Six randomized controlled studies show that providing daily selenium supplementation to HIV-infected adults increases CD4 cell counts, reduces the risk of diarrhea morbidity, and lowers hospital admission rates for HIV-related conditions and opportunistic infection in HIV-infected adults [Kayode 2020].
Alexander et al [2020] have recognized the importance of selenium to immune system function and have recommended the initiation of adequate selenium supplementation in high-risk Covid-19 areas and as soon as possible after a suspected Covid-19 infection.
Richie et al [2014] have shown that selenium supplementation in the form of selenium-enriched yeast provides significantly greater protection against oxidative stress than supplementation with exclusively selenomethionine does.
