A Food-Derived Dietary Supplement Containing a Low Dose of Iron Improved Markers of Iron Status Among Nonanemic Iron-Deficient Women.
Trial report in Journal of the American College of Nutrition. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02683369 (Effects of a Commercially-available, Low-dose Iron Supplement), which is not on this map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
objectiveIron deficiency is the most common nutrient deficiency in the world. While deficiency can often be resolved through dietary supplementation with iron, adverse events are common and frequently preclude compliance. The objective of this study was to determine whether a food-derived dietary supplement containing a low dose of iron and nutrients that increase iron absorption could resolve iron deficiency with fewer adverse events than reported at higher doses.
methodsA pilot clinical trial (NCT02683369) was conducted among premenopausal women with nonanemic iron deficiency that was verified by blood screening. Participants consumed a dietary supplement (Blood Builder®/Iron Response®) once daily for 8 weeks containing 26 mg of iron, vitamin C, folate, and other food-derived nutrients. Primary outcomes were markers of iron status (serum ferritin, hemoglobin, soluble transferrin receptor, total body iron stores) and secondary outcomes were self-reported fatigue and energy. All outcomes were assessed at baseline and 8 weeks. Adverse events were monitored with questionnaires, daily diaries, and contact with a physician. Dependent samples t test and Wilcoxon signed-rank test were used to analyze outcomes.
resultsTwenty-three participants enrolled in the study. Iron deficiency was resolved in the sample (mean serum ferritin: baseline = 13.9 μg/L, 8 weeks = 21.1 μg/L, p < 0.001). All other markers of iron status, fatigue, and energy also improved during the study (p < 0.04). No adverse events were reported.
conclusionsWhile larger and controlled studies are needed to confirm these findings, a food-derived dietary supplement with a low dose of iron and absorption-enhancing nutrients resolved iron deficiency and improved all other markers of iron status without any adverse events.
