Selenium and Its Effects on Depression

Abstract

Daily intake of adequate doses is required to maintain health, prevent disease and slow down the aging process. Selenium; redox homeostasis, thyroid hormone metabolism, affecting the oxidative stress and inflammation protects the trace element with a wide area of pleiotropic effect. Selenium is vital for humans, but is a toxic element, depending on dose and specification.6 As with many other foods, the biological response to selenium depends on the sex, the nucleotide polymorphisms in the selenoprotein genes, the present state of the individual, the age of the individual and the presence of the disease. The active particle of selenium is selenocystein. Nutritional functions of selenium in humans are provided by selenoproteins, including selenocysteine. Knowing the role of selenoproteins in metabolism helps explain the consequences of selenium on human health. Glutathione peroxidase (Gpx) is the main selenoprotein found in most tissues in animals. Among the antioxidant defense theories, selenoproteins such as glutathione peroxidases (GPx) are thought to play an important role. The biosynthesis of selenoproteins depends on the presence of the essential trace element selenium. Thus, adequate intake of selenium is important for the preservation of brain function. Selenium deficiency may reveal many pathophysiological conditions including heart and neuromuscular disorders. While there is sufficient treatment for depression, a significant number of individuals still do not achieve improvement. Therefore, it is necessary to investigate modifiable risk factors and methods to prevent depression. Although the neuroprotective effect of selenium has not yet been clearly defined, the protective role of selenium in mood disorders may be related to the important effect of antioxidant defense. This review was conducted to investigate the effect of selenium on depression and other types of depression.
