We do not recommend doubling up the daily value of prenatal vitamins as increased amounts of certain vitamins can be dangerous. In general, healthcare providers recommend increased folate intake with twins. Please talk to your healthcare provider about the recommended values. If you have a history of seizures and are on anticonvulsants, or if you have a history of a baby affected by a neural tube defect, talk to your healthcare provider about increased folate intake. Based on conversations with your healthcare provider, you can supplement with our MTHF Folate for reproductive health and fetal development.‡
