Dietary Supplements in Public Health: Benefits, Risks, and Emerging Gel/Hydrogel Delivery Systems

Year: 2026

Type: article

Abstract: In recent years, the global use of dietary supplements has surged, largely due to their appeal as tools for improving well-being and preventing disease. While these products may offer clear advantages-such as addressing micronutrient shortages and enhancing physical or mental performance-they also carry significant risks, including toxicity, potential drug interactions, and limited clinical validation. This paper explores the current body of scientific literature on dietary supplements, offering a nuanced analysis of their advantages and drawbacks, particularly in general and military populations. Drawing upon peer-reviewed studies, regulatory documents, and expert guidelines, the review outlines key safety considerations and presents practical recommendations for evidence-based use. In addition to conventional formulations, attention is given to the emergence of nutritional gels and hydrogel-based delivery systems, which are increasingly investigated as strategies to improve portability, gastrointestinal tolerability, and bioavailability of bioactive compounds in high-demand civilian and occupational settings. These platforms illustrate a broader shift toward advanced supplement technologies and precision nutrition approaches.
