Long-term Resveratrol and Metabolism

April 1, 2019 updated by: Maastricht University Medical Center

Effects of Long-term Resveratrol Supplementation on Metabolic Health

The main objective of the study is to investigate if 6 months resveratrol supplementation can improve glucose tolerance in overweight/obese individuals. As secondary objectives we want to investigate whether resting energy metabolism, intra-hepatic lipid content, physical performance, body composition and quality of life change by 6 months resveratrol supplementation in these individuals.

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.

Ages Eligible for Study

40 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Resveratrol
resveratrol will be given for 6 months, twice daily. One pill, which contains 75 mg of resveratrol, will be provided with lunch, and the other pill of 75 mg will be provided with dinner. So in total 150 mg/day of resveratrol will be given.
Dietary supplement: resveratrol
Resveratrol will be given for 6 months, twice daily. One pill, which contains 75 mg of resveratrol, will be provided with lunch, and the other pill, also containing 75 mg will be given with dinner. So in total a dose of 150 mg/day will be given.
Other Names:
  • resVida (99% trans-resveratrol)
Placebo Comparator: Placebo
placebo will be given for 6 months, twice daily. One pill will be provided with lunch and the other pill will be provided with dinner.
Dietary supplement: placebo
A placebo will given for 6 months, twice daily. One pill will be provided with lunch, and the other pill will be provided with dinner.

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 in Glucose Tolerance
Time Frame: 2x baseline and 2x after 6 months of supplemenation
Matsuda Index calculated from double 2-hour Oral Glucose Tolerance Test (OGTT)
2x baseline and 2x after 6 months of supplemenation

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.

Once a month for a period of 6 months
Change in Physical performance
Time Frame: baseline and after 6 months of supplemenation
Physical performance will be assessed by the following tests: the Timed Chair Stand Test; the 6-minute walk test while they wear a MOX Activity Monitor; and a dynamometer (Biodex) will be used to determine isometric and isokinetic muscle strength of the extensor and flexor muscles of the knee joint
