Pregnant women can take calcium tablets every day, but be careful not to overdo it. During pregnancy, under normal circumstances, usually after five months of pregnancy, after excluding the calcium absorbed by the diet, it is still necessary to supplement 1200 mg of calcium, so this time pregnant women take a calcium tablet containing about 1200 mg of calcium every day is OK. Pregnant women in early pregnancy, if there are symptoms of calcium deficiency, you need to go to the hospital to do calcium trace element examination, and then under the guidance of the doctor to take the appropriate dosage, not to take on their own. During pregnancy, pregnant women need to supplement any trace element tablets under the guidance of a gynecologist, who will formulate an individualized supplementation program according to the specific situation.
