Dose and safetyThe dose that worked and the upper limit
The studies of selenium yeast taken by mouth that showed an improvement gave 200 mcg a day.
The upper limit for adults is 400 mcg of selenium a day, counted as the selenium itself, not the weight of the compound; above it, members see a note and are told they can take less.
