Pregnant women with a normal diet can start taking calcium tablets in mid-pregnancy, and the best time of day to take calcium tablets is after dinner or before bed.
The growth of the embryo in early pregnancy is slow, so the nutritional requirements are not very different from those before pregnancy, so just pay attention to a normal diet and supplement folic acid.
Fetal growth accelerated in mid-pregnancy needs to be supplemented with sufficient energy, iron, and to ensure the supply of fish, poultry, eggs, milk, lean meat, and appropriately increase the intake of milk, which is rich in protein and a good source of calcium, from the mid-pregnancy onwards, it is recommended that calcium supplements of 200 mg per day.
Since calcium synthesis can be promoted by light during the day, and blood calcium concentration will decrease at night, the best time to take calcium supplement during the day can be placed after dinner or before bedtime, which can increase the blood calcium concentration at night.
Nutritional balance is required during pregnancy, and nutritional clinics can be consulted if necessary.
