The Effects of Nicotinamide Riboside Supplementation on Brain NAD+/NADH Ratio and Bioenergetics

March 4, 2024 updated by: Dost Ongur, Mclean Hospital

The Effects of Nicotinamide Riboside Supplementation on Nicotinamide Adenine Dinucleotide (NAD+/NADH) Ratio and Bioenergetics

The primary aim of this study is to investigate the effects of exogenously administered nicotinamide riboside (NR) on brain NAD+/NADH ratio and bioenergetics functions in healthy individuals using phosphorus magnetic resonance spectroscopy (31P MRS) imaging.

The secondary aims are to investigate the change in brain PCr/ATP and creatine kinase enzyme rate after NR use. In addition, NAD+/NADH ratio, PCr/ATP and CK enzyme rate will be measured in the calf muscle, as secondary outcome measures.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline to the End of Treatment in Brain NAD+/NADH Ratio
Time Frame: Baseline and after 15 days of supplement use

Change from baseline to the end of treatment in brain NAD+/NADH ratio as measured by in vivo 31P magnetic resonance spectroscopy

The NAD+/NADH ratio is calculated by first quantifying NAD+ and NADH separately in the data and then obtaining a simple ratio. There is a normative NAD+/NADH ratio range in healthy brain and deviations from this level in either direction can be a sign of pathology.
Baseline and after 15 days of supplement use

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
