Iron deficiency aemnia really caught my attention too. In fact I investigated our vitamin supply at home and found that our gummy vitamins have NO iron in them at all. I looked it up and adult males requires from 0.5 to 1.0 mg iron daily. Females, menstrual age will require about double this amount. During pregnancy and lactation from 2 to 4 mg of iron per day. Prior to puberty and after menopause the female requires no more iron then the male.
