To obtain this information we will supplement 18 lactating women in Bangladesh who are likely to be depleted in MN. Mothers will spend 4 d in the family metabolic unit of International Center for Diarroheal Disease Research, Bangladesh (ICDDR,B). They will arrive fasted, and be given either 1X or 2X the RDA for lactation as a multiple MN supplement. At baseline and every time they breastfeed during 24h, they will be asked to feed the infant on one breast and collect the milk at intervals from the other breast. Meals fed will be low in MN. Samples will be analyzed separately and the 24 h secretion, intra-feed and diurnal variation of each MN determined in milk.
