Effects of changes in iron (Fe) and zinc (Zn) status on cognition of premenopausal women were studied. Research in animals and humans shows that Fe and Zn influence brain function. Effects of mild Fe or Zn deficiencies on cognition of women have received limited attention. Therefore, using a double-blind randomized controlled treatment design the authors supplemented 34 sideropenic non-anemic women, ages 18-40 years, with micronutrients plus Fe, Zn, Fe+Zn, or micronutrients only. The micronutrient supplement was based on NRC guidelines. Eleven nonsideropenic women were also given the micronutrient supplement. Subjects were examined with the Weschler Memory Quotient (MQ) and Booklets Categories (BC) tests before and after treatment. After 8 weeks, significant improvement in MQ was displayed by the Fe, Zn and Fe+Zn groups, but no improvement occurred in the sideropenic subjects who were given only micronutrients. The nonsideropenic group displayed improved MQ when given only micronutrients. In contrast, all but the Fe group improved with the BC Test. The findings suggest that Fe and Zn repletion of sideropenic women improved certain cognitive functions of the women.
