“Selenium appears to aid in upkeep with the immune system that can work to inhibit viruses but inhibit doesn’t stop them.”
Yes it helps the immune system in other ways also, but you have to read the research paper here:
Persons with above a certain level of selenium in the blood plasma are immune to Ebola… completely! That is what spurred the research. In the presence of enough selenium in the plasma, the virus is unable to bond to the receptors, and is unable to infect a cell. Complete inhibition! It is chemical immunity.
Granted this does not work for all viruses, but it is true for the coronavirus family and others with similar protein keys for attacking receptors on cells. Colds, Flu, COVID, Ebola, among others. The selenium presence stops the viral ability to infect a cell at all.
