Should I double my prenatal diet if I’m expecting twins?

We do not recommend doubling your vitamin intake, as increasing the quantity of certain vitamins can be dangerous. In general, doctors recommend increasing folate intake in the case of twins. Please consult your doctor for the recommended values. If you have a history of epileptic seizures and are taking anticonvulsants, or if you have had a baby with a neural tube defect, talk to your doctor about increasing your folate intake.
