Do you still need calcium supplementation during the second trimester of pregnancy if you're not deficient in calcium?
Generally, calcium supplements are not necessary during the second trimester of pregnancy if there is no calcium deficiency. It is recommended to consume more calcium-rich foods instead. The details are as follows:
The middle stage of pregnancy is a period of rapid fetal development. As the fetal skeleton begins to form, the demand for calcium increases significantly to meet the needs of both maternal health and fetal growth. If tests show that the pregnant woman is not deficient in calcium, additional calcium supplementation is not required, as excessive calcium intake may lead to an overly large fetal head circumference or placental aging, which could negatively affect both maternal health and fetal development.
To meet the calcium requirements of both mother and fetus, it is advisable to maintain a balanced diet and increase intake of calcium-rich foods such as tofu, dried shrimp, yam, dairy products, oysters, small shrimp, laver (seaweed), and similar items. Dietary sources can effectively support adequate calcium levels.
It is also recommended to get regular sun exposure to enhance calcium absorption. If symptoms of calcium deficiency occur—such as leg cramps or lower back pain—it is important to seek medical evaluation promptly and begin calcium supplementation under medical guidance.
