 9 months–5 years - NCT07524985Recruiting
Cannabis Use Study: Understanding Effects in Daily Users

Testing heart risk assessment using MRI T1 mapping
This study checks whether an MRI heart scan measure called “T1 mapping” can improve how doctors estimate heart disease risk in everyday people. You may join if you’re an adult and can have a contrast-enhanced heart MRI safely.
Frankfurt am Main, HesseAges 18 years+ - NCT04477928Recruiting
Checking type 1 diabetes risk using routine child care
This study estimates the chance of developing type 1 diabetes in children by using information gathered during regular well-child visits. It may help identify children who could benefit from earlier monitoring.
Bemidji, MinnesotaAges birth–17 years - NCT04843371Recruiting
Using wearable data to predict heart pump strength
This trial tests whether a wearable device (Biostrap) can help predict how strongly your heart pumps, using echocardiogram (heart ultrasound) results. It may help doctors better estimate heart function from simpler measurements.
New Orleans, LouisianaAges 18–120 - NCT05328856Recruiting
Vital shower study to improve well-being and body regulation
This trial studies whether a special “vital shower” can improve quality of life, immune-related measures, heart/blood-pressure regulation, and overall well-being. You may be a fit if you’re generally healthy enough and can safely use the shower setup during the study.
Berlin, State of BerlinAges 18–70 - NCT06017687Recruiting
Test a smartphone app for blood pressure checks

Truckee, CaliforniaAges 18 years+ - NCT06166810Recruiting
Healthy gut bacteria and high fiber diet study
This study looks at gut bacteria in healthy people who eat a high fiber diet. If you are between 20 and 50, eat at least 5 fruits and vegetables a day, and meet other health criteria, you may be able to help researchers learn how diet affects good gut bacteria.

Common questions
- Are there clinical trials for general population?
- Yes. Clin2 currently lists 35 recruiting general population studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a general population trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a general population trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
