We did, however, carry out a
separate study in nonpregnant women in a similar slum
community in Mumbai, using the same supplements, specifically
to measure a range of micronutrients before and after 3 mo of
supplementation (vitamin C, b-carotene, retinol, ferritin, folate,
vitamin B-12, and homocysteine) and found that, of these,
only b-carotene concentrations increased (35).
