What is the recommended dose of folic acid for twins?

For women carrying twins, the recommended dose of folic acid is typically higher than for those with a singleton pregnancy to account for the increased risk of neural tube defects and other potential developmental issues. The dose of 1 mg (1000 micrograms) is considered sufficient for normal circumstances in multiple gestations. This amount is advised to ensure adequate folate levels in the mother, supporting proper fetal development and reducing the risk of congenital abnormalities associated with folate deficiency.

While lower doses may suffice for those without such risks, and higher doses can be warranted in case of previous neural tube defects or certain health conditions, 1 mg is the standard recommendation for twin pregnancies as it strikes a balance between providing adequate support without unnecessary excess. Higher doses such as 2 mg or 4 mg may be indicated for specific high-risk individuals but are not the routine recommendation for all women expecting twins.
