Summary

This study employs a simulated in vitro gastrointestinal digestion model to evaluate the bioavailability of magnesium from three distinct sources: typical Polish daily dietary rations, commercial dietary supplements, and licensed medicinal products. The research aims to determine how food matrix composition and pharmaceutical formulation influence the proportion of magnesium available for absorption. Findings are expected to inform both clinical recommendations and consumer guidance regarding magnesium source selection.

UK applicability

While the study is conducted in a Polish market context, the methodological findings regarding magnesium bioavailability from different pharmaceutical forms and dietary matrices are broadly applicable to UK nutritional practice and supplement regulation, given comparable dietary patterns and EU-derived supplement standards that continue to influence UK policy.

Key measures

Bioaccessible magnesium fraction (%); magnesium content in food rations, supplements and medicinal products (mg); pharmaceutical form comparison

Outcomes reported

The study assessed the proportion of magnesium that is bioaccessible following simulated gastrointestinal digestion, comparing sources including daily food rations, dietary supplements, and pharmaceutical products available on the Polish market. It likely reported differences in bioaccessible magnesium fractions across food matrices and product types.
