About this study

Official title: The Efficacy of Quercetin Supplementation on Bone Turnover Markers, Inflammatory Markers, Body Composition, and Physical Function in Post-Menopausal Women

Quercetin is a plant-based flavonoid that is naturally found in many fruits and vegetables, and is considered to be a potent antioxidant with several expected health benefits such as anti-inflammatory effects and bone-conserving properties. Participants will supplement with either Quercetin, or placebo, for 90-days with pre- and post-testing visits.

Read the detailed description

Quercetin is a plant-based flavonoid that is naturally found in many fruits and vegetables such as onions, apples, berries, green tea, and red wine and is currently an FDA approved supplement. Quercetin is considered to be a potent antioxidant with several expected health benefits. Both in vivo and in vitro studies have demonstrated that quercetin acts as a potent natural osteogenic agent with benefits that include anti-inflammatory effects and bone-conserving properties. Quercetin is suggested to protect against bone loss by inhibiting bone resorption and stimulating bone formation which is indicated by an increase in bone mineral density and bone formation markers such as osteocalcin.

The purpose of this study is to investigate the effects of quercetin supplementation on bone, specifically on bone turnover markers, in postmenopausal women. The interplay between cytokines (i.e., IL-6, CRP, and TNF-alpha) and bone turnover markers was also considered.

In a double-blind, placebo-controlled fashion, we aimed to recruit 50, healthy, postmenopausal women between the ages of 45-75 years to participate in a 90-day supplement trial. Participants will be randomly assigned to one of two supplement groups: 1) quercetin 500 mg, once per day, or 2) placebo (methyl cellulose E4M) 500 mg, once per day for 90-days.

Participants will be asked to visit the laboratory (KSU Human Performance Laboratory) on 2 separate occasions for pre- and post-testing visits consisting of body composition measurements and blood draws by a CITI approved/IRB approved research team member trained in phlebotomy under the supervision of Dr. VanDusseldorp.

Questions about this trial

What is this clinical trial studying?

A study testing Quercetin (500 mg) in people with Osteoporosis, Postmenopausal, run by Kennesaw State University at 1 site in United States.

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 2 inclusion and 20 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: finished, as of the sponsor's last update on 12 May 2022. 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 United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Osteocalcin ng/mL (time frame: 90-days). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05371340, which also lists 1 linked publication.

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 12 May 2022.
