NCT06990373
This cross-sectional study aims to establish reference intervals for iron biomarkers-including serum iron, ferritin, total iron-binding capacity (TIBC), and transferrin saturation (TSAT)-in healthy pregnant women during the first trimester. Additionally, the study will investigate the current prevalence of non-anemic iron deficiency (NAID) in this population. By applying strict inclusion and exclusion criteria to eliminate potential confounding factors, the study seeks to provide a reliable baseline for evaluating iron status and early detection of iron deficiency without anemia among pregnant women.

Serum ferritin is a key indicator of body iron stores and is widely used in monitoring iron status. However, oral iron doses can acutely elevate SF levels, potentially biasing assessments of iron stores during supplementation. This study aims to investigate the extent and duration of the acute iron-induced effect on serum ferritin, as well as its protein characteristics, following the administration of a single iron dose

Iron deficiency is a common problem that is often treated with the administration of oral iron. Most of the iron is not absorbed and remains in the intestine, where it influences the balance of gut bacteria. This influence is usually undesirable and should be kept as small as possible. With lower iron doses, the amount of unabsorbed iron is smaller and therefore a smaller change in the intestinal bacteria composition is to be expected.

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.

INTRODUCTION: Iron is a vital nutrient for many physiological processes including DNA production, oxygen transport and neuronal processes. However, several factors limit iron absorption including: limited bioavailability of iron (dietary or supplementation sources), can be subject to dietary iron inhibitors (e.g. calcium). Excess iron can cause cellular oxidative stress in the body. Curcumin is an active component found in turmeric, known for its anti-oxidant and anti-inflammatory properties. Co-administration of iron and curcumin may influence iron, inflammatory status and/or neurotrophic markers in the body.
