When should a pregnant woman take iodine supplements?

Iodine is essential during pregnancy for proper fetal development, particularly for thyroid function and brain development. A pregnant woman should take iodine supplements consistently throughout her pregnancy because iodine needs increase significantly at this time due to the demands of both the mother and the developing fetus.

Taking one tablet per day throughout pregnancy ensures that the woman's iodine levels are adequate, helping to prevent deficiencies that could lead to complications such as intellectual disabilities or impaired physical development in the baby. Consistent intake is vital, as the body cannot store iodine for prolonged periods, and fluctuations in dietary intake could lead to periods of deficiency.

This approach aligns with health guidelines that recommend daily supplementation of iodine for pregnant women, highlighting the importance of maintaining adequate levels throughout the entire pregnancy rather than limiting it to specific trimesters or stages of labor.
