                                According to the National Institutes of Health, women need between 1,000 and 1,200 milligrams of calcium daily depending on their age, but many women's multivitamins exclude this vital mineral. The primary reasons why don't women's multivitamins have calcium are complex interactions with other minerals, specifically iron, and the sheer physical size of the dosage required. This intentional omission is designed to maximize the effectiveness of the nutrients included in the supplement.
