What Is Thrombotic Thrombocytopenic Purpura? Thrombotic thrombocytopenic purpura (TTP) is a rare blood disorder. In TTP, blood clots form in small blood vessels throughout the body. The clots can limit or block the flow of oxygen-rich blood to the body's organs, such as the brain, kidneys, and heart. As a result, serious health problems can develop.

Iron is best absorbed on an empty stomach, so take it before you eat in the morning or when you go to bed at night. Certain foods and vitamins inhibit the absorption of iron. One of these is calcium, so be careful not to take your calcium at the same time as your iron supplement.
