Selenium*
Selenium is a trace mineral that is important for thyroid function and immune health. Low levels of selenium can cause thyroid disorders and impaired immune function.
iollo markers that associate with Selenium*
Cysteine
Cysteine is an amino acid that contains a sulfur group. The selenium analog of cysteine, selenocysteine, is directly incorporated into selenoproteins. Cysteine and selenocysteine are structurally related.
