Vitamin Overdose and Pregnancy
During pregnancy, it is important to get the proper nutrients to foster healthy fetal development. You may be tempted to take a multivitamin in addition to other supplements. However, vitamin overdose can occur when an individual takes more than the recommended daily amount of a vitamin. This can result when taking more than one multivitamin, or when taking individual vitamins in addition to a multivitamin.
While any vitamin can be toxic if taken in large amounts, calcium and iron pose the greatest toxic risks when taken in excess. Taking a multivitamin during pregnancy is important, although it is best to talk with your doctor before taking any additional supplements to avoid overdosing.
