Racial/Ethnic in Calcium and Sodium Metabolism
NCT05537857 · View on ClinicalTrials.gov ↗
Study Summary
The increased interest in personalized nutrition has arisen because scientists are beginning to understand subgroup differences in response to the environment including diet. Some suggest that dietary guidance which promotes milk is racially and ethnically insensitive because of higher prevalence of lactose intolerance/maldigestion in non-white groups. Preliminary evidence in Black and White adolescent girls shows that Blacks retain more calcium and excrete more sodium than white girls on a high sodium diet making Whites more vulnerable to osteoporosis and Blacks more vulnerable to hypertension on high salt diets. Adequate dietary calcium is protective for both groups. This project will compare calcium absorption and calcium and sodium excretion from lactose-free milk as part of a controlled diet on higher (usual Western diet) and lower (recommended) salt intakes in Black, White, Hispanic, and Asian adults.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT05537857
The ClinicalTrials.gov registry entry for NCT05537857 describes a study currently listed as active not 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 66 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is San Diego State University, which has 201 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 1 intervention — of which High dietary salt 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: NCT05537857 reports 1 study location spanning 1 distinct geographic area — top geographies include California. 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.
