Selenium

Selenium, an essential trace element found in soil and various foods, is vital for human health, acting as a cofactor for antioxidant enzymes, supporting immune function, and contributing to thyroid health and DNA synthesis. In medical contexts, selenium is actively employed in chelation therapy, particularly for heavy metal poisoning, such as mercury toxicity. Selenium's unique ability to form stable complexes with mercury is integral to reducing its harmful effects and facilitating elimination. However, it is crucial to exercise caution, as selenium toxicity can result from acute or chronic ingestion of excess selenium. Symptoms of selenium toxicity may include nausea, vomiting, nail discoloration, brittleness, and loss, hair loss, fatigue, irritability, and an unusual breath odor often described as "garlic breath." Individuals undergoing chelation therapy or considering selenium supplementation should be vigilant about proper dosages and seek the guidance of healthcare professionals to avoid potential adverse effects associated with selenium poisoning. Regular monitoring and adherence to recommended levels are essential for a safe and effective approach to selenium utilization.
