In brief: Overdose

Certain vitamins & minerals, including iron, can become toxic if you consistently take much more than your body needs.
One multivitamin is usually sufficient for most healthy people. Men & women who don't menstruate shouldn't take iron supplement unless specifically instructed under dr's care. Some supplements can interfere with absorption of others, so consult w/ practitioner if using several.
