Take-away: Calcium and magnesium may best be taken in the evening with food or before nighttime sleep. Since zinc should not be taken with calcium and apart from iron, it is most useful if taken earlier in the day either slightly before/after food.

Zinc is an essential mineral that women require on a daily basis to stay healthy. Although zinc is needed in small amounts, a zinc deficiency can cause some serious and unpleasant side effects â like hair loss, problems with your sense of taste and smell or poor wound healing. Good sources of zinc include red meat, chicken, seafood, dairy products, legumes and nuts. According to the Office of Dietary Supplements, women need 8 milligrams of zinc each day; 11 milligrams if they are pregnant and 12 milligrams of zinc daily if they are breastfeeding.
