Can a New NAD+ Supplement Boost Energy at the Cellular Level?
This study tests a daily supplement called Qualia NAD+ to see if it increases energy-related molecules inside your cells. You'll take the supplement at home, avoid other B3 vitamins, and use a simple finger-stick test to measure your levels.
Carlsbad, CaliforniaAges 40–65 - NCT06627868Recruiting
NAD+ metabolism in human brown fat
This study explores how the body's natural substance NAD+ works in brown fat, a type of fat that burns calories. It may help researchers understand metabolism and find new ways to treat obesity.
TurkuAges 30–65 - NCT06919328Recruiting
Testing a new form of Niagen for energy and fatigue
This trial tests how well a new injectable form of Niagen (a supplement that may boost cellular energy) is absorbed and tolerated compared to NAD+. It may help if you are between 40 and 65, live near the study site, and feel unusually tired.
Huntsville, AlabamaAges 40–65 - NCT07203131Recruiting
NAD+ metabolism and kidney risk in intensive care
This trial tests whether changes in NAD+ (a natural molecule in your cells) affect kidney health during intensive care. It aims to predict and prevent acute kidney injury in patients at high risk.
TrappesAges 18 years+ - NCT07703137Enrolling by invitation
NAD Supplement for Parkinson's Disease Study
This study tests whether a supplement called NAD (a natural substance that helps cells produce energy) can improve symptoms in people with Parkinson's disease. You would take the supplement daily for several weeks, and researchers will check your movement, thinking, and overall well-being.
Oklahoma City, OklahomaAges 55–85 - NCT05483465RecruitingPhase 4
NAD supplement trial for brain blood vessel health in aging
This trial studies whether taking an NAD supplement can support brain blood vessel health as people age. Participants will be tested for brain and health changes and may help researchers understand how to keep the brain’s blood vessels healthier over time.
Oklahoma City, OklahomaAges 60–85 - NCT07727161Recruiting
3D printing to plan spine fracture surgery
This trial uses 3D-printed models to help surgeons plan operations for broken bones in the mid or lower back. It aims to make surgery more precise and safer.
Ústí nad LabemAges Any age - NCT04750616RecruitingPhase 2
NAD+ for heart injury prevention around non-emergency surgery
This Phase 2 trial studies whether adding NAD+ can reduce heart muscle injury around scheduled heart surgery. It may help protect the heart (and possibly kidneys) in people considered higher risk for complications.
San Francisco, CaliforniaAges 18 years+ - NCT05759468RecruitingPhase 2
Add NAD to help protect kidneys in diabetes
This Phase 2 study tests whether adding NAD can improve kidney health in people with diabetes-related kidney disease. It is designed for people with certain urine lab results showing kidney stress, while keeping blood sugar and safety limits within range.
Boston, MassachusettsAges 30 years+ - NCT06032923RecruitingPhase 1/Phase 2
Does vitamin B3 boost help lupus symptoms?
This study tests whether a form of vitamin B3, called nicotinamide riboside, can improve immune function and reduce inflammation in women with mild to moderate lupus. It may help understand if boosting NAD+ levels offers a new way to manage the disease.
Bethesda, MarylandAges 18–120 - NCT06162013RecruitingPhase 2
NAD supplement trial for atypical parkinsonism
This trial tests whether a supplement called nicotinamide riboside (NR) can help people with rare forms of parkinsonism (PSP, MSA, or CBS). It is a double-blind study, meaning neither you nor the doctors will know if you are getting the real supplement or a placebo.
Oslo, OsloAges 30–85 - NCT06776510RecruitingPhase 1/Phase 2
NAD for immune thrombocytopenia study
This trial tests if a substance called NAD can help adults with immune thrombocytopenia (ITP) whose platelet levels stay low even after standard treatments. ITP is a condition where the immune system attacks platelets, causing easy bruising and bleeding. The study aims to see if NAD can safely raise platelet counts.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT06853743RecruitingPhase 2
Study of nicotinamide riboside for Huntington's disease
This trial tests if a vitamin B3-like supplement, nicotinamide riboside, can help people with early to mid-stage Huntington's disease. You will be randomly assigned to take the supplement or a placebo to see if it slows the disease.
OsloAges 18–80 - NCT06882096RecruitingPhase 1
How the body processes NAD+ boosters in healthy adults
This study looks at how the body uses NAD+ precursors (nutrients that help cells produce energy) after taking them by mouth. Healthy volunteers will help researchers understand how these supplements are processed, which may guide future treatments for aging and disease.
Boston, MassachusettsAges 18 years+ - NCT06991712RecruitingPhase 2
NAD supplements for nerve health in glaucoma
This trial tests whether NAD precursor supplements can improve nerve health and vision in people with glaucoma. If you have glaucoma with mild to moderate vision loss, this study may help understand if these supplements could protect your optic nerve.
Wong Chuk HangAges 18 years+ - NCT07127510Recruiting
Brain NAD in Alzheimer's disease study
This study tests whether a natural substance called NAD can improve brain health in people with early Alzheimer's. You may be eligible if you have a firm Alzheimer's diagnosis, are between 65 and 80, and can walk and talk without help.
Boca Raton, FloridaAges 65–80 - NCT07361198Recruiting
Knee artery embolization for arthritis pain
This trial tests a minimally invasive procedure to block small blood vessels in the knee, which may reduce pain from osteoarthritis. It's for people with ongoing knee pain even after standard treatments like medication or physical therapy.
Ústí nad LabemAges 40–80 - NCT07516834Recruiting
Spine Surgery Recovery: Open vs. Minimally Invasive Approaches
This study compares how people recover their normal walking patterns after surgery for mid-to-lower spine fractures. Researchers will measure your gait (how you walk) and muscle activity to see if the type of surgery affects how quickly you heal.
Ústí nad Labem, Ústí nad Labem RegionAges 20–75 - NCT07563322Recruiting
Nicotinamide Riboside for Combined Pulmonary Hypertension
This study tests whether nicotinamide riboside (a B-vitamin supplement) can help people with combined pulmonary hypertension—a condition where blood pressure in the lungs is too high. The researchers want to understand how this supplement affects the body's energy metabolism and whether it might reduce symptoms and improve heart function.

Common questions
- Are there clinical trials for nad?
- Yes. Clin2 currently lists 19 recruiting nad 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 nad 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 nad 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.
