In Vitro Evaluation of Bioavailability of Mg from Daily Food Rations, Dietary Supplements and Medicinal Products from the Polish Market.
Article in Nutrients, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNutrients consumed with food undergo the digestion process, and only some of them are absorbed from the gastrointestinal tract (GI) and enter the bloodstream. Minerals, including Mg, are crucial for maintaining the body's homeostasis, but their beneficial effect depends on their bioavailability, i.e., the part that can be absorbed and used by the body. The bioavailability of nutrients taken in pharmaceutical form is usually higher than the same nutrients contained in food, because their absorption requires prior release from the food matrix.
objectivesThe main objective of the conducted research was to assess the bioavailability of Mg from dietary supplements and medicinal products, considering the influence of the type of diet and pharmaceutical form on bioavailability.
methodsThe experiments were conducted using a previously developed and optimized two-stage in vitro digestion model using cellulose dialysis tubes and ICP-OES method. The influence of three types of diets-standard, basic and high-residue-on the bioavailability of Mg was evaluated.
resultsThe bioavailability of Mg from the studied diets was within the range of 48.74-52.51%.
conclusionsIn the models studied, it was observed that the factors influencing bioavailability were the nutritional composition of the diets and the chemical form of Mg.
