Pregnant women in Kacsir can eat calcium tablets for about 7-8 months, depending on their personal situation. You need to take 600mg of calcium every day in the first trimester, and gradually increase it to 1000mg and 1200mg in the second and third trimesters. If pregnant women are short of calcium, it is necessary to increase the intake of calcium tablets appropriately, but the dose and frequency should be controlled to avoid hypercalcemia. At the same time, pay attention to diet conditioning and eat more foods rich in calcium. It is best to supplement calcium under the guidance of a doctor.
