Sodium vs Potassium Education to Improve Vascular Health
NCT07221448 · View on ClinicalTrials.gov ↗
Study Summary
The goal of this clinical trial is to determine if a self-selected high potassium diet is easier to achieve and more effective at improving vascular health than a low sodium diet in generally healthy young adults who typically consume more than the recommended amount of sodium. The main questions it aims to answer are: 1. Is it easier for young adults to increase their potassium intake, rather than reduce their sodium intake? 2. Is a self-selected high potassium diet better at improving vascular health compared to a self-selected low sodium diet? Researchers will compare the effectiveness of an education-based intervention centered only on increasing dietary potassium intake against an education-based intervention centered only on reducing dietary sodium intake. Participants will be randomly assigned to receive comprehensive dietary education on adopting either a high-potassium diet or a low-sodium diet. Education will be delivered in four weekly one-on-one sessions. Following the four-week education period, participants will be encouraged to change their diet based on what they have learned. Measures of dietary compliance (urine samples and diet records) and cardiovascular health (blood pressure, endothelial function) will be assessed at two, four, and six months post-education.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT07221448
The ClinicalTrials.gov registry entry for NCT07221448 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 32 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Florida State University, which has 291 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Healthy appearing as the primary indexed condition, and to 2 interventions — of which High potassium dietary education/counseling 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: NCT07221448 reports 1 study location spanning 1 distinct geographic area — top geographies include Florida. 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.
