Selenium – What is it?
Selenium is involved in selenoproteins, thyroid metabolism and antioxidant enzymes.
Where is it used?
It is found in multivitamins, immune and thyroid-support products.
Forms & Label
Selenomethionine, sodium selenite and other forms.
On the label, we examine the form, actual amount per serving and any standardization.
What do we know from the available evidence?
Only a small amount is needed, and a higher dose does not mean a better result.
The evidence varies by goal, and we should not equate marketing with clinical data.
Safety & Precautions
Chronically excessive intake may cause selenosis.
Pregnancy, breastfeeding, chronic conditions or medication use are reasons to seek individualized professional advice.
