Don't take your calcium and iron vitamins at the same time. Since they need the same absorption sites during digestion, they cancel each other out. I didn't know this (my nutritionist sucks) and always took them together. In any case, FYI. Calcium + multivitamin okay to take together. Iron with something citrucy is best (orange juice, etc, and not on an empty tummy), and calcium with food is best for digestion. Heard all this from a bariatric nutritionist at the OH Convention this past weekend

Another reason not to take them together.... it causes constipation! *~Amber~*
