Trial summary

The prevalence of age-related chronic diseases (like obesity, type 2 diabetes and cardiovascular diseases) is mounting worldwide, reaching pandemic proportions. These age-related chronic diseases are associated with diminished skeletal muscle mitochondrial function in humans. Read more about this study

About this study

Official title: Boosting the NAD+ Levels in Older Individuals Via Nicotinamide Riboside Supplementation and Exercise Training to Promote Metabolic Health

The prevalence of age-related chronic diseases (like obesity, type 2 diabetes and cardiovascular diseases) is mounting worldwide, reaching pandemic proportions. These age-related chronic diseases are associated with diminished skeletal muscle mitochondrial function in humans. Nicotinamide adenosine dinucleotide (NAD) is a coenzyme that regulates mitochondrial function, therefore, plays an important role in energy metabolism. Importantly, it has been shown that high cellular NAD+ levels as well as a high NAD+/NADH ratio promote metabolic and mitochondrial health. In contrast, NAD+ bioavailability declines upon aging in humans as well as in animal models of metabolic disorders and type 2 diabetes. These findings fuel the notion of boosting the NAD+ bioavailability in order to improve metabolic disturbances and mitochondrial dysfunction in aged individuals. Supplementation with nicotinamide riboside (NR), a naturally occurring form of vitamin B3, boosts cellular NAD+ levels. However, in contrast to animal studies, NR supplementation in humans has so far been unsuccessful in improving skeletal muscle mitochondrial function, exercise capacity or insulin sensitivity. Interestingly, Recently, it has been suggested that metabolic conditions where NAD+ levels become limited, is needed for NR supplementation to exert beneficial health effects. This metabolic condition could be achieved by exercise. However, studies combining NR and exercise are lacking, and that is why we will perform the present study.

Questions about this trial

What is this clinical trial studying?

A study testing Nicotinamide Riboside (NR) in people with Healthy Aging and Lifestyle-related Condition, run by Finis Terrae University at 1 site in Chile.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 11 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Chile. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Rodrigo Mancilla, PhD (+56953676588, rmancilla@uft.cl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Skeletal muscle mitochondrial respiratory capacity (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jul 2025.
