Iodine and iodized salt in pregnancy

Role of iodine

Needed for maternal thyroid hormones and fetal neurodevelopment. Deficiency still occurs in some regions.

Sources

• Iodized table salt (muối i-ốt) in cooking — moderate use.
• Fish, dairy, eggs.
• Prenatal vitamins may include iodine — check labels.

Notes

• Do not exceed recommended intake; excess iodine also harms.
• Sea salt without iodine may not provide iodine unless labeled.
