Definition of Excess selenium
Excess selenium: Too much selenium (selenosis) which may cause reversible balding and brittle nails, give a garlic odor to the breath, and cause intestinal distress, weakness and slowed mental functioning. People who chronically consume more than the tolerable upper intake level (UL) of selenium -- in adults, the UL is 400 micrograms per day of selenium -- are at risk for developing selenosis.
