Seems this should be filed in the "you should take enough of what you need enough of" section. But unless someone actually either tries to see of there is any change from supplementing, or tests and determines need from the results, it does seem ever so easy to walk on past this sort of issue.
Yet again, please can we have a "measure everything" technology that costs peanuts and works on our mobile phones?

Abstract
CONTEXT:
Selenium is an essential micronutrient for human beings. Selenoproteins play a role in anti-oxidation and in maintaining immunity. Selenoproteins are distributed in all tissues, the most important of which are glutathione peroxidase, thioredoxin reductase and deiodinases. The deiodinases are selenium-dependent enzymes.
ISSUES:
An elderly man with lethargy and tiredness who had normal free thyroid hormone T4, thyroid-stimulating hormone and a low T3 with subnormal temperature and low selenium level. Selenium supplementation normalised thyroid function tests.
LESSONS LEARNED:
Physicians should have high level of suspicion to identify selenium deficiency as an effective replacement will cure the causative disorder.
