Probiotics for Brain & Blood Sugar in Overweight Young Adults
This study tests whether taking a probiotic (a 'good bacteria' supplement) can help brain function (thinking, memory) and improve blood sugar control in overweight adults who have higher-than-normal blood sugar. If you're between 18-40, overweight, and don't have diabetes, you may be able to join.

Study of prediabetes with abnormal sugars and medicines
This study looks at adults with prediabetes—specifically abnormal fasting and/or 2-hour blood sugar tests—to see whether a treatment helps improve sugar control. You may also be compared with people who have normal blood sugar (the control group).
San Antonio, TexasAges 18–65 - NCT04199676Recruiting
Testing blood sugar after delivery for gestational diabetes
This study checks your blood sugar shortly after birth (on day 0 or day 1) to see how well glucose testing works for people who had gestational diabetes. The results may help guide follow-up care and reduce the risk of longer-term blood sugar problems.
Long Beach, CaliforniaAges 18 years+ - NCT05998772Recruiting
How sugar affects Parkinsons symptoms
This study looks at how sugar levels might change the way Parkinsons disease feels. If you have mild to moderate Parkinsons, you may be able to join and help researchers learn more about the role of food in your symptoms.
KielAges 50–80 - NCT06964620RecruitingEarly Phase 1
Sanggua tablets for early type 2 diabetes or prediabetes
This trial tests whether an herbal medicine called Sanggua tablets can help control blood sugar in people with prediabetes or mild type 2 diabetes who are not yet taking diabetes pills. If you have slightly high blood sugar but don't need medication yet, this study may help you manage it naturally.
Wuhan, HubeiAges 18–70 - NCT06912048Recruiting
How nerves signal the body in health and overweight
This study looks at how your brain sends signals to your body, comparing healthy people and those who are overweight. You'll help researchers understand differences in nerve communication.
UlmAges 18 years+ - NCT02583061Recruiting
Study of blood sugar changes during pregnancy
This study follows pregnant people to look at how blood sugar behaves during pregnancy. It may help doctors understand pregnancy-related blood sugar problems and who is at risk.
Toronto, OntarioAges 20–60 - NCT07169591Recruiting
How birth control affects blood sugar after meals
This study looks at how your body handles blood sugar after a meal if you use a specific type of birth control (certain birth control pills or IUDs) or no hormonal birth control. It may help researchers understand how hormones affect energy and sugar levels.
Hamilton, OntarioAges 18–45 - NCT06184373Recruiting
Early glucose monitoring after gestational diabetes pilot
This study tests a continuous glucose monitor (a small patch that tracks your blood sugar) for a few weeks after you give birth. It aims to see if this tool can help women who recently had gestational diabetes better understand their blood sugar levels after delivery.
Columbus, OhioAges 18–50 - NCT07470593Recruiting
Monitoring glucose to detect early pancreatic islet graft loss
This study uses a continuous glucose monitor (CGM) to watch for early signs that a transplanted pancreatic islet graft may be losing function. The goal is to catch problems sooner and help keep the transplant working well.
StrasbourgAges 18 years+ - NCT04234724Recruiting
Study of how ANGPTL3 gene variants affect body functions
This study looks at how different ANGPTL3 gene versions may change normal body measurements (such as blood and metabolism). It may help researchers understand why these genetic differences affect health, especially related to fats (lipids) in the body.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06684106Recruiting
Can a liver medicine protect your blood sugar while on statins?
This study tests if a medicine called ursodeoxycholic acid can help prevent blood sugar rises that statins sometimes cause. It is for people with high cholesterol who have not yet taken a statin, to see if adding this medicine keeps their blood sugar healthy.
Xi'an, ShaanxiAges 18–75 - NCT07603739Recruiting
Testing Almonds to Help Control Blood Sugar Levels
This study tests whether eating almonds before meals can help control blood sugar in adults with slightly elevated glucose levels. Researchers want to see if this simple dietary change could help prevent or delay type 2 diabetes.
Baton Rouge, LouisianaAges 25–50 - NCT05777330Recruiting
Monitoring blood sugar swings to predict type 1 diabetes
This study watches blood sugar changes over time in people who do not yet have diabetes but have test results that suggest risk for type 1 diabetes. The goal is to see whether “blood sugar variability” can predict when high or low blood sugar may happen, even before symptoms.
Liège, LiègeAges 5–39 - NCT04731272RecruitingPhase 2
Weekly GLP-1 medicine for blood sugar issues in adults with CF
This Phase 2 trial tests a weekly GLP-1 medicine (dulaglutide) to improve blood sugar control in adults with cystic fibrosis (CF) who have trouble managing glucose. It may help people with CF-related prediabetes or diabetes by improving how their body handles sugar.
Aurora, ColoradoAges 18 years+ - NCT07410637Recruiting
Thyroid hormones and energy in graves' or thyroid cancer
This trial studies how thyroid hormone levels affect your body's use of sugar and energy. It may help people newly diagnosed with Graves' disease or thyroid cancer understand their metabolism better.
Ulm, Baden-WurttembergAges Any age - NCT07233434Recruiting
Diabetes screening with sugar drink test in Guadeloupe
This study checks if a special sugar-drink test can find type 2 diabetes in people whose fasting blood sugar is normal but whose HbA1c is slightly high. It is for adults 18–64 of African or Indian descent with certain risk factors.
Pointe-à-Pitre, GuadeloupeAges 18–65 - NCT07020741Recruiting
Stable isotope study in adults with obesity
This study uses a special test (stable isotopes) to learn about how adults with obesity process food and energy. It may help researchers understand weight and metabolism better.
Urbana, IllinoisAges 19–59 - NCT06693934Recruiting
Prevention program for young adults at risk of diabetes
This trial offers a prevention program for young adults aged 18 to 44 who have at least one risk factor for diabetes but do not already have diabetes. The program aims to help prevent or delay the onset of diabetes.
Hong KongAges 18–44 - NCT06097065Recruiting
Finding diabetes and prediabetes markers in blood and urine
This study looks at leftover blood and urine samples to find new markers that could help detect prediabetes and diabetes earlier. It may lead to better testing and management.
Guangzhou, GuangdongAges Any age - NCT06396871Recruiting
Blood cell study in metabolic diseases
This study looks at blood cells and factors in people with metabolic diseases like fatty liver, prediabetes, or type 2 diabetes. It aims to better understand these conditions by comparing them with healthy volunteers.

Common questions
- Are there clinical trials for glucose tolerance?
- Yes. Clin2 currently lists 45 recruiting glucose tolerance 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 glucose tolerance 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 glucose tolerance 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.
