How many calcium and zinc bottles should pregnant women drink a day

Since there are two lives in the body of a pregnant woman, her body needs a lot of nutritional supplements at this time. Among them, trace elements are a nutrient that every pregnant woman must supplement, because if the body lacks trace elements, it will affect the healthy growth of the baby in the belly. Calcium and zinc are two trace elements that pregnant women need to supplement with specific health products. For a normal pregnant woman, how many calcium and zinc supplements should she drink in a day?

How much calcium should pregnant women supplement every day

The Chinese Nutrition Society recommends the following calcium intake: 800 mg per day in the first three months of pregnancy (the same as before pregnancy, the amount of calcium required has not increased); 1000 mg per day in the second trimester, i.e. the fourth, fifth and sixth months, because the fetus's teeth and bones begin to develop during this period, and the pregnant woman's calcium requirement increases by 200 mg; in the third trimester, i.e. the seventh, eighth and ninth months of pregnancy, the daily calcium requirement reaches 1200-1500 mg. This period is the last period of calcification of the fetus's teeth and bones, and the pregnant woman's calcium requirement increases by 400-700 mg, nearly doubling. The calcium intake in the diet is only about 400 mg, plus half a pound of milk contains 250 mg, so there is still a shortfall of at least 550 mg of calcium. Therefore, it is more necessary to take calcium tablets to reach the daily required amount, which is beneficial to the calcification of the fetus's teeth and bones. The calcium requirement during lactation is 1200-1500 mg, which also needs to be supplemented. Pregnancy and childbirth are special physiological periods for women, and the need for calcium is very high. It is generally recommended to take calcium supplements at least until the end of the breastfeeding period.

How much iron should pregnant women supplement daily?

Early pregnancy: From the sixth week of pregnancy, the amount of plasma in the body's blood increases more than red blood cells, causing the blood to be diluted and prone to "physiological anemia." The daily iron intake during this stage is 15 mg/day. You should eat more animal foods such as fish, lean meat, liver, eggs, dried shrimp and fresh vegetables. Pay attention to the combination of meat and vegetables, and eat more citrus fruits.

Second trimester: From the 13th to the 28th week, the daily iron intake for pregnant women is 25 mg. Since the main component of red blood cells is iron, in order to make up for the insufficient red blood cell content, additional iron is needed to produce more red blood cells. Expectant mothers should eat more meat, liver and other foods rich in hemoglobin and iron, and supplement with vitamin C to increase iron absorption.

Late pregnancy: From the 29th to the 40th week, it is more important for pregnant women to supplement iron, and the daily iron intake should reach 28 mg. During this stage, the fetus's liver stores iron at a rate of 5 mg per day until it reaches 300-400 mg of iron at birth. Pregnant women also need to prepare iron for blood loss during childbirth and breastfeeding. During this period, continue to eat more iron-rich foods and consume hemoglobin-type iron from animal foods. In addition, iron supplements can be taken under the guidance of a doctor.

How much zinc should pregnant women supplement daily?

Normal people need to supplement 12 mg to 16 mg of zinc from their diet every day, while pregnant women need 20 mg of zinc every day. The hazards of insufficient zinc intake: Failure to consume enough zinc can lead to abnormal differentiation of fetal brain cells and a decrease in the total number of brain cells; low birth weight of newborns and even developmental malformations. At the same time, blood zinc levels can also affect the contraction of the pregnant woman's uterus. When the blood zinc level is normal, the uterine contractions are strong; otherwise, the uterine contractions are weak. Therefore, attention should be paid to zinc supplementation to ensure the normal development of the fetus and smooth delivery of pregnant women.
