A form of selenium

Sodium selenate supplements

709 selenium products in the NIH label database list selenium as sodium selenate (9% of the 7,934 selenium products); their median is 55 mcg of selenium per serving, against 55 mcg across all selenium products (DSLD version 9.4.0, January 2026).

How does sodium selenate compare with the other forms?

The median amount of selenium per serving in products naming each form; the count in brackets. The amount is the selenium the label gives, as printed (the Supplement Facts row normally states the element; a row named as the compound usually gives the compound's weight and is left out of these figures).

Is the amount the selenium or the whole sodium selenate?

A Supplement Facts row normally states the selenium itself (a row like "Selenium (as sodium selenate)"); a row named as the compound (a row like "Sodium selenate") usually states the compound's weight, which includes what the selenium is bound to and is larger than the selenium it supplies. The front of a bottle may print either. Of the 709 products here, 709 give the selenium in its own row (3 of them an amount far outside what other labels list, or one their own %DV disagrees with).

The adult Tolerable Upper Intake Level for selenium is 400 mcg a day; it covers total intake from food, water and supplements. At the most servings their labels direct, 1 of the 706 sodium selenate products with a plausible amount (0.1%) give more than that.
