A form of selenium
Selenium yeast supplements
351 selenium products in the NIH label database list selenium as selenium yeast (4% of the 7,934 selenium products); their median is 75 mcg of selenium per serving, against 55 mcg across all selenium products; the 49 whose only supplement ingredient is selenium list a median of 200 mcg (DSLD version 9.4.0, January 2026).
How does selenium yeast 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 selenium yeast?
A Supplement Facts row normally states the selenium itself (a row like "Selenium (as selenium yeast)"); a row named as the compound (a row like "Selenium yeast") 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 351 products here, 333 give the selenium in its own row (5 of them an amount far outside what other labels list, or one their own %DV disagrees with); 18 give no amount of their own or one in another unit.
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, 6 of the 328 selenium yeast products with a plausible amount (1.8%) give more than that.
