How to Find Doctor-Led NAD+ and Longevity Clinical Trials in 2026

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme critical for cellular energy, DNA repair and overall metabolic health. As we age, NAD+ levels naturally decline, spurring interest in NAD+ supplementation and therapies to support healthy aging and longevity. Doctor-led NAD+ clinical trials are the gold standard for testing whether these therapies are both safe and effective. In this guide, you'll learn where and how to find reputable, doctor-led NAD+ and longevity clinical trials in 2026—without getting overwhelmed.

Why Choose a Doctor-Led Clinical Trial?

Clinical trials led by medical professionals offer several advantages:

• Rigorous oversight
  Institutional Review Boards (IRBs) and medical ethics committees closely monitor trial design, execution and patient safety.
• Standardized protocols
  Participants follow clearly defined procedures for dosing, monitoring and follow-up.
• Qualified medical staff
  Doctors, nurses and clinical coordinators are on hand to address side effects, answer questions and manage emergencies.
• Transparent reporting
  Results are published in peer-reviewed journals or on recognized registries, ensuring reliable data.

Doctor-led trials are the cornerstone of evidence-based medicine. Unlike anecdotal reports or unregulated clinics, these studies systematically collect safety and efficacy data.

Where to Search for NAD+ and Longevity Clinical Trials

Finding the right trial takes some research. Below are the most trusted sources:

1. ClinicalTrials.gov
   The largest public registry of privately and publicly funded trials worldwide.

   • Use keywords like "NAD+," "nicotinamide adenine dinucleotide," and "longevity."
   • Filter by "Interventional Studies," "Recruiting," and "Location" to narrow your search.

2. NIH Research & Training
   The National Institutes of Health often sponsors aging and metabolic health trials.

   • Visit the NIH website's Clinical Research Trials and You section.
   • Search for "NAD+" within aging or metabolic disorder categories.

3. University Medical Centers
   Leading research hospitals (e.g., Mayo Clinic, Cleveland Clinic, UCSF) regularly run anti-aging and metabolic trials.

   • Check the clinical research pages of these institutions.
   • Subscribe to newsletters or clinical trial alerts.

4. Professional Societies
   Organizations like the American Society for Nutrition or the Gerontological Society of America may list member-led trials.

   • Explore their websites for conference abstracts and trial listings.

5. Longevity Research Institutes
   Private research institutes (e.g., Buck Institute, SENS Research Foundation) sometimes run open-enrollment studies.

   • Review their "Get Involved" or "Clinical Trials" pages for active opportunities.

6. Pharmaceutical and Biotech Companies
   Companies developing NAD+ precursors (NR, NMN) often recruit participants directly.

   • Look for press releases or "Careers & Trials" sections on their sites.

Evaluating Trial Credibility

Not all clinical trials are created equal. To ensure you're joining a high-quality, doctor-led study, look for:

• Registration on reputable platforms
  Confirm the trial is listed on ClinicalTrials.gov, the EU Clinical Trials Register, or an equivalent government database.
• IRB or ethics approval
  The listing should mention IRB review or ethics committee oversight.
• Principal investigator credentials
  Check the doctor's or researcher's name and affiliation (e.g., MD or PhD at a recognized university).
• Clear inclusion/exclusion criteria
  Legitimate trials state age range, health conditions, medication restrictions and other eligibility requirements.
• Detailed study protocol
  You should be able to access a summary of the trial design—dosing schedule, duration, monitoring visits.
• Contact information
  A real phone number or institutional email address for the trial coordinator should be provided.
• Safety monitoring
  Trials must include regular health assessments, lab tests and adverse event reporting.

If any of these elements are missing or vague, proceed with caution.

Steps to Join a NAD+ Clinical Trial

1. Clarify your goals and health status

   • Decide whether you want to focus on energy metabolism, cognitive function, physical performance or general longevity.
   • Gather your medical records, including recent lab results and physician summaries.

2. Search targeted databases

   • Start with ClinicalTrials.gov using precise keywords ("NAD+," "NMN," "NR," "longevity").
   • Bookmark promising trials and note recruitment status and locations.

3. Review eligibility

   • Read through inclusion and exclusion criteria carefully.
   • Be honest about medical history, current medications and lifestyle factors.

4. Contact trial coordinators

   • Send a brief email or phone inquiry proposing your interest.
   • Ask for a copy of the study protocol, details on visits, compensation (if any) and travel requirements.

5. Discuss with your primary care provider

   • Share trial details and protocol with your doctor to ensure safety.
   • Ask whether your doctor can oversee any outside-of-protocol testing you wish to continue.

6. Complete screening assessments

   • Attend baseline evaluations (blood work, ECG, functional tests).
   • Some trials may require a short run-in period on placebo or no supplement before randomization.

7. Enroll and follow the protocol

   • Attend all scheduled visits, lab draws and surveys.
   • Report any side effects immediately—trials typically have a 24/7 hotline.

Maximizing Your Experience

• Keep a journal of symptoms, energy levels and any side effects.
• Stay in regular contact with the study team.
• Adhere strictly to dosing schedules, visit windows and lab requirements.
• Maintain open communication with your personal doctor.

Even if you don't meet the eligibility for one trial, ask coordinators about upcoming studies. Many sponsors maintain waitlists and new trials launch throughout the year.
