INFLUENCE OF TRACE ELEMENTS ON THYROID FUNCTIONING: LITERATURE REVIEW

Abstract

Introduction: Trace elements, along with vitamins, constitute a heterogeneous group of micronutrients. Iodine, selenium and zinc are trace elements that interfere with the synthesis of thyroid hormones, but there are few studies that correlate clinical manifestations with a lack or excess of supplementation of these elements. This article searched for scientific evidence of the correlation of trace elements and the synthesis of thyroid hormones.Methodology: bibliographic search of documents from endocrinological scientific societies, systematic reviews and scientific studies.Objective: Explain the influence of trace elements on the proper functioning of the thyroid gland.Conclusion: Trace minerals such as iodine, selenium, and zinc are essential for normal thyroid metabolism. Its deficiency leads to clinical abnormalities, such as hypothyroidism, goiter, cretinism, among others. The deficiency of these trace elements remains a major public health problem facing many countries. The influence of micronutrients on thyroid function reveals the need for more research to expand scientific knowledge.
