Iron and Folic acid is staed during which period of pregnancy?
**Core Concept**
Iron and folic acid supplementation is a crucial aspect of prenatal care, particularly during the second and third trimesters of pregnancy. The primary goal is to prevent iron deficiency anemia and neural tube defects, respectively.
**Why the Correct Answer is Right**
The recommended start time for iron and folic acid supplementation is during the first trimester of pregnancy, usually around 4-6 weeks. This is because folic acid is essential for neural tube formation, and iron stores are often depleted by 12-16 weeks of gestation. The World Health Organization (WHO) and the American College of Obstetricians and Gynecologists (ACOG) recommend starting iron and folic acid supplementation as soon as pregnancy is confirmed.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it suggests starting supplementation too late, potentially leading to iron deficiency anemia and increased risk of preterm labor.
**Option B:** This option is incorrect because it implies that supplementation should only be started during the second trimester, which may not provide adequate time for folic acid to prevent neural tube defects.
**Option C:** This option is incorrect because it suggests that supplementation should only be started during the third trimester, which is too late to prevent iron deficiency anemia and neural tube defects.
**Clinical Pearl / High-Yield Fact**
It's essential to note that all pregnant women should receive a prenatal multivitamin containing folic acid (400-800 μg/day) starting from the first trimester, regardless of their dietary habits.
**Correct Answer:** C.
