Advances in selenium supplementation: From selenium-enriched yeast to potential selenium-enriched insects, and selenium nanoparticles

ABSTRACT (as in your article/report/etc.): Selenium (Se) is an essential micronutrient that plays an important role in animal and human development and physiological homeostasis. Mulberry Heart Disease (MHD) in pigs and Keshan Disease (KD) in humans are few examples of important manifestations of Se deficiency. Selenium is deficient in soil in many places all around the world and Se biofortification is a popular approach to improve Se uptake and maintain human health. The use of Se fertilizers is already widely used in countries such as Finland or Russia where the problem of Se deficiency in soil is widespread, but this technique depends on the ability of plants to uptake Se from soil. This review focuses on innovative products like Se-enriched insects and Se-nanoparticles. Black Soldier Fly prepupae show biofortification when sodium selenite was added to their diet. They represent a valuable alternative to selenized yeasts in the supply of selenomethionine (SeMet) to livestock. At the same time, a new source of Se supplementation is facing on the scene. Selenium nanoparticles represents a more biocompatible and less toxic inorganic Se source, compared to selenite and selenate, to animal organisms.
