The Role of Selenium in Human Health: Biochemical Functions, Antioxidant Mechanisms, and Clinical Perspectives

Öz

Selenium (Se) is an essential trace element with a pivotal role in human health. Through its incorporation into selenoproteins, Se contributes to antioxidant defense, thyroid hormone metabolism, immune regulation, and maintenance of redox balance. Both deficiency and excess intake are linked to significant clinical outcomes. Deficiency has been associated with cardiovascular, endocrine, neurological, and immune dysfunctions, while excessive intake can lead to selenosis and toxicity. This review summarizes the digestion, absorption, and metabolism of Se; its biochemical significance through selenoproteins; its metabolic functions and associations with various diseases; analytical methods used for its measurement; and the emerging biomedical applications of selenium nanoparticles. Comparative insights with other trace elements are also provided. Evidence from epidemiological and clinical studies highlights the importance of maintaining Se levels within physiological ranges. Furthermore, national studies from Turkey indicate that the consequences of Se deficiency and excess on public health require further detailed investigation. Future research perspectives include randomized controlled trials, bioinformatics-based exploration of selenoprotein networks, and the clinical evaluation of Se nanoparticles as therapeutic agents. Public health approaches, including targeted supplementation and fortification programs, remain essential in Se-deficient regions.
