Improving the Iron Status of Athletes With Pre-, Pro- and Synbiotics
NCT06021171 · View on ClinicalTrials.gov ↗
Study Summary
Iron deficiency (ID) is the most common micronutrient deficiency worldwide, and poor iron bioavailability is a major cause. While 30% of female athletes are affected by ID, and its consequences are highly relevant to athletic performance, ID affects women and children around the world with consequences just as relevant, if not more so (e.g. school performance, work capacity and thus wage earning). With poor iron absorption being a cause of ID in active women, it is especially important to discover simple ways to improve iron (Fe) uptake. While some studies have suggested that consumption of prebiotic fiber may improve Fe absorption in animal models, there have been few studies examining the effects of synbiotic supplementation (consumption of both a prebiotic and probiotic that work together) on Fe uptake in adult females (athletes and non-athletes). A recent pilot study demonstrated a substantial improvement in Fe uptake in female athletes after 4 and 8 weeks of synbiotic supplementation compared to placebo during Fe repletion with a low dose of ferrous sulfate (FeSO4). If synbiotic supplementation can improve the Fe bioavailability of FeSO4 (which is \~30%) in ID women during repletion of Fe status, it could possibly improve the Fe bioavailability of non-heme Fe sources, as well as mixed meals. Research Question: What is the effect of synbiotic supplementation (a supplement containing a prebiotic + a probiotic), compared to prebiotic supplementation or a placebo, on Fe uptake and the gut microbiome in ID athletes during low-dose Fe repletion? Hypothesis: In the proposed study, we hypothesize that synbiotic supplementation along with Fe repletion with a low dose of FeSO4 will have greatest impact on athletes' Fe uptake due to alterations in the microbiome, which will be assessed.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06021171
The ClinicalTrials.gov registry entry for NCT06021171 describes a study currently listed as completed. 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 10 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is King's College, which has 1 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Iron Deficiency Anemia appearing as the primary indexed condition, and to 3 interventions — of which Maltodextrin 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: NCT06021171 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. 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.
