Effects of Freeze-dried Grape Powder on Immune Profiles in Healthy Aging Adults
NCT07079982 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to investigate the effects of consuming grape powder on immune profiles in healthy middle- and older-aged individuals. Specifically, the investigators are interested in evaluating the potential effects of grapes in influencing markers of immune function, inflammation, and metabolism that are known to change with aging. Grapes contain several nutrients and antioxidant polyphenols such as resveratrol, quercetin, vitamin K and fiber, which are known to promote heart and immune health. However, the effects of grapes on altering immune profiles within the context of aging is not well understood. Therefore, this study will explore how daily grape consumption impacts certain markers of immunity in healthy middle- and older-aged adults. The main study procedures include consumption of a freeze-dried grape powder and control powder (which tastes the same but has none of the grape compounds that are being studied) mixed with water as a beverage on a daily basis for 4 weeks each. The investigators will additionally ask that participants avoid eating grapes and certain other antioxidant/grape-related foods and beverages throughout the 13-week study. Participants will additionally be asked to complete surveys about their diet, physical activity, and medical history, as well as provide blood samples and body weight measures throughout the course of the study. Participation in the study is expected to last about 6.25 hours over the course of 13 weeks and will include 7 visits.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT07079982
The ClinicalTrials.gov registry entry for NCT07079982 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 28 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Connecticut, which has 43 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Inflammation appearing as the primary indexed condition, and to 2 interventions — of which Freeze-dried whole grape powder is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT07079982 reports 1 study location spanning 1 distinct geographic area — top geographies include Connecticut. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
